Skin replacement using collagen extracted from bovine hide.
This paper reviews the use of biological sponge-shape matrices as dermal replacements in order to orient newly formed wound tissue. Sponge-shape matrices consist of a scaffold made of cross-linked collagen extracted from bovine hide.  Other molecules with specific activities on wound tissue ingrowth are bound to collagen.  The lamination of sponge with a synthetic material allows this device to be implanted as a temporary skin substitute.  For the epidermal cell layer replacement, a biological film-shape matrix can be used in order to cultivate autologous cells during the period that biological sponge-shape matrices are invaded by wound tissue.
