ABSTRACT:
A cultured skin and a grafting cultured skin sheet are provided, each of which is a cultured reconstructive skin with a high take rate using cells collectable from cells originated from tissue included in an umbilical cord such as tissue included in an umbilical cord originated from a human fetus. The grafting cultured skin stratified sheet is prepared by placing an epithelium sheet on the top surface of a cultured dermis. The cultured dermis includes as components a cultured skin containing cells originated from a tissue included in an umbilical cord, such as umbilical cells, more concretely, umbilical fibroblast cells, being separated and cultured, preferably in a collagen nonwoven fabric. On the other hand, the epithelium sheet is prepared by culturing and stratifying the umbilical cord epithelium cells.
