## Background
This application is a continuation of U.S. patent application Ser. No. 13/193,744, filed Jul. 29, 2011, which claims priority to and the benefit of U.S. Provisional Patent Application No. 61/375,144, filed Aug. 19, 2010, the entire disclosure of which is incorporated herein by this specific reference.


Soft tissue replacement methods are commonly used for a wide variety of clinical and cosmetic purposes. One use involves reconstructive applications that rebuild and restore a body part or structure to correct deformities from congenital anomalies, trauma, cancer, infections, disease, or medication side effects. The replacement tissue serves to support surrounding tissue and to maintain the normal appearance of the body. The restoration of this normal appearance has an extremely beneficial psychological effect on post-operative patients, alleviating much of the shock and depression that often follows extensive surgical procedures. Another use involves augmentation applications that alter a body part or structure usually to improve its cosmetic or aesthetic appearance. Augmentation of the appearance also has beneficial psychological effects that improve self-esteem, well-being, and confidence of an individual. A third use involves structural applications that provides support to a body part or structure to improve its function, thereby alleviating a symptom associated with a disorder involving soft tissue loss. Examples of such disorders include, without limitation, stress urinary incontinence, fecal incontinence, vocal cord paralysis, vocal atrophy, vocal implantation, intubation trauma, post-hemilaryngectomy defects, irradiation damage, lumbar disc repair, and plantar footpad repair.
Soft tissue replacement methods currently rely on two general approaches: 1) implantation of artificial or alloplastic fillers like soft tissue implants, and injectable polymers and hydrogels; and 2) transplantation of tissue like tissue flaps and autologous tissue transfers. A drawback to the use of artificial or alloplastic fillers it that these inorganic materials lack any metabolic activity, do not become physiologically incorporated into the body, and as such, surrounding tissue and blood supply does not develop within the implanted material. In addition, artificial or alloplastic fillers risk migration and/or extrusion from the implant site. Furthermore, many of these fillers produce only temporary effects because the body rapidly reabsorbs them. Fillers providing long-term effects frequently induce a foreign body response resulting in formation of an avascular, fibrous capsule around the filler, which limits performance, distorts the aesthetic appearance of the surrounding area, and can cause pain to the individual. Furthermore, long-term fillers, like soft tissue implants, do not remodel with the aging tissue resulting in a material that may not be aesthetically acceptable as the patient's tissues undergo the normal physiologic changes associated with aging.
Although the use of transplanted tissue avoids the problems associated with artificial or alloplastic fillers, drawbacks are also associated with these procedures. In these procedures, loss of transplanted tissue volume over time as a result of its resorption by the body is a major problem. For example, transplantation of adipose tissue generally results in a loss of 20% to 90% of it volume one year after. This tissue loss is unpredictable and is a result of poor survival of the transplanted tissue due to necrosis and a lack of vascular formation. With respect to adipose tissue, tissue breakdown is associated with traumatic rupture of the cells, avascular necrosis, apoptosis of the adipocytes, inflammation secondary to apoptosis, fibrosis and contraction of the graft, and/or delipidation of the adipocytes with subsequent volume loss. Failed tissue grafts sometime produce stellate and irregular nodules with calcifications. As such, transplanted tissue methods are usually performed two or three times to obtain the desired effect, resulting in massive time and cost.
One of the major underlying causes for tissue breakdown seen in transplanted tissue methods is the lack of a blood supply sufficient to support the transplanted tissue. For example, alleviation of tissue ischemia is critically dependent upon formation of new blood vessels. The growth of new blood vessels and associated vasculature or repair or remodeling of existing blood vessels and associated vasculature provides collateral circulation in and around an ischemic area, improves blood flow, and alleviates the symptoms caused by the ischemia. Thus, compositions and methods that promote new blood vessel formation within a transplanted tissue are needed as this will improve the survival rate of such tissues, thereby achieving reliable long-term survival of grafted tissues.
The present specification provides novel compositions and soft tissue replacement methods using such compositions that reduce tissue volume loss by increasing the survival rate of the transplanted tissue. This improved survival rate is achieved by administering a compound that promotes new blood vessel formation, thereby ensuring that a blood supply adequate to support the transplanted tissue is established.
