摘要

The invention relates to biocompatible membranes constructed of materials of natural, synthetic or semisynthetic origin, and having a thickness of between 10 and 500 mu , characterised by containing an ordered series of holes of a constant size between 10 and 1000 mu , separated from each other by a constant distance of between 50 and 1000 mu , and obtained by perforation by mechanical, thermal laser or ultraviolet radiation means, they being suitable for use as a support for the in vitro growth of epithelial cells, the invention also relating to the artificial skin obtained thereby and its use in grafts.
