BACKGROUND OF THE INVENTION
The placenta is a temporary organ that surrounds the fetus during gestation. The placenta allows for transport of gases and nutrients, and also provides other metabolic and endocrine functions. The amniotic membrane (AM) is an avascular membranous sac that is filled with amniotic fluid. This membrane is the innermost membrane surrounding a fetus in the amniotic cavity. This tissue consists of an epithelial layer and a subadjacent avascular stromal layer. The chorion surrounds the amniotic membrane. The chorion consists of two layers: an outer layer formed by the trophoblast, and an inner layer formed by the somatic mesoderm; the amnion is in contact with the latter. The trophoblast is made up of an internal layer of cubical or prismatic cells, the cytotrophoblast or layer of Langhans, and an external layer of richly nucleated protoplasm devoid of cell boundaries, the syncytiotrophoblast. The umbilical cord connects the placenta to the fetus and transports oxygen to the fetus.

BRIEF DESCRIPTION OF THE DRAWINGS
The novel features of the invention are set forth with particularity in the appended claims. A better understanding of the features and advantages of the present invention will be obtained by reference to the following detailed description that sets forth illustrative embodiments, in which the principles of the invention are utilized, and the accompanying drawings of which:
FIG. 1 exemplifies the effects of treating macrophages with AMP. Tartrate Resistant Acid Phosphatase (TRAP) staining of macrophage cells, treated with amniotic membrane extract (AME), Hyaluronan and the Heavy Chains of Inter-α-inhibitor (HC-HA) complex, amniotic membrane lysate (AML), or amniotic membrane powder (AMP). TRAP is highly expressed in osteoclasts, which are bone-absorbing cells.
FIG. 2 exemplifies the performance of several tissue products (AME, HC-HA, AML, AMP) in inhibiting osteoclast formation. All AM derivates significantly inhibit osteoclast formation, and AMP prepared from different donors (AMP 1-5) consistently showed inhibitory activity that was more potent than AML.
FIG. 3 exemplifies the effects of AMP (amniotic membrane powder) on osteoclastogenesis. AMP dose (0-500 μg/ml protein) dependently inhibits the osteoclast formation.
FIG. 4 exemplifies the effects of AMP (amniotic membrane powder) on osteoclastogenesis. The color picture of TRAP colorimetric assay is provided.
FIG. 5 exemplifies the effects of AMP (amniotic membrane powder) on osteoclastogenesis. Osteoclast inhibition by AMP is measured by TRAP Colorimetric assay.
FIG. 6 exemplifies the effects of AMP (amniotic membrane powder) on osteoclastogenesis. IC50 of AMP on the osteoclast formation is calculated to be about 20.1 μg/ml.
FIG. 7 exemplifies the effects of γ-irradiation on AMP. No significant difference in inhibition of TRAP activity was seen in gamma-irradiated AMP versus non gamma-irradiated AMP.
FIG. 8 exemplifies the performance of AMP in inhibiting osteoclast formation. Powders were made from amniotic membrane (AMP), chorion (CHP), amnio-chorion (ACP), whole placenta (PLP), whole umbilical cord (UCP), and umbilical cord amniotic membrane (UAMP). Like HC-HA (5 μg/ml), AMP (200 μg/ml), ACP (100 μg/ml), PLP (100 μg/ml), and WUC (100 μg/ml) significantly inhibit osteoclast formation.
FIG. 9 exemplifies the effects of AMP on bone matrix mineralization. When ARS is measured quantitatively, cell treated with AMP (125 μg/ml) significantly promotes mineralization (p=0.0001).
FIG. 10 exemplifies the effects of AMP on macrophages. Macrophages were treated with AMP-1 to AMP-3 after one and two years in storage, no significant change was observed in inhibition of TRAP activity with increased storage time. TRAP activity was measured in macrophages by ELISA staining.