Thus, aspects of the present specification disclose a composition comprising adipose tissue and a compound having the structure of formula I,




wherein each dashed line represents the presence or absence of a bond; R1, R2 and R3 are each independently selected from H or C1-C6 alkyl; R6 is CO2H, CO2R7, CON(R7)2, CONHCH2CH2OH, CON(CH2CH2OH)2, CH2OR7, P(O)(OR7)2, or

BRIEF DESCRIPTION OF THE DRAWINGS
FIGS. 1-7 illustrate possible ways to prepare compounds disclosed herein.



DESCRIPTION
Insufficient blood vessel formation in a repairing or otherwise metabolically active tissue results in inadequate delivery of oxygen, nutrients, and other substances necessary to establish essential physiological functions to the area and promote wound healing. The formation of blood vessels within a tissue may occur by angiogenesis and/or vasculogenesis. As used herein, the term “angiogenesis” refers to a physiological process involving the growth of new blood vessels from pre-existing vessels and includes sprouting angiogenesis, the formation of new blood vessel by sprouting off existing ones, and splitting angiogenesis (intussusception), the formation of new blood vessel by splitting off existing ones. As used herein, the term “vasculogenesis” refers to a physiological process involving the de novo production of new blood-vessels by proliferating endothelial stem cells, and as such, the formation of new blood vessels when there were no pre-existing ones.
Blood vessel formation, whether angiogenesis or vasculogenesis, requires signals form growth factors and other proteins that direct and control the process, such as, e.g., fibroblast growth factors (like FGF-1 and FGF-2), vascular endothelial growth factors (like VEGF-A and VEGF-C), angiopoietins (like Ang-1 and Ang-2), platelet derived growth factor (PDGF), monocyte chemotactic protein-1 (MCP-1) (also known as chemokine (C—C motif) ligand 2 (CCL-2)), transformation growth factor betas (TGF-β1, TGF-β2, TGF-β3, and TGF-β4), vascular cell adhesion molecules (like VCAM-1), matrix metalloproteinases (like MMP-2 and MMP-9), integrins, cadherins, plasminogen activators, plasminogen activator inhibitors, and ephrin.
Of the factors listed above, two of the more critical factors essential to new blood vessel formation are FGF-2 and VEGF. One of the most important functions of fibroblast growth factor-2 (FGF-2 or bFGF) is the promotion of endothelial cell proliferation and the physical organization of endothelial cells into tube-like structures, thus promoting angiogenesis and vasculogenesis. FGF-2 is a more potent factor in new blood vessel formation than VEGF or PDGF. As well as stimulating blood vessel growth, FGF-2 is an important factor in wound healing. This factor stimulates proliferation of fibroblasts and endothelial cells that give rise to new vessel formation and developing granulation tissue; both increase blood supply and fill up a wound space/cavity early in the wound-healing process.
VEGF is another major contributor to new blood vessel formation. VEGF is a major contributor to new blood vessel formation. VEGF causes a massive signaling cascade in endothelial cells resulting in the release of many other factors known to be responsible in new blood vessel formation. For example, binding to VEGF receptor-2 (VEGFR-2) starts a tyrosine kinase signaling cascade that stimulates the production of factors that variously stimulate vessel permeability (eNOS, producing NO), proliferation/survival (FGF-2), migration (ICAMs/VCAMs/MMPs) and finally differentiation into mature blood vessels. In addition, in vitro studies demonstrated that upon stimulation by VEGF and FGF-2, endothelial cells would proliferate, migrate, and eventually form tube structures resembling capillaries.
The compounds disclosed herein, and compositions comprising such compounds, upregulate both FGF-2 and VEGF (see Example 2). In addition, both incisional and ulcer wound models demonstrate that the upregulation of FGF-2 and VEGF results in an improved wound healing response (see Example 2).
