Abstract: A method of decellularizing in an animal tissue includes digesting the animal tissue; treating the animal tissue with a surfactant: treating the animal tissue with at least one zwitterionic detergent to form a decellularized animal tissue; and treating the decellularized animal tissue with at least one advanced glycation end-product (AGE) inhibitor to reduce AGE crosslinking in the decellularized animal tissue. The decellularized animal tissue may be ground into a powder and dissolved in a digest solution to form a bioink composition useful for 3D printing an in vitro model of healthy or diseased tissue.

Abstract: Provided herein is a copper-free, non-toxic click hydrogel that exhibits minimal swelling. The hydrogel may be used as a sealant and/or as a delivery vehicle for local administration of substances of interest, such as therapeutic agents.

Abstract: Inflammatory processes, particularly those arising from trauma or injury to the region of a bone joint, are causative of osteoarthritis (OA). A composition comprising microRNA-122, microRNA-122 mimic, and/or an inhibitor of microRNA-451 reduces or inhibits inflammatory mediators in articular chondrocytes and related cells. When administered to a subject at risk of developing OA, development of OA and/or progression of OA disease are inhibited, and cartilaginous structures are preserved in the joint. Since joint injury is associated with subsequent development of OA, the treatment is particularly suitable following an acute injury to a joint.

Abstract: Compositions and methods are described for a polymer hydrogel created by a cycloaddition reaction between an azide and an alkyne that proceeds rapidly without catalyst to produce the polymer hydrogel in less than ninety seconds. The polymer hydrogel can be used in in vivo applications for the localized delivery of therapeutic agent in aqueous solutions. An example of therapeutic delivery of a protein in a mouse model is demonstrated.

Abstract: Provided herein according to some embodiments of the invention are methods of inhibiting or preventing calcification of hydrogels. Such methods may include combining the hydrogel with a buffer solution having a pH lower than 7.4; forming a hydrogel by crosslinking alginate in a solution comprising a bisphosphonate compound; and/or forming a hydrogel by crosslinking a polyanionic polymer with a polyvalent cation that is not Ca2+. Compositions that may be used in such methods are also provided herein. Also provided herein according to some embodiments of the invention are methods of bone regeneration and/or formation that include administering a hydrogel that does not encapsulate biological material that affects calcification and/or bone formation to an area of a subject's body that is in need of bone formation and/or regeneration.

Abstract: Provided according to embodiments of the invention are methods of manufacturing implant devices. In methods described herein, implant devices are exposed to a reactive gas that includes a reactive species, and optionally, an inert gas, at elevated temperatures, for a duration sufficient to generate a high density of nanoscale structures on the exposed surface of the device. Also provided are implant devices formed by methods described herein.