FIG. 11 exemplifies the effects of lyophilization on AMP. AM potency is not affected by placing AM at different locations in a lyophilizer. A total of 12 plates (each plate containing AM tissue from 1 donor) were lyophilized. Six samples were selected (1 inner plate and 1 outer plate for each of the 3 shelves: S1P1, S1P4, S2P1, S2P4, S3P1, S3P4) and were assayed for osteoclast potency.
FIG. 12 exemplifies a method of producing AMP. Wet AM is placed into a tube with a porous cap and is frozen. The tube containing the frozen AM is then placed into a flask and lyophilized overnight using a benchtop lyophilizer. The lyophilized AM tissue is then transferred into the jar. A grinding ball is dropped into the jar and the jar is sealed with a screw fit lid. The entire jar is immersed into liquid nitrogen and placed in the grinding mill. The grinded powder is transferred from the jar. Using a spatula, the powder is then transferred from the jar and surface of the grinding ball to be stored.
FIG. 13 exemplifies the effect of AMP on phagocytosis of apoptotic neutrophils by resting or LPS-stimulated macrophages. RAW264.7 cells (1×105/ml) were cultivated on the immobilized PBS control, HA (2 μg/well), AMP (10 μg protein/well), AME (2 μg HA/well), or HC-HA (2 μg HA/well) without or with LPS (1 μg/ml) stimulation for 6 days (n=3). The cell culture medium was then removed, and 100 μl of 2×106/ml of apoptotic neutrophils in IMDM (Iscove's Modified Dulbecco's Medium) [prepared by treatment of resting neutrophils isolated from the normal human peripheral blood with roscovitine (20 μM) for 8 h] were added to each well containing resting or LPS-stimulated macrophages. After incubation for 30 min at 37° C., each well was washed three times with the cold PBS, and cell lysates (including macrophages and phagocytosed neutrophils) were collected to determine human myeloperoxidase (MPO) by ELISA to measure phagocytosed neutrophils by macrophages. The relative phagocytosis index was derived from the amount of MPO in each cell lysate normalized with its total proteins. The phagocytosis index of the control without LPS (−LPS) is defined as 100%. An asterisk (*) indicates p value <0.05 when compared with PBS control in the same group (−LPS or +LPS).
FIG. 14 exemplifies the difference in potency of cryopreserved AMP (CryoTek Method) and dehydrated AMP (Purion® Process) at inhibiting giant cell (osteoclast) formation. RAW 264.7 cells were induced to form giant cells using RANKL and then treated with cryopreserved AM powder (AMP) and dehydrated AmnioFix Injectable (mAMP). Both powders demonstrated a dose-dependent inhibition of giant cell formation, however, the inhibition was significantly more potent with the cryopreserved AMP (p>0.05).
FIG. 15 exemplifies the dose-dependent effects of AMP on pre-osteoblastic MC3T3-E1 cells. FIG. 15A. The negative control, i.e., without induction, did not develop spindle-like shapes or spindle rings throughout the entire period of culturing. The monolayer center and periphery stained a beige color. The positive control, i.e., with induction, developed fusiform and spindle-like cells and appearance of spindle rings around D5 of culturing (D4 of induction). ARS staining showed a light maroon color in the center of the monolayer. In contrast, AMP treatment from concentration 62.5 μg/ml upwards left AMP particles that settled on top of the cell monolayer and obscured observation of the monolayer. MC3T3-E1 cells treated with only AMP but no induction showed no spindle ring along the edge and ARS staining showed a dark crimson with a light pink background. From 7.8 μg/ml to 31.25 μg/ml, the AMP particles did not completely cover the monolayer and cells showed fusiform and spindle shapes. Along the edge, spindle rings could be seen. ARS staining showed a light maroon staining in the center of the monolayer and a dark crimson color along the spindle ring similar to the positive control. FIG. 15B. ARS staining measured after 4M GnHCl extraction and measured at OD450 gave coefficient of variation ranging from 3% to 10%. The * symbol denotes statistical significance of p<0.05 when compared to the negative control without induction. The results showed that AMP dose-dependently promoted mineralization without inductive agents. As a matter of fact, addition of inductive agents with 250 μg/ml AMP as “the AMP negative control” was less than the same concentration with inductive agents, indicating that inductive agents dampened AMP's effect in promoting mineralization.