Without wishing to be bound by any particular theory, the compounds, compositions and methods disclosed herein increase the survival rate of transplanted tissue by promoting new blood vessel formation within the transplanted tissue. Administration of a compound, either as a composition with the transplanted tissue or as a prior or subsequent administration to the transplantation procedure, upregulate factors essential to new blood vessel formation, like FGF-2 and VEGF. This upregulation initiates the signaling cascade in endothelial cells responsible for the formation of new blood vessel. This initiation results in the formation of new blood vessels that, in turn, provide oxygen, nutrients, and other substances necessary to establish essential physiological functions to the transplanted tissue. This adequate blood supply supports the establishment, growth and survival of the transplanted tissue. Thus, the compounds, compositions and methods disclosed herein ameliorate or prevent one of the major underlying causes for the tissue breakdown of transplanted tissue, namely the lack of a blood supply sufficient to support the transplanted tissue. In addition, the compounds and compositions disclosed herein are superior to the mere addition of factors critical to new blood vessel formation, like FGF-2 and VEGF, because these small molecules are more stable and less costly then these protein-based therapies. Furthermore, formation of new blood vessels can soften scar tissue, capsular contracture by facilitating the remolding of fibrous tissue into normal soft tissue typical of the affected region.
Aspects of the present specification provide, in part, a composition comprising adipose tissue. As used herein, the term “adipose tissue” is synonymous with “fat” or “fatty tissue” and refers to a loose fibrous connective tissue comprising fat cells (adipocytes) and multiple types of regenerative cells. Adipose tissue may comprise brown and/or white adipose tissue taken from any body site, such as, e.g., subcutaneous, omental/visceral, interscapular, or mediastinal. It may be obtained from any organism having adipose tissue, or the adipose tissue used may be from a primary cell culture or an immortalized cell line.
Adipose tissue may be collected from the same individual who is undergoing the soft tissue replacement procedure (autograft), from a donor individual who is not the same individual as the one undergoing the soft tissue replacement procedure (allograft), or from an animal source (xenograft). As used herein, the term “autotransplantation” refers to the transplantation of organs, tissues, or cells from one part of the body to another part in the same individual, i.e., the donor and recipient are the same individual. Tissue transplanted by such “autologous” procedures is referred to as an autograft or autotransplant. As used herein, the term “allotransplantation” refers to the transplantation of organs, tissues, or cells from a donor to a recipient, where the donor and recipient are different individuals, but of the same species. Tissue transplanted by such “allologous” procedures is referred to as an allograft or allotransplant. As used herein, the term “xenotransplantation” refers to the transplantation of organs, tissues, or cells from a donor to a recipient, where the donor is of a different species as the recipient. Tissue transplanted by such “xenologous” procedures is referred to as a xenoqraft or xenotransplant.
Adipose tissue can be collected by any procedure that can harvest adipose tissue useful for the compositions and methods disclosed herein, including, without limitation a liposuction (lipoplasty) procedure or a lipectomy procedure. Procedures useful for collecting adipose tissue should minimize the trauma and manipulation associated with adipose tissue removed. Adipose tissue may be harvested from any suitable region, including, without limitation, a mammary region, an abdominal region, a thigh region, a flank region, a gluteal region, a trochanter region, or a gonadal region. Procedures useful for collecting adipose tissue are well known to a person of ordinary skill in the art. The selected procedures may be performed concomitantly with liposculpture.
A liposuction procedure harvests adipose tissue by aspirating the tissue using a cannula. The cannula may be connected to a syringe for manual aspiration or to a power assisted suction device, like an aspirator, adapted to collect the adipose tissue into a vacuum bottle. A liposuction procedure does not maintain an intact blood supply of the harvested tissue. The syringe may be a 10, 20 or 60 mL syringe fitted with a 12 or 14 gauge cannula. Non-limiting examples of liposuction procedures include suction-assisted liposuction (SAL), ultrasound-assisted liposuction (UAL), power-assisted liposuction (PAL), twin-cannula (assisted) liposuction (TCAL or TCL), or external ultrasound-assisted liposuction (XUAL or EUAL), or water-assisted liposuction (WAL). In addition, the liposuction procedures listed above can be used with any of the following procedures that vary the amount of fluid injected during the procedure, such as, e.g., dry liposuction, wet liposuction, super-wet liposuction, tumescent liposuction, or laser-assisted liposuction. An autologous soft tissue transfer procedure typically uses adipose tissue collected from a liposuction procedure.
