Tissue-engineered skin substitutes in regenerative medicine.
Recent advance in cellular tissue-engineered skin constructs have refined the applications already commercially available, in particular, by the use of genetically modified cells to enhance their properties on the treatment of wounds and to ease the application of epidermis using sprayed keratinocytes. This approach lends itself to use of chimeric epidermis, cultured allogeneic cells, to provide short-term coverage, together with minimally cultured autologous cells for long-term repair. Experimental models of skin include pathological conditions, phenomena such as aging and organogenesis, as in the hair follicle grown from isolated cells in vitro. The recent development of induced pluripotent stem cells raises the possibility of realizing the dream of skin and even limb regeneration shown by animals such as the salamander.