FIG. 16 exemplifies the effects of AMP on mineralization as compared to conventional agents. FIG. 16A. Phase contrast micrographs with or without ARS staining taken on Day 21 culturing (Day 20 of induction). Without induction medium, the negative control cells maintained a hexagonal shape with some fusiform shapes. Spindle-like shapes were not observed, and no spindle ring formed along the periphery. ARS stained the monolayer a light pink. With induction, the positive control cells attained spindle like shapes. Cell borders were more prominent and raised; a spindle ring formed along the periphery near the well edge. The monolayer center stained a maroon color, and the ARS stain concentrated in the spindle ring with an intense crimson red color. Treatment with AMP directly caused AMP particles to settle on the monolayer and obscured the morphology of the cells. However, near the culture well edge, gaps between the AMP particles showed lack of a prominent monolayer underneath in both groups. There was no difference in cell morphology between AMP treatment alone and AMP treatment with induction. The cells that were visible were spindle like in shape. No spindle ring like the positive control was observed. ARS staining showed a crimson red staining in the center with reddish-brown staining along the periphery. Staining color and patterns were indistinguishable between the induction and no-induction groups. FIG. 16B. ARS staining was quantified on Day 21 of culture (Day 20 of induction). GnHCl successfully extracted the ARS dye and the coefficient of variation in OD450 values ranged from 2% to 15%. The * symbol denotes statistical significance of p<0.05 from the positive control. This result indicated that AMP alone was more effective in promoting mineralization than the inductive agent.
FIG. 17 demonstrates that AMP enhances mineralization of MC3T3-E1 cells. FIG. 17A. Phase contrast micrographs with or without ARS staining taken on Day 21 of culturing (Day 20 of induction). Without the induction medium, the negative control cells maintained a hexagonal shape with some fusiform shapes. Spindle-like shapes were not observed, and no spindle ring formed along the periphery. ARS stained the monolayer a light pink. With induction, the positive control cells attained spindle like shapes. Cell borders were more prominent and raised; a spindle ring formed along the periphery near the well edge. The monolayer center stained a maroon color, and the ARS stain concentrated in the spindle ring with an intense crimson red color. Treatment with AMP through a transwell (without direct contact with cells) did not produce AMP particle settlement on the monolayer. Cells were elongated and spindle-like, with spindle ring formation along the well edge. Like the positive control, the monolayer center stained a maroon color, and ARS dye concentrated in the spindle ring with an intense crimson red color. FIG. 17B. ARS staining was quantified on Day 21 of culture (Day 20 of induction). GnHCl successfully extracted the ARS dye and the coefficient of variation in OD450 values ranged from 2% to 15%. The * symbol denotes statistical significance of p<0.05 when compared to the positive control. The results showed that AMP alone without induction caused a significant more mineralization than the positive control containing the inductive agent if AMP was in direct contact with cells, but not if AMP was not in direct contact with cells.
FIG. 18 demonstrates that AMP does not increase cell proliferation in MC3T3-E1 cells. FIG. 18A. MTT Assay of MC3T3-E1 cell viability and metabolic activity on Day 1, 2, and 4. In untreated MC3T3-E1 cells, cell viability increases from Day 1 to Day 4. In AMP-treated cells, cell viability decreased on Day 2 and then more than doubled on Day 4, following the trend of the cells only group. The * symbol denotes statistical significance of p<0.05 from Day 1. FIG. 18B. BrdU Assay of MC3T3-E1 cell proliferation on Day 1, 2, and 16. BrdU assay showed decrease in cell proliferation following Day 1 in both the cells only group and AMP-treated cell group. Cell proliferation in the cells only group decreased by more than half by Day 2 and continued to decrease on Day 16. In AMP-treated cells, cell proliferation showed a statistically significant decrease only by Day 16. The * symbol denotes statistical significance of p<0.05 from Day 1.