Although the harvested tissue may be used directly to make the disclosed compositions, it is more typically processed to purify and/or enrich for healthy adipocytes and regenerative cells. For example, the harvested adipose tissue may be separated from any debris and/or contaminants such as, e.g., blood, serum, proteases, lipases, lipids and other oils, and/or other bodily fluids; tumescent fluid and/or other materials used in the liposuction procedure; and/or other impurities suctioned during the procedure. Methods useful in separating debris and/or contaminants from adipose tissue useful to make the disclosed compositions, including, without limitation, centrifugation, sedimentation, filtration, and/or absorption. In addition, or alternatively, the harvested adipose tissue may be processed by washing is a physiological buffer like saline to remove any debris and/or contaminants.
A lipectomy procedure harvests adipose tissue by surgical excision from a donor site in a manner that minimizes damage to the blood supply of the tissue using standard surgical operative procedures. This harvested tissue is then implanted into the region needing the soft tissue replacement. A tissue flap or tissue graft procedure typically uses adipose tissue collected from a lipectomy procedure. A tissue flap is a section of living tissue that maintained its blood supply as the tissue is moved from one area of the body to another.
A local flap uses a piece of skin and underlying tissue that lie adjacent to the wound, including adipose tissue. The flap remains attached at one end so that it continues to be nourished by its original blood supply, and is repositioned over the wounded area. A regional flap uses a section of tissue that is attached by a specific blood vessel. When the flap is lifted, it needs only a very narrow attachment to the original site to receive its nourishing blood supply from the tethered artery and vein. A musculocutaneous flap, also called a muscle and skin flap, is used when the area to be covered needs more bulk and a more robust blood supply. Musculocutaneous flaps are often used in breast reconstruction to rebuild a breast after mastectomy. As an example, the transverse rectus abdominus myocutaneous) flap (TRAM flap) is a tissue flap procedure that uses muscle, fat and skin from an abdomen to create a new breast mound after a mastectomy. This type of flap remains “tethered” to its original blood supply. In a bone/soft tissue flap, bone, along with the overlying skin, is transferred to the wounded area, carrying its own blood supply.
Typically, a wound that is wide and difficult or impossible to close directly may be treated with a skin graft. A skin graft is a patch of healthy skin that is taken from one area of the body, called the “donor site,” and used to cover another area where skin is missing or damaged. There are three basic types of skin grafts. A split-thickness skin graft, commonly used to treat burn wounds, uses only the layers of skin closest to the surface. A full-thickness skin graft might be used to treat a burn wound that is deep and large, or to cover jointed areas where maximum skin elasticity and movement are needed. As its name implies, a full-thickness (all layers) section of skin from the donor site are lifted. A composite graft is used when the wound to be covered needs more underlying support, as with skin cancer on the nose. A composite graft requires lifting all the layers of skin, adipose tissue, and sometimes the underlying cartilage from the donor site.
The amount of adipose tissue collected will typically vary from individual to individual and can depend on a number of factors including, but not limited to, amount of adipose tissue required for the soft tissue replacement method, aesthetic expectations, age, body habitus, coagulation profile, hemodynamic stability, co-morbidities, and physician preference. A liposuction procedure may harvests form about 1 mL to about 1500 mL of adipose tissue. A lipectomy procedure typically harvests about 1 g to about 5,000 g.
