Title: Topical Exosome Compositions and Associated Methods

Description:
CROSS REFERENCE TO RELATED APPLICATION 
     This application claims the benefit of, and priority to, U.S. Provisional Patent Application Ser. No. 62/877,155, filed Jul. 22, 2019, the entirety of which is incorporated by reference and commonly owned. 
    
    
     FIELD OF THE INVENTION 
     The present disclosure relates generally to topical exosome compositions for use in treating a variety of conditions in a subject, as well as methods of making and using the same. 
     BACKGROUND 
     Extracellular vesicles (EVs) including exosomes, microvesicles, and apoptotic bodies are nanoscale spherical vesicles that are released when the multivesicular bodies (MVBs) fuse with the cell plasma membrane. Consequently, they bud and are shed into the extracellular space and bodily fluids. Exosomes are increasingly important in cell biology because of their role in cell-to-cell communication and transfer of cellular materials, such as miRNA, lncRNA, mRNA, proteins, and DNA. This mechanism implies that exosomes underlie some illnesses such as cancer, neurological, cardiovascular, and rheumatologic diseases. Different cell types grown in vitro constantly and constitutively secrete exosomes into the culture media. Therefore, the conditioned culture medium of cells serves as the very food for exosome manufacturing. Notably, many biopharmaceutical companies are already producing the exosomes during the cell culture processes, but these exosomes are discarded as a waste by-product. Exosomes, however, can be applied in different translational paradigms comprising diagnostics, therapeutics, and research. The embodiments disclosed herein are aimed at fulfilling these and other needs in the art.

Other pharmaceutical dosage forms may also be used to deliver drugs including but not limited to injectables for dermal drug delivery. 
     Reference throughout this specification to “one embodiment”; “an embodiment”; “one or more embodiments”; or the like means that a particular feature, structure, step, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, appearances of the phrases “in one embodiment”; “in an embodiment”; “one or more embodiments”; or the like in various places throughout this specification are not necessarily all referring to the same embodiment. Moreover, the individual elements of a composition or steps in a method may be interchanged between the various exemplary embodiments without departing from the scope of the present disclosure. 
     In addition, for the purpose of promoting an understanding of the principles of the present disclosure, reference will now be made to the embodiments described herein, and specific language will be used to describe the same. It will, nevertheless, be understood that no limitation of the scope of the disclosure is thereby intended, and any alterations and further modifications of the described or illustrated embodiments and any further applications of the principles of the disclosure as illustrated herein are contemplated as would normally occur to one skilled in the art to which the disclosure relates. All limitations of scope should be determined in accordance with and as expressed in the eventual claims of one or more issued patents. 
     Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the subject matter of this disclosure belongs. Although any methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present embodiments, exemplary preferred methods and materials are described. 
     The articles “a” and “an” are used herein to refer to one or to more than one (i.e., to at least one) of the grammatical object of the article. By way of example, “an element” means one element or more than one element. 
     “About” as used herein when referring to a measurable value such as an amount, a temporal duration, and the like, encompasses variations of ±20%, or ±10%, or ±5%, or ±1%, or ±0.1% from the specified value, as such variations are appropriate to prepare the disclosed compositions and perform the disclosed methods. 
     Throughout this disclosure, various aspects of the embodiments are presented in a range format. It should be understood that the description in range format is merely for convenience and brevity and should not be construed as an inflexible limitation on the scope of the embodiments. Accordingly, the description of a range should be considered to have specifically disclosed all the possible subranges as well as individual numerical values within that range. For example, description of a range such as from 1 to 6 should be considered to have specifically disclosed subranges such as from 1 to 2, 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2-5, from 2 to 6, from 3 to 6 and so on, as well as individual numbers within that range, for example, 1, 2, 2.7, 3, 4, 5, 5.3, and 6. This applies regardless of the breadth of the range. 
     The following techniques may be employed in connection with one or more embodiments of the present disclosure. One of ordinary skill in the art, having the benefit of the present disclosure, will appreciate that other known techniques may be employed without departing from the spirit and scope of the present disclosure. 