FIG. 19 demonstrates that AMP alone can induce human bone marrow mesenchymal stem cells (hBMMSCs) and human amniotic membrane stromal stem cells (hAM Stroma) to undergo osteogenesis and mineralization. FIG. 19A. Phase contrast micrographs with or without ARS staining of HUVEC, hBMMSCs, and hAM stromal stem cells from Day 4 to Day 21. HUVEC cells formed a net-like pattern of cell growth by Day 4. However, there was significant cell death with dead cells settled on top of the network of cells until Day 21. Most of the HUVEC cells could not be fixed with 10% paraformaldehyde and the few cells stained with ARS showed a dark brown color. Although AMP settled on top of the HUVEC cells and covered the network of cells, the AMP particles detached from the plastic well with the cells upon ARS staining; the few remaining AMP particles also stained a dark brown. hBMMSCs, without induction, maintained a long fibroblastic shape. With induction, MSCs became elongated with more raised cell edges by Day 4. By Day 10, induced MSCs developed spindle-like cells, and cells grew and overlapped each other on the monolayer. On Day 17, the overlapping spindle cells formed a dense ring about 5 mm from the center of well. ARS staining showed that the uninduced MSCs monolayer stained a cream color, and the spindle ring stained a reddish orange color. AMP-treated MSCs contained AMP particles that covered the monolayer. With time, the monolayer retracted around concentrated areas of AMP particles. ARS staining showed a deep red-brown color. hAM stromal stem cells, without induction, maintained a rectangular shape. By Day 4, with induction, cell morphology changed and cells elongated with some developing fusiform shapes. AMP particles settled and covered some of the monolayer by Day 4 in AMP-treated stroma cells. The cells not covered by AMP particles in Day 4 were rectangular in shape. By Day 17, cells not covered by AMP particles were elongated like induced stroma cells in the positive control. By Day 21, AMP particles covered the well and cells morphology could not be observed. ARS staining showed the uninduced cells staining a cream color, while the induced cells stained a light pink color. The AMP-treated cells stained a deep red-brown color similar to the AMP-treated hBMMSCs. FIG. 19B. Cells were stained with ARS on Day 21 (Day 20 of induction for the positive control) and the extract with 4M GnHCl yielded the coefficient of variation in OD450 values ranged from 2% to 15%. The * symbol denotes statistical significance of p<0.05 when compared to the negative control. No mineralization was noted in the negative control of HUVEC with either inductive agent or AMP. Nonetheless, for both hBMMSC and hAM stromal stem cells, mineralization was promoted by the inductive agent, which was less than that promoted by AMP.
FIG. 20 exemplifies the effects of grinding AM in the presence of liquid nitrogen. TRAP activity of osteoclasts was assayed after treatment with AMP samples prepared with or w/o liquid nitrogen. At 50 μg/ml protein, AMP prepared with or w/o liquid nitrogen significantly inhibited osteoclast formation. There was no significant difference in AMP prepared with or w/o liquid nitrogen (p=0.82).

Certain Terminology
As used herein, “fetal support tissue” means tissue used to support the development of a fetus. Examples of fetal support tissue include, but are not limited to, (i) placental amniotic membrane (PAM), or substantially isolated PAM, (ii) umbilical cord amniotic membrane (UCAM) or substantially isolated UCAM, (iii) chorion or substantially isolated chorion, (iv) amnion-chorion or substantially isolated amnion-chorion, (v) placenta or substantially isolated placenta, (vi) umbilical cord or substantially isolated umbilical cord, or (vii) any combinations thereof.