Adipose tissue comprises multiple regenerative cells. As used herein, the term “regenerative cell” refers to any cells that cause or contribute to complete or partial regeneration, restoration, or substitution of structure or function of an organ, tissue, or physiologic unit or system to thereby provide a therapeutic, structural or cosmetic benefit. Examples of regenerative cells include stem cells, progenitor cells, and precursor cells. As used herein, the term “stem cell” refers to a multipotent regenerative cell with the potential to differentiate into a variety of other cell types that perform one or more specific functions and has the ability to self-renew. Some of the stem cells disclosed herein may be pluripotent. Exemplary examples of stem cells include, without limitation, adipose-derived stem cells (ASCs; adipose-derived stromal cells), endothelial-derived stem cells (ESCs), hematopoietic stem cells (HSGs), and mesenchyma stem cells (MSCs). As used herein, the term “progenitor cell” refers to an oligopotent regenerative cell with the potential to differentiate into more than one cell type, or an unipotent regenerative cell with the potential to differentiate into only a single cell type, that perform(s) one or more specific functions and has limited or no ability to self-renew. Exemplary examples of progenitor cells include, without limitation, endothelial progenitor cells, keratinocytes, monoblasts, myoblasts, and pericytes. As used herein, the term “precursor cell” refers to a unipotent regenerative cell with the potential to differentiate into one cell type that performs one or more specific functions and may retain extensive proliferative capacity that enables the cells to proliferate under appropriate conditions. Exemplary examples of precursor cells include, without limitation, adipoblast (lipoblast or preadipocytes), de-differentiated adipocytes, angioblasts, endothelial precursor cells, fibroblasts, lymphoblasts, and macrophages.
Harvested adipose tissue can be supplemented with regenerative cells such as, e.g., stem cells, progenitor cells, and precursor cells. Regenerative cells may promote new blood vessel formation, diminish necrosis, and/or promote a supportive microenvironment in the transplanted tissue, thereby improving survivability of the transplanted tissue. Regenerative cells can be obtained from a variety of sources. For example, adipose tissue is rich in regenerative cells that have the ability to restore and reconstruct various soft tissue defects in response to local differentiation clues from the recipient site. As such, a portion of the collected adipose tissue may be further processed in order to purify regenerative cells that can then be added back to the remainder of the harvested adipose tissue in order to enrich this material for these cells. Exemplary methods describing such cell enrichment procedures can be found in, e.g., Hedrick and Fraser, Methods of Using Adipose Tissue-Derived Cells in Augmenting Autologous Fat Transfer, U.S. Patent Publication 2005/0025755, Yoshimura, et al., Characterization of Freshly Isolated and Cultured Cells Derived from the Fatty and Fluid Portions of liposuction Aspirates, J.

Surg. 32: 48-55 (2008); each of which is hereby incorporated by reference in its entirety.
In addition, harvested adipose tissue can be supplemented with regenerative cells obtained from cell cultures, such as, e.g., primary cell cultures and established cell cultures. For example, a portion of harvested adipose tissue from an individual can be cultured in a manner to produce primary cell cultures enriched for regenerative cells. Alternatively, established cell lines derived from regenerative cells from adipose tissue, or another tissue source, can be cultured, harvested, and added to adipose tissue collected form an individual. Exemplary methods describing such cell culture compositions and procedures can be found in, e.g., Casteilla, et al., Method for Culturing Cells Derived from the Adipose Tissue and Uses Thereof, U.S. Patent Publication 2009/0246182; Chazenbalk, et al, Methods of Producing Preadipocytes and Increasing the Proliferation of Adult Adipose Stem/Progenitor Cells, U.S. Patent Publication 2009/0317367; Kleinsek and Soto, Augmentation and Repair of Sphincter Defects with Cells Including Adipocytic Cells, U.S. Patent Publication 2008/0299213; Rehman, et al., Secretion of Angiogenic and Antiapoptotic Factors by Human Adipose Stromal Cells, Circulation 109: r52-r58 (2004); Kilroy, et al., Cytokine Profile of Human Adipose-Derived Stem Cells: Expression of Angiogenic, Hematopoietic, and Pro-Inflammatory Factors, J. Cell. Physiol. 212: 702-709 (2007); each of which is hereby incorporated by reference in its entirety.
Harvested adipose tissue may be immediately used to make the compositions disclosed herein. Alternatively, harvested adipose tissue, whether unprocessed or processed, may be stored for used at some future date. Harvested tissue is typically stored using a slow freezing method of the tissue to −20° C., with or without cryopreservatives. Stored adipose tissue can typically be stored for at least 6 months.

Compounds of Formula I Promote Synthesis of TGF-β and VEGF
This example illustrates that compounds of formula I promote formation of blood vessels.