     Exemplary Method for Preparing Exosomes 
     While at least one exemplary protocol for the manufacture of exosomes is provided herein, one of ordinary skill in the art, having the benefit of the present disclosure, will appreciate that alternative methods for purifying and/or preparing exosomes may be employed without departing from the scope of the present disclosure. Accordingly, the compositions and methods disclosed herein are not necessarily limited to use of the disclosed methods for preparing exosomes. 
     By way of non-limiting example, A-MSC cultures may be scaled from 1 liter to 5 liters and then 30 liters. We evaluate both fed batch and multiple conditioning run methods of culture at 30 liters. The yield is optimized using the final exosomal yield (EVs/ml of conditioned medium) conforming to reference standard criteria. The conformance is checked against release criteria (Table 1). The criteria for success include the quantitative milestones listed below. EVs are purified from the 30 liters of conditioned media using filtration followed by multimodal chromatography. We typically produce at least 5E13 EVs per liter of conditioned media following nutrient supplement deprivation. However, other stressing regimens such as oxidative stress or chemicals are also employed. 
     The following quantitative milestones are assessed. (1) Culture 30 liters of A-MSC cells on microcarriers in bioreactor. The bioreactors may include stirred tank, rocking bed bioreactor, wave bioreactor, packed bed bioreactor, circulation bioreactor or vertical wheel bioreactor. EVs are purified using filtration with the following criteria: (2) Produce EVs with 90% having a size of 100 nm (±80-120 nm). (3) Generate yields of at least 5E13 EVs per L of conditioned media, (4) Contain protein not greater than 12.5 ug protein per ug of EVs, (5) Identify the presence of a lipid bilayer in the EVs using electron microscopy, (6) Detectable presence of a minimum of three of the following EV-specific proteins (CD9, CD63, CD81, TSG101 and Annexin A1) by Western blot (lacking Calreticulin and GAPDH) and (7) Batch to batch variation of not more that 10% based upon the technical feedback from the center for biologics research and evaluation at the FDA. 
     To purify the exosomes in the downstream processing, methods employed include ways to isolate and purify EVs using spiral column filtration, multimodal column chromatography, viral deactivation and polishing rather than the traditional ultracentrifugation process. Spiral column filtration using 500-750 KDa cutoffs is used to concentrate and diafiltrate the conditioned medium. The retentate is chromatographed against anion exchange and size exclusion columns or a bimodal column. Column packing and eluent properties are optimized to improve the yield. The filtrate is filtered through 3-30 KDa dead-end or hollow fiber filter to concentrate the secretome to process further to isolate the growth factors. Acidic pH adjustment (˜2-3.5) is used to deactivate the viruses. Further diafiltration against PBS is included to gain the final product concentration.

     30 liters of culture media of A-MSCs containing at least 1E13 of EV/L is collected and subjected to in-depth filtration series 25 μm, 10 μm, 4 μm, 1 μm, 0.22 μm. The filtrate is concentrated to 600 ml using hollow fiber cartridge filtration (GE) with 500-750 KDa cut-off filters. In order to remove DNA, the concentrated sample (50×) is treated with Benzonase endonuclease. Benzonase endonuclease degrades all nucleic acids down to oligonucleotides of approximately 3 to 5 base pairs in length. These small fragments are removed by next step diafiltration and also can enter into the core of chromatography system where they are bound by the octylamine ligands. The Benzonase endonuclease itself can also be removed by chromatography system. Then, the sample is subjected to 10-times diafiltration using PBS. The diafiltrated sample is chromatographed against a multimodal chromatography resin. 300 ml of resin is packed in a column and equilibrated with PBS. The EV-rich sample (600 ml) is loaded onto the column at a flow rate of 20 ml/min. After running the sample, the column is washed with 300 ml of PBS buffer and then with 0.1M NaOH in 27% 1-propanol as cleaning in place (CIP) solution. The pH of CIP fractions are immediately adjusted to 7.5 with 0.1M HCl in order to analyze the bound proteins. Chromatography column is regenerated with 1M NaOH in 27% 1-propanol solution. 10 ml fractions are collected at each sample loading step to evaluate purified EV and also at elution step to analysis of bounded proteins. Particle size and concentration of EVs are determined via nanoparticle tracking analysis (NTA). Protein quantities in samples are measured using bicinchoninic acid assay kit and RNA concentration are quantified using the RNA assay kit. Western blots are performed in order to test for the presence of surface markers CD9, CD63, CD81, TSG101 and Annexin A1. Image analysis is performed using Image J software. Acidic pH adjustment (3.5) for 1 hour is used to deactivate the viruses. Further diafiltration against PBS is included to gain the final product concentration on a hollow fiber or spiral column filter system. 
