Autografts and cultured epidermis in the treatment of vitiligo.
Skin transplants can be a useful and efficacious method to treat vitiligo. The aim is to repopulate areas lacking melanocytes with functional cells taken from normally pigmented areas. Several procedures have been devised and tested: some consist in the simple transfer of epidermis sampled and implanted as is, whereas others are based on the transplantation of disaggregated and manipulated cells. The therapeutic success of the former methods is partly determined by the ability and experience of the surgeon performing the operation, whereas the results of the latter methods mainly depend on the laboratory facilities and abilities of the personnel who manipulate the cells to be transplanted. The transplantation of cultured cells is the most fascinating and promising procedure but requires the observance of still not completely predictable procedures. The use of biological material of animal origin and the use of factors to stimulate cell proliferation, such as growth factors and promoting agents, are other points that require attention.