As used herein, “fetal support tissue powder product” means a powder or any other product resulting from grinding fetal support tissue. Examples of fetal support tissue include, but are not limited to, (i) placental amniotic membrane (PAM), or substantially isolated PAM, (ii) umbilical cord amniotic membrane (UCAM) or substantially isolated UCAM, (iii) chorion or substantially isolated chorion, (iv) amnion-chorion or substantially isolated amnion-chorion, (v) placenta or substantially isolated placenta, (vi) umbilical cord or substantially isolated umbilical cord, or (vii) any combinations thereof.
As used herein, “powder” means matter in the form of fine dry particles or matrix. In some embodiments, the particles are not uniform in size. In some embodiments, the particles are substantially uniform in size.
As used herein, “grinding” means any method of reducing fetal support tissue to small particles or a powder. The term grinding includes micronizing, pulverizing, homogenizing, filing, milling, grating, pounding, and crushing.
As used herein, “placenta” means the organ that connects a developing fetus to the maternal uterine wall to allow nutrient uptake, waste elimination, and gas exchange via the maternal blood supply. The placenta is composed of three layers. The innermost placental layer surrounding the fetus is called amnion. The allantois is the middle layer of the placenta (derived from the embryonic hindgut); blood vessels originating from the umbilicus traverse this membrane. The outermost layer of the placenta, the chorion, comes into contact with the endometrium. The chorion and allantois fuse to form the chorioallantoic membrane.
As used herein, “chorion” means the membrane formed by extraembryonic mesoderm and the two layers of trophoblast. The chorionic villi emerge from the chorion, invade the endometrium, and allow transfer of nutrients from maternal blood to fetal blood. The chorion consists of two layers: an outer layer formed by the trophoblast, and an inner layer formed by the somatic mesoderm; the amnion is in contact with the latter. The trophoblast is made up of an internal layer of cubical or prismatic cells, the cytotrophoblast or layer of Langhans, and an external layer of richly nucleated protoplasm devoid of cell boundaries, the syncytiotrophoblast. The avascular amnion is adherent to the inner layer of the chorion.
As used herein, “amnion-chorion” means a product comprising amnion and chorion. In some embodiments, the amnion and the chorion are not separated (i.e., the amnion is naturally adherent to the inner layer of the chorion). In some embodiments, the amnion is initially separated from the chorion and later combined with the chorion during processing.
As used herein, “umbilical cord” means the organ that connects a developing fetus to the placenta. The umbilical cord is composed of Wharton's jelly, a gelatinous substance made largely from mucopolysaccharides. It contains one vein, which carries oxygenated, nutrient-rich blood to the fetus, and two arteries that carry deoxygenated, nutrient-depleted blood away.
As used herein, “placental amniotic membrane” (PAM) means amniotic membrane derived from the placenta. In some embodiments, the PAM is substantially isolated.
As used herein, “umbilical cord amniotic membrane” (UCAM) means amniotic membrane derived from the umbilical cord. UCAM is a translucent membrane. The UCAM has multiple layers: an epithelial layer; a basement membrane; a compact layer; a fibroblast layer; and a spongy layer. It lacks blood vessels or a direct blood supply. In some embodiments, the UCAM is substantially isolated. In some embodiments, the UCAM comprises Wharton's Jelly. In some embodiments, the UCAM comprises blood vessels and/or arteries. In some embodiments, the UCAM comprises Wharton's Jelly and blood vessels and/or arteries.
“Substantially isolated” or “isolated” means that the fetal support tissue powder product has been separate from undesired materials (e.g., red blood cells, blood vessels, and arteries) derived from the original source organism. Purity, or “isolation” may be assayed by standard methods, and will ordinarily be at least about 10% pure, more ordinarily at least about 20% pure, generally at least about 30% pure, and more generally at least about 40% pure; in further embodiments at least about 50% pure, or more often at least about 60% pure; in still other embodiments, at least about 95% pure.