     Exosomes may be lyophilized using cryoprotectants and stabilizers such as proteins (peptides), cyclodextrin, or sugars. Process parameters are temperature (deep freeze, −50 to −85° C.), vacuum (50-200 mTorr), and drying time (36-72 h) depending on the solution buffer and exosome concentration. 
     Second Exemplary Method for Preparing Exosomes 
     A-MSC cells are cultured in T-25, T-75 flasks, then transferred to 100 ml bioreactor on Cytodex 1 or 3 microcarriers. The cells are cultured for 7 days in 250 ml and 500 ml bioreactors and conditioned for 2 days. The conditioning regimen included replacing the media with the basal media and removing any supplements and growth factors. After media harvest, the conditioned medium was filtered through 20 um, 10 um, 4 um and 0.22 um filters. The cleared conditioned media was (ultra)-centrifuged at the following: 300 g for 10 min; 2000 g for 20 min; 10,000 g for 30 min; and 100,000 g for 4 h or 120,000 g for 2 h or 150,000 g for 1 h. Then the pellet is resuspended in PBS for storage at −80° C. Alternatively, 750 KDa filtration could be used to prepare the exosomes crude samples and then run the ultracentrifugation step or run Capto Core multimodal chromatography. 
     Exemplary Method of Secretome Preparation. 
     The method for exosome preparation was used with added steps for secretome preparation. The supernatant after ultracentrifugation was passed through 3 KDa filter and the retentate was collected. The concentration ratio ranged from 35 to 50 times the initial volume. 
     Exemplary Methods for Loading of Exosomes with Drugs or Other Components 
     The loading of exosomes with drugs can be achieved with various known methods. The choice of method is often dependent on the physical properties of the drug of interest. For instance, a drug with an overall negative charge may be very difficult to load into exosomes using a passive method because exosomes carry an overall negative charge. 
     Therefore, one or more embodiments of the present disclosure may utilize electroporation to load exosomes with various chemical components. By way of non-limiting example, an electroporation method may be used to load drug(s) or other components into exosomes, but in order to do so, exosomes need to be previously reconstituted and frozen away in Optiprep-free (see recipe below) electroporation buffer. Large numbers (e.g., 5×10 9  to 5×10 10 ) of exosomes are brought to 1× Optiprep using the 2× Optiprep buffer, and the total reaction mix is brought up to 400 ul with drug and 1× Optiprep Electroporation buffer. Note that, in one or mpore embodiments, the required drug volume should be as low as possible such that the buffer is not compromised; if drug volume is excessive, consider using 2× buffer to compensate. 
     Exemplary Electroporation Buffer Recipe: 
     Components 
     3M KCl (Mettler Toledo #63056166), 0.22 um filtered 
     0.5 M Potassium Phosphate, pH 7.2 (Alfa Aesar #J60326), 0.22 um filtered 
     OptiPrep (Stemcell Technologies #07820), sterile 
     Water (Hyclone Molecular Biology Grade), sterile 
     Electroporation Buffer 
     57.5 ul 0.5M K-Phosphate 
     208.3 ul 3M KCl 
     5.25 ml OptiPrep 
     19.45 ml Water 
     Note that this is 1× OptiPrep. When used to reconstitute EVs, one would have to do so with buffer without OptiPrep (OptiPrep should not be frozen); 2× OptiPrep would be required when using your frozen EVs such that the final OptiPrep concentration is 1× in your electroporation buffer. Exemplary electroporation reaction conditions (400 ul total volume) comprise 0.4 cm electroporation cuvettes, 400V, 125 uF. 
