Provided herein are methods which alter the mechanical and biological properties of polymeric materials. Also provided are compositions comprising the polymeric materials having said properties.

The present invention concerns a cell-enriched fat graft and methods of making and using the same. The present invention also provides a kit for making and using the cell-enriched fat graft of invention.

A method for producing a regenerative organ germ for transplantation includes using regenerative organ germ for transplantation ensuring continuity with a recipient after transplantation and facilitating transplantation procedures. A method for producing a regenerative organ germ provided with a guide for transplantation includes preparing a regenerative organ germ by closely contacting a first cell mass, which substantially consists of mesenchymal cells, and a second cell mass, which substantially consists of epithelial cells, culturing these cell masses within a support, and inserting the guide into the regenerative organ germ.

Compositions containing purified collagen biomaterial derived from tissues, for example, insoluble amnion, soluble amnion, soluble chorion of the human placenta, are provided. The collagen compositions can be used to promote wound healing, promote tissue regeneration, prevent or reduce scarring, reduce local inflammation, minimize tissue rejection, promote graft integration. Methods for using the collagen composition as a biomaterial implant for dermal filling, skin grafting, and hair transplantation are also provided.

The present invention concerns a cell-enriched fat graft and methods of making and using the same. The present invention also provides a kit for making and using the cell-enriched fat graft of invention.

The formation of scars at a wound site is reduced by contacting the wound site with an effective dose of an inhibitor of focal adhesion kinase (FAK) formulated in a pullulan hydrogel The release profile of the FAK inhibitor can be adjusted according to the nature of the wound, e.g., excisional wounds, burn wounds, etc.

Compositions and methods for producing reconstituted human skin and/or hair follicles in situ are provided. The method for producing the skin is unique in that tissue culture expanded cells including multipotent cells such as neonatal cells as well as cultured epidermal and dermal cells are immediately placed on a substrate such as a membrane and then the membrane with adherent cells is placed on a skin wound. Examples demonstrate formation of hair follicles in situ.