To test whether the compounds of Formula I promote the formation of blood vessels, and incisional wound model was employed over a 14-day period. Sprague-Dawley rats (180-200 g) were anesthetized, the backs shaved, and a 2-cm long incision was made on the back skin of rats under sterile conditions, reaching the deep fascia. The wound was immediately closed with 4-0 sutures. The animals were topically treated with vehicle or Compound 1 at 0.004% twice daily. The vehicle contains ethanol 30%, propylene glycol 12%, dipropylene glycol 5%, benzyl alcohol 5%, glycerol 3% and normal saline 45%. Biopsy samples of skin wound tissues were analyzed with Western blots day-7 and day-14 post-surgery. Tissue samples about 1 mm thick were taken from both sides of the wound. Protein was extracted, and FGF-2/VEGF expression was monitored, with Western blot analysis.
Compound 1 treatment significantly enhanced the expression of FGF-2 by 60%, as normalized with 6-actin (a house-keeping gene) by day-7 of the experiment (P=0.004). This significantly different increase in FGF-2 synthesis persisted for the whole study period (P=0.04). VEGF expression increased 25% as normalized with β-actin, by Compound 1 treatment on day-7 (P=0.039). This significantly different increase is synthesis returned to the baseline by day-14. Such an increase in FGF-2 and VEGF is consistent with their role in new blood vessel formation. The up-regulation of FGF-2 and VEGF by Compound 1 treatment was also observed in studies using an oral ulcer wound model.
Example 3
Adipose Tissue Transplant for Breast Defect Correction
This example illustrates the use of compositions and methods disclosed herein for a breast defect correction.
A 32-year-old woman presented with complaints that the medial portions of her breast implants were visible, which accentuated the “bony” appearance of her sternum. In addition she felt her breast were too far apart. Pre-operative evaluation of the person includes routine history and physical examination in addition to thorough informed consent disclosing all relevant risks and benefits of the procedure. The physician evaluating the individual determines that she is a candidate for a soft tissue replacement method using the compositions and methods disclosed herein.
To begin the procedure, adipose tissue is harvested from the woman. The procedure is performed at the individual's bedside. The physician examines the individual's habitus for a suitable site or sites to harvest adipose tissue and selects the lateral and medial thigh regions. The harvested area is injected subcutaneously with a standard tumescent fluid solution containing a saline solution, 0.5% lidocaine, and about 0.001% epinephrine. Using an 11-blade scalpel, a small puncture wound is made in order to transverse the dermis. The blade is turned 360 degrees to complete the wound. A two-holed blunt harvesting cannula (3 mm inner diameter) connected to a vacuum pump at low negative pressure (0.5 atm) is then inserted into the subcutaneous adipose tissue plane. The cannula is then moved throughout the plane to disrupt the connective tissue architecture. The volume of aspirate obtained is about 300 mL. The harvest adipose tissue is processed by centrifugation at 3,000 g for 3 minutes to separate health adipocytes and regenerative cells from blood, infiltration fluid and cell debris.
A compound of formula I, such as, e.g., Compound 1, Compound 2, Compound 3, Compound 4, and/or Compound 5, is mixed with the processed adipose tissue. The amount of compound added is an amount sufficient to promote formation of a blood supply sufficient to support the transplanted tissue. This composition is then transferred to 3 mL syringes. One-holed blunt infiltration cannulas (3 mm inner diameter) are used to place the adipose tissue subcutaneously over the lateral sternum and medial breast bilaterally, 70 mL on the right and 50 mL on the left. The adipose tissue is administered in a tear like fashion to increase the surface area to volume ratio.
Alternatively, the adipose tissue is first administered into the individual, and a compound of formula I, such as, e.g., Compound 1, Compound 2, Compound 3, Compound 4, and/or Compound 5, is subsequently administered into the same, or in the vicinity of, the region where the adipose tissue was implanted.
The individual is monitored for approximately 7 days. The physician evaluates the engrafted tissue and determines that the engraftment was successful. Both the woman and her physician are satisfied with the results of the procedure. Approximately one month after the procedure, the woman indicates that his quality of life has improved.