     An alternative exemplary method for loading exosomes comprises an incubation protocol. Incubation is a passive method of loading drug into exosomes. Simply, drug and exosomes are suspended together and incubated until loading is maximized. This works well for neutral or positively charged drugs. We have successfully loaded exosomes suspended in DPBS with drug at various temperatures (37° C. and 4° C., for example). Also, loading time may vary, and we have used loading times as low as 5 minutes, and loading times of 18 hours. 
     Yet another exemplary exosome loading protocol may utilize commercially available reagents such as Lipofectamine (ThermoFisher) and Exo-Fect (SBI), which are practical options to use in cases where exosome loading is challenging. Size and/or charge on drugs often makes exosome loading difficult, so using commercial reagents should be kept in mind in such cases. 
     Other exemplary loading methods are available and can be viable options. Methods such as sonication and extrusion are methods used with success. Also, combinations of methods may be utilized, such as, for example, using commercial reagents combined with electroporation.

     Exemplary Composition 6 
     Exosomes released by mouse mast cells exposed to oxidative stress differ in their mRNA content. Exosomes can influence the response of other cells to oxidative stress by providing recipient cells with a resistance against oxidative stress, observed as an attenuated loss of cell viability. Exposure to UV-light affects the biological functions associated with exosomes released under oxidative stress which happens also to the skin cells. Exosomes from bone marrow-derived mesenchymal stem cells (BMSCs) facilitate cell proliferation and survival by transporting various bioactive molecules, including microRNAs (miRs). BMSC-derived exosomes significantly decrease apoptosis rates and reactive oxygen species (ROS) production. A stronger effect is induced by exosomes collected from BMSCs cultured under hypoxic conditions than those collected from BMSCs cultured under normal conditions. Higher miR-214 enrichment in Hypoxic exosomes than in Normoxic exosomes. Mesenchymal stem cell-derived exosomes increase ATP levels, decrease oxidative stress and activate PI3K/Akt pathway. 
     However, the antioxidants released from astrocytes either via extracellular fluid or exosomes to neurons during stress conditions may not be sufficient to provide neuroprotection. Therefore, to combat oxidative stress in the central nervous system, synthetically developed exosomes loaded with antioxidants such as glutathione and the anti-aging protein Klotho may be employed. 
     Oxidative stress induction was simulated using a bioreactor to change the dissolved oxygen (DO %) in the medium. Normal dissolved oxygen (DO %), which ranges from about 30-50% in normoxic culture, was adjusted at 80-100% in oxidative stress induction conditions for varying time periods to evaluate the expression profile in the resulting exosomes, while all other process parameters were maintained at their optimum values. Downstream processes remained the same and the final exosomal and secretome were incorporated into the cosmeceutical preparation.

     Hyperbaric CO 2  induced MSC exosomes (angiogenic factors) MSC exosomes produced in hypoxia situation show different miRNA and protein profiles. The angiogenesis related factors are over-expressed in which different signaling pathways are involved including nuclear factor-kappaB signaling. Several putative paracrine effectors of angiogenesis present in MSC exosomes and increased in expression in MSCs exposed to hypoxia that include platelet derived growth factor, epidermal growth factor, overexpressing Nrf2, fibroblast growth factor, and most notably nuclear factor-kappaB (NFkB) signaling pathway proteins. 
     Overexpression of angiogenesis-related factors may be useful in stimulating vascularization in diabetic patients suffering from diabetic foot ulcer, which is caused by the effects of chronic ischemia, typically due to peripheral artery disease. These angiogenesis-related factors may stimulate pericytes to vascularize the affected tissue. 
     The hyperbaric CO 2  and/or hypoxia conditions were simulated using the bioreactor to change the CO 2 % and/or dissolved oxygen (DO %) in the medium. Normal CO 2 % range is typically about 5-10% during the experiments and/or dissolved oxygen (DO %) which ranged between about 30-50% in normoxic culture was adjusted to about 1-20% in hypoxic conditions. For the hyperbaric CO 2  induction, a range of about 10-40% was applied for varying time periods to evaluate the expression profile in the resulting exosomes, while all other process parameters were maintained at their optimum values. Downstream processes remained the same and the final exosomal and secretome was incorporated into the cosmeceutical preparation.

