First Claim
Patent Images
1. A process for preparing artificial skin, comprising:
- a) perforating, via a screening system using a mechanical or laser perforation device, a continuous biocompatible membrane that can support the in vitro cultivation of epithelial cells comprising a natural, synthetic, or semisynthetic material having a thickness of between 10 and 500 μ
m thereby obtains an ordered series of holes having a diameter between 10 and 1000 μ
m, separated from each other by a constant distance of between 50 and 1000 μ
m, wherein epithelial cells can be cultured in vitro within said holes and on both sides of said membrane, andb) seeding said perforated biocompatible membrane of step a) with autologous or heterologous epithelial cells in the active proliferation stage and cultivating said epithelial cells thereon in vitro.

Abstract
The invention relates to biocompatible membranes constructed of materials of natural, synthetic or semisynthetic origin, and having a thickness of between 10 and 500 μ, characterised by containing an ordered series of holes of a constant size between 10 and 1000 μ, separated from each other by a constant distance of between 50 and 1000 μ, 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.