The cannula is then moved throughout the plane to disrupt the connective tissue architecture. The volume of aspirate obtained is about 600 mL. The harvest adipose tissue is processed by centrifugation at 2,700 g for 5 minutes to separate healthy adipocytes and regenerative cells from blood, infiltration fluid and cell debris. The centrifuged adipose tissue is then washed once is a Ringer's saline solution with lactone.
A compound of formula I, such as, e.g., Compound 1, Compound 2, Compound 3, Compound 4, and/or Compound 5, is mixed with the processed adipose tissue. The amount of compound added is an amount sufficient to promote formation of a blood supply sufficient to support the transplanted tissue. This composition is then transferred to 10 mL syringes. One-holed blunt infiltration cannulas (3 mm inner diameter) are used to place the adipose tissue subcutaneously using axillary, periareolar, and inframammary routes bilaterally, 190 mL on the right and 245 mL on the left. The adipose tissue is administered in a tear like fashion to increase the surface area to volume ratio.
Alternatively, the adipose tissue is first administered into the individual, and a compound of formula I, such as, e.g., Compound 1, Compound 2, Compound 3, Compound 4, and/or Compound 5, is subsequently administered into the same, or in the vicinity of, the region where the adipose tissue was implanted.
The individual is monitored for approximately 7 days. The physician evaluates the engrafted tissue and determines that the engraftment was successful. Both the woman and her physician are satisfied with the results of the procedure. Approximately one month after the procedure, the woman indicates that his quality of life has improved.

Adipose Tissue Transplant for Breast Disorder
This example illustrates the use of compositions and methods disclosed herein for a breast disorder.
A 29-year-old woman presented with bilateral tuberous breast deformity. Pre-operative evaluation of the person includes routine history and physical examination in addition to thorough informed consent disclosing all relevant risks and benefits of the procedure. The physician evaluating the individual determines that she is a candidate for a soft tissue replacement method using the compositions and methods disclosed herein.
To begin the procedure, adipose tissue is harvested from the woman. The procedure is performed at the individual's bedside. The physician examines the individual's habitus for a suitable site or sites to harvest adipose tissue and selects the abdomen, buttock, lateral and medial thigh, and trochanter regions. Using a 12-blade scalpel, a small puncture wound is made in order to transverse the dermis. The blade is turned 360 degrees to complete the wound. A two-holed blunt harvesting cannula (3 mm inner diameter) connected to a syringe is then inserted into the subcutaneous adipose tissue plane. The cannula is then moved throughout the plane to disrupt the connective tissue architecture. The volume of aspirate obtained is about 1,400 mL.
The harvested adipose tissue is divided into two, approximately equal portions. One portion is processed by gravity sedimentation to separate health adipocytes and regenerative cells from blood, infiltration fluid and cell debris. The other portion is used to isolate regenerative cells. This portion is digested with 0.075% collagenase in buffered saline for 30 minutes on a shaker at 37° C. Regenerative cells are then separated from mature adipocytes and connective tissue by centrifuging at 800 g for 10 minutes. The pellet containing the regenerative cells is then washed three times with buffered saline. The washed regenerative cells are then added back to the sediment purified adipose tissue.
A compound of formula I, such as, e.g., Compound 1, Compound 2, Compound 3, Compound 4, and/or Compound 5, is mixed with the processed adipose tissue. The amount of compound added is an amount sufficient to promote formation of a blood supply sufficient to support the transplanted tissue. This composition is then transferred to 10 mL syringes. One-holed blunt infiltration cannulas (3 mm inner diameter) are used to place the adipose tissue subcutaneously in multiple planes axillary, periareolar, and inframammary routes bilaterally, 380 mL on the right and 370 mL on the left. The adipose tissue is administered in a tear like fashion to increase the surface area to volume ratio.
Alternatively, the adipose tissue is first administered into the individual, and a compound of formula I, such as, e.g., Compound 1, Compound 2, Compound 3, Compound 4, and/or Compound 5, is subsequently administered into the same, or in the vicinity of, the region where the adipose tissue was implanted.
The individual is monitored for approximately 7 days. The physician evaluates the engrafted tissue and determines that the engraftment was successful. Both the woman and her physician are satisfied with the results of the procedure. Approximately one month after the procedure, the woman indicates that his quality of life has improved.