As used herein, “biological activity” means the activity of polypeptides and polysaccharides. In some embodiments, the activity of polypeptides and polysaccharides found in umbilical cord (and substantially isolated umbilical cord), UCAM (and substantially isolated UCAM), placenta (and substantially isolated placenta), PAM (and substantially isolated PAM), chorion (and substantially isolated chorion), or amnion-chorion (and substantially isolated amnion-chorion).
As used herein, the substantial preservation of biological activity or structural integrity means that when compared to the biological activity and structural integrity of non-processed tissue, the biological activity and structural integrity of the fetal support tissue powder product has only decreased by about 5%, about 10%, about 15%, about 20%, about 25%, about 30%, about 35%, about 40%, about 50%, or about 60%.
The term “fresh” refers to tissue that is less than 10 days old following birth, and which is in substantially the same form as it was following birth.
The terms “subject” and “individual” are used interchangeably. As used herein, both terms mean any animal, preferably a mammal, including a human or non-human. The terms patient, subject, and individual are used interchangeably. None of the terms are to be interpreted as requiring the supervision of a medical professional (e.g., a doctor, nurse, physician's assistant, orderly, hospice worker).
The terms “treat,” “treating” or “treatment,” as used herein, include alleviating, abating or ameliorating a disease or condition symptoms, preventing additional symptoms, ameliorating or preventing the underlying metabolic causes of symptoms, inhibiting the disease or condition, e.g., arresting the development of the disease or condition, relieving the disease or condition, causing regression of the disease or condition, relieving a condition caused by the disease or condition, or stopping the symptoms of the disease or condition either prophylactically and/or therapeutically.
As used herein, a “biologically compatible aqueous solution” refers to a solution having a pH and osmotic properties (e.g., tonicity, osmalality and/or oncotic pressure) suitable for maintaining the integrity of biological cells and/or tissues. Suitable biologically compatible aqueous solutions typically have a pH between 4 and 8.5 and are isotonic or only moderately hypotonic or hypertonic.
As used herein, “syringeable” refers to a composition being flowable through the tip of a hypodermic needle upon mild to moderate pressure.

Initial Processing
Fetal support tissue is obtained from any suitable source (e.g., a hospital or tissue bank). Fetal support tissue may be obtained from any mammal, such as a human, non-human primate, cow or pig.
In some embodiments, the fetal support tissue is frozen (e.g., at or below 0° C.) until donor and specimen eligibility has been determined. In some embodiments, freezing the fetal support tissue kills substantially all cells found in the fetal support tissue. In some embodiments, freezing the fetal support tissue kills substantially all cells found in fetal support tissue while maintaining or increasing the biological activity of the fetal support tissue relative to fresh (i.e., non-frozen) fetal support tissue. In some embodiments, freezing the fetal support tissue results in the loss of metabolic activity in substantially all cells found in the fetal support tissue. In some embodiments, freezing the fetal support tissue results in the loss of metabolic activity in substantially all cells found in the fetal support tissue while maintaining or increasing the biological activity of the fetal support tissue (e.g., its anti-inflammatory, anti-scarring, anti-antigenic, and anti-adhesion properties) relative to fresh (i.e., non-frozen) fetal support tissue.
In some embodiments, the fetal support tissue is not frozen. If the fetal support tissue is not frozen, it is processed as described immediately below.
All processing is done following Good Tissue Practices (GTP) to ensure that no contaminants are introduced into the fetal support tissue powder products.
The fetal support tissue is tested for HIV-1, HIV-2, HTLV-1, hepatitis B and C, West Nile virus, cytomegalovirus, human transmissible spongiform encephalopathy (e.g., Creutzfeldt-Jakob disease) and treponema pallidum using an FDA licensed screening test. Any indication that the tissue is contaminated with HIV-1, HIV-2, HTLV-1, hepatitis B and C, West Nile virus, or cytomegalovirus results in the immediate quarantine and subsequent destruction of the tissue specimen.