     Cell Proliferation and Cytotoxicity Assays 
     MTT Assay 
     The BJ Fibroblasts were seeded at 1E4 cells in a 96-well plate in EMEM and 10% FBS in a final volume of 100 ul/well culture medium in a humidified atmosphere (37° C., 5% CO 2 ) and penicillin and streptomycin. The HEK 293 cells were seeded at 1E4 cells in a 96-well plate in DMEM and 10% FBS in a final volume of 100 ul/well culture medium in a humidified atmosphere (37° C., 5% CO 2 ). After two days of culture, A-MSC exosomes and secretome was added to the wells in different concentrations. After different time points, 10 ul of the MTT dye (Sigma Aldrich) was added to each well, and the plate was incubated at 37° C. for 4 h in a humidified atmosphere and under 5% CO 2 . The media content of each well was carefully removed without disturbing cells. Then, 100 μl of DMSO was added to each well and mixed by pipetting up and down. The plate was incubate at 37° C. for 15 minutes. After gentle mixing on a shaker for 1 min, the absorbance of the samples against a background control as blank was measured using a microplate reader (BioMate 5, Thermo Spectronic) at 570 nm. The results are depicted in  FIGS. 5A-5B . 
     WST-1 Assays 
     The BJ Fibroblasts were seeded at 1E4 cells in a 96-well plate in EMEM and 10% FBS in a final volume of 100 ul/well culture medium in a humidified atmosphere (37° C., 5% CO 2 ) and penicillin and streptomycin. The HEK 293 cells were seeded at 1E4 cells in a 96-well plate in DMEM and 10% FBS in a final volume of 100 ul/well culture medium in a humidified atmosphere (37° C., 5% CO 2 ). After two days of culture, A-MSC exosomes and secretome was added to the wells in different concentrations. After different time points, 10 ul of the WST-1 reagent (Roche Applied Science) was added to each well, and the plate was incubated at 37° C. for 2 h in a humidified atmosphere and under 5% CO 2 . After gentle mixing on a shaker for 1 min, the absorbance of the samples against a background control as blank was measured using a microplate reader (BioMate 5, Thermo Spectronic) at 450 nm. The results are depicted in  FIGS. 6A-6D . 
     The results show that different concentration of exosomes and secretome have different effects on the BJ fibroblasts and HEK 293 cells. A concentration dependent cell proliferation and viability effect is observed in the BJ fibroblasts and HEK 293 cells. The lower concentrations of exosomes and secretome did not produce significant improvement in cell proliferation in contrast to E10 concentration. Similar trend is observed in both cell types. However, MTT and WST-1 assays resulted in similar viability profiles. The WST-1 assay shows that the enzymatic activity of the BJ fibroblasts improves by 24.9% in 24 hours while the effect is 62.1% in 48 hours. Similar pattern is observed in HEK 293 cells with 40% after 24 hours against 54.5% in 48 hours. 
     Wound Healing Effect (Scratch Assay) 
     The BJ Fibroblasts were seeded at 5E4 cells in a 24-well plate in EMEM and 10% FBS in a final volume of 1 ml/well culture medium and penicillin and streptomycin in a humidified atmosphere (37° C., 5% CO 2 ). After two days of culture, the plates were exposed to UV light at 365 nm for 10 or 30 minutes using a mini transilluminator machine (BioRad). Then, A-MSC exosomes and secretome was added to the wells in different concentrations. Then a straight scratch was made in each well using a sterile 200 μl pipette tip. At different time points, images of wound scratch were taken under a microscope (Fluorescent, Inverted EVOS FL Life Technologies (Evos)). And scratch areas were analyzed by using Image J (NIH, USA). The results are depicted in  FIG. 7 . 
     Compared to control cells, the migration of fibroblasts into scratched areas of monolayers in the presence of 1E8, 1E9 and 1E10 A-MSC exosomes and 50 ul secretome (40× concentrated) increased by 21.8%, 20.8% and 62.1% after 24 h, respectively.
