The invention relates to an injectable hydrogel composition of 10 wt % gelatin, 0.5-2 wt % hyaluronic acid, 0.5-1.0 wt % genipin and an aqueous medium. The composition exhibits high biocompatibility, injectability and in-situ gelation ability at bone defect sites. The composition is suitable for serving as an osteogenic scaffold for cell adhesion and as an osteogenic carrier for delivering beneficial substance for promoting bone regeneration. The invention also relates to a medical formulation comprising the injectable hydrogel composition in combination with an osteogenic substance, as well as the medical use thereof in the treatment of segmental bone defect.

The present disclosure is drawn to compositions and methods of making and using lyophilized platelet lysates. Specifically, a method of preparing a composition suitable for therapeutic use or as a culture medium can comprise steps of concentrating platelets from a platelet source to form a platelet rich portion of the platelet source, and lysing the platelets in the platelet rich portion to form a plurality of lysates. An additional step includes lyophilizing the lysates to form lyophilized platelet lysates in a composition with released concentrations of available growth factors, cytokines, and chemokines. In one example, at 30%, by platelet count, of platelets from a platelet source can be lysed using this process.

A method for treating a medical implant uses plasma polymerization to apply a coating At least one treatment parameter is selected so that the reactive chemical groups of the coating are chemically modified to prevent an adsorption of interfering substances into the coating. An implant includes a plasma polymer coating that is biocompatible, and includes a antibiotically acting metal. The coating is free from aldehyde groups

This invention includes malleable, biodegradable, fibrous compositions for application to a tissue site in order to promote or facilitate new tissue growth. One aspect of this invention is a fibrous component that provides unique mechanical and physical properties. The invention may be created by providing a vessel containing a slurry, said slurry comprising a plurality of natural or synthetic polymer fibers and at least one suspension fluid, wherein the polymer fibers are substantially evenly dispersed and randomly oriented throughout the volume of the suspension fluid; applying a force, e.g., centrifugal, to said vessel containing said slurry, whereupon said force serves to cause said polymer fibers to migrate through the suspension fluid and amass at a furthest extent of the vessel, forming a polymer material, with said polymer material comprising polymer fibers of sufficient length and sufficiently viscous, interlaced, or interlocked to retard dissociation of said polymer fibers.

A composite bone graft which comprises an allograft bone component; a synthetic bone substitute, wherein the synthetic bone substitute is in contact with the allograft bone component. The composite is arranged within a resorbable mesh casing.

The present invention provides methods and compositions useful in the regeneration of damaged, lost and/or degenerated tissue in humans and animals. In certain embodiments, the present invention provides an acellular bioabsorbable tissue regeneration matrix, methods of making such a matrix, and methods of using such a matrix for the regeneration of damaged, lost and/or degenerated tissue. In certain embodiments, methods and compositions of the present invention are useful in the treatment of damaged, lost and/or degenerated nerve tissue.

The present disclosure provides a method and a kit for inducing growth or regeneration of a damaged connective tissue of a subject, or the treatment thereof by applying a clot of blood that is withdrawn from the subject. The connective tissue can be tendon. By one implementation of the present invention, the blood that is withdrawn from the subject is introduced to a lumen of a connective tissue enveloping hollowed element that envelopes the damaged portion of the connective tissue while controllably coagulating it within the lumen to form a clot on the damaged portion of the connective tissue. e.g. by mixing it with coagulation initiators shortly prior to the introduction of the blood into the lumen. The clot, while in physical contact with the damaged portion of the connective tissue, enhances the rehabilitation of the connective tissue and may partially or fully restore its functionality.