Further, the donor's medical records are examined for risk factors for and clinical evidence of hepatitis B, hepatitis C, or HIV infection. Any indication that the donor has risk factors for, and/or clinical evidence of, infection with HIV-1, HIV-2, HTLV-1, hepatitis B and C, West Nile virus, cytomegalovirus, human transmissible spongiform encephalopathy (e.g., Creutzfeldt-Jakob disease) and treponema pallidum results in the immediate quarantine and subsequent destruction of the tissue specimen.
In some embodiments, substantially all blood is removed from the fetal support tissue. In some embodiments, substantially all blood is removed from the fetal support tissue before the fetal support tissue is frozen.
In some embodiments, blood is not removed from the fetal support tissue. In some embodiments, blood is not removed from the fetal support tissue before the fetal support tissue is frozen.

Miscellaneous Formulations
In some embodiments, a fetal support tissue powder product disclosed herein is administered as a dermal paint. As used herein, paints (also known as film formers) are solutions comprised of a solvent, a monomer or polymer, an active agent, and optionally one or more pharmaceutically-acceptable excipients. After application to a tissue, the solvent evaporates leaving behind a thin coating comprised of the monomers or polymers, and the active agent. The coating protects active agents and maintains them in an immobilized state at the site of application. This decreases the amount of active agent which may be lost and correspondingly increases the amount delivered to the affected area of the skin of an individual. By way of non-limiting example, paints include collodions (e.g. Flexible Collodion, USP), and solutions comprising saccharide siloxane copolymers and a cross-linking agent. Collodions are ethyl ether/ethanol solutions containing pyroxylin (a nitrocellulose). After application, the ethyl ether/ethanol solution evaporates leaving behind a thin film of pyroxylin. In solutions comprising saccharide siloxane copolymers, the saccharide siloxane copolymers form the coating after evaporation of the solvent initiates the cross-linking of the saccharide siloxane copolymers.

Treatment of Glaucoma
As used herein, “Glaucoma” means a disorder characterized by the loss of retinal ganglion cells in the optic nerve. In certain instances, glaucoma partially or fully results from an increase in intraocular pressure in the anterior chamber (AC). Intraocular pressure varies depending on the production of liquid aqueous humor by the ciliary processes of the eye and the drainage of the aqueous humor through the trabecular meshwork.
Glaucoma Drainage Devices (GDD) are medical devices that are implanted into an eye to relieve intraocular pressure by providing an alternative pathway for the aqueous humor to drain. If left uncovered, a GDD tube will erode and leave the eye susceptible to intraocular infection. Thus, the GDD tube needs to be covered. Currently, patches used to cover GDD tubes are made from pericardium, sclera and cornea. These patches are about 400-550 microns thick. The thinness of these patches results in their melting by 25% in 2 years potentially leaving the shunt tube exposed again.
In some embodiments, a fetal support tissue powder product disclosed herein is applied to a substrate and the substrate/fetal support tissue powder product is used to cover GDD tubes.

Example 10
AMP Inhibits Osteoclast Formation from RANKL Stimulated RAW 264.7 Macrophage Cells
Murine RAW 264.7 macrophage cells were seeded at a density of 4.0×103 cells/96 well (30-40% confluent), cultured in a-MEM media without Phenol Red and supplemented with 10% FBS, 100 μg/ml penicillin & streptomycin. 24 hours after seeding, cells were treated with or without 50 ng/ml RANKL stimulation. Experimental groups were simultaneously treated with AMP, AML or AME with protein concentration of 200 ug/ml. On Day 5, the culture was terminated and analyzed by TRAP staining and TRAP ELISA. The result from TRAP staining shows that osteoclasts (multi-nucleated cells) were not found on the negative control while large multi-nucleated cells were found on the positive control. AME inhibited osteoclast formation but did not inhibit RAW macrophage cell proliferation. Osteoclast formation and RAW macrophage cell proliferation were also inhibited by AML-1 and AML-2 (2 different donors), but such inhibition was not complete because small multi-nucleated cells could be seen after TRAP staining Osteoclast formation and RAW macrophage cell proliferation were also inhibited by AMP from 5 different donors at the same protein concentration of 200 ug/ml as AML. The result from TRAP staining shows that inhibitory action for osteoclast formation was seen on all AM derivatives. There was no significant difference between the TRAP ELISA reading between AMP and AME. For two donors, the TRAP ELISA reading for AMP is significantly lower than AML from the same donor (p=004 and p=0.02) at the same protein concentration 200 ug protein/ml. These data suggest that AMP performs better at inhibiting osteoclast formation compared to AML at the same protein concentration of 200 ug/ml (FIGS. 1-2 and Tables 1-3).

