Abstract: The present invention provides compositions and methods for treating an osteochondral defect. In one embodiment, provided is a composition for treating an osteochondral defect comprising a biphasic biocompatible matrix and platelet derived growth factor (PDGF), wherein the biphasic biocompatible matrix comprises a scaffolding material and wherein the scaffolding material forms a porous structure comprising an osseous phase and a cartilage phase. In another embodiment, also provided is a method for treating an osteochondral defect in an individual comprising administering to the individual an effective amount of a composition comprising a biphasic biocompatible matrix and PDGF to at least one site of the osteochondral defect, wherein the biphasic biocompatible matrix comprises a scaffolding material and wherein the scaffolding material forms a porous structure comprising an osseous phase and a cartilage phase.

Abstract: The present invention provides compositions and methods for treating deep partial thickness or full thickness wounds or injuries. The present invention also provides compositions and methods for promoting healing and regeneration of impaired or damaged tissue at a site of such partial thickness or full thickness wounds or injuries, as well as promoting vascularization and angiogenesis in regenerating and/or supportive tissue at such sites.

Abstract: The present invention provides compositions and methods for treating full thickness burn injuries. The present invention provides compositions and methods for promoting healing and regeneration of impaired or damaged tissue at a site of such a full thickness burn injury, as well as promoting vascularization and angiogenesis in regenerating tissue at such sites.