TRAP Assay
Murine RAW 264.7 macrophage cells were seeded at a density of 4.0×103 cells/96 well (30-40% confluent), cultured in α-MEM media without Phenol Red and supplemented with 10% FBS, 100 μg/ml penicillin & streptomycin. 24 hours after seeding, cells were treated with or without 50 ng/ml RANKL stimulation. Experimental groups were simultaneously treated with AMP, AML or AME with protein concentration of 200 μg/ml. On Day 5, the culture was terminated and analyzed by TRAP staining and TRAP Colorimetric Assay.
Osteoclast formation and RAW macrophage cell proliferation were also inhibited by AMP from 5 different donors (FIG. 2) at the same protein concentration of 200 μg /ml as AML.
The result from TRAP staining shows that the inhibitory action for osteoclast formation was seen with all AM derivatives.

Murine RAW 264.7 macrophage cells were seeded at a density of 4.0×103 cells/96 well (30-40% confluent), cultured in α-MEM media without Phenol Red and supplemented with 10% FBS, 100 μg/ml penicillin & streptomycin. 24 hours after seeding, cells were treated with or without 50 ng/ml RANKL stimulation. Experimental groups were simultaneously treated with AMP, CHP, ACP, PLP, UCP, and UCAP with protein concentration of 100 μg/ml. On Day 5, the culture was terminated and analyzed by TRAP Colorimetric Assay.
Osteoclast formation was inhibited by all powder derived from amniotic membrane (AMP), chorion (CHP), amnio-chorion (ACP), placenta (PCP), whole umbilical cord (UCP), and umbilical cord AM (UCAP) (FIG. 8).
Example 34
AMP Promotes the Mineralization of Osteoblasts
Osteoblast precursor MC3T3-E1 cells were maintained in DMEM/10% FBS but were re-suspended into a-MEM/10% FBS and seeded at 1×105/ml on 24 well plastic (2 ml per well, and designated as Day 1 from here onwards) for 2 days.
The culture medium was replaced with either PBS (Neg. Ctrl), osteoblast-inducing reagents (0.2 mM ascorbic acid 2-phosphate and 10 mM glycerol 2-phosphate, Pos. Ctrl), or osteoblast-inducing reagents plus 0.1 μg/ml HC-HA or 125 μg/ml AMP. The cell culture medium was changed every 3 days until on Day 18. From Day 8 onwards, the osteoblast-inducing reagents was additionally supplemented with melatonin (50 ng/ml).
Treatment with AMP (125 μg/ml) yields dark staining (AMP), indicating that minerals are generated (FIG. 9).
After ARS stained cells were removed by 4 M GnCl, few cells were left in AMP treated wells (FIG. 9). Some cells migrate from the monolayer into the AMP particles and use it as a scaffold for differentiation and mineralization.
Quantitative measurement of ARS (FIG. 9) shows cells treated with AMP (125 μg/ml) significantly promote the mineralization compared to either the positive control or HC-HA (p=0.0001). The color changes related to the concentrations of alizarin red or in samples are shown in FIG. 9.
