Biocompatible perforated membranes, processes for their preparation, their use as a support in the in vitro growth of epithelial cells, the artificial skin obtained in this manner, and its use in skin grafts
First Claim
1. A therapeutic method for treatment of lesions of the body surface which comprises transplantation on said lesions of an artificial skin composed of a biocompatible support membrane consisting of materials of natural, synthetic or semisynthetic origin, and having a thickness of between 10 and 500 μ
- m, which contains an ordered series of holes of a defined and constant size between 10 and 1000 μ
m, separated from each other by a constant distance of between 50 and 1000 μ
m, together with autologous or heterologous epithelial cells in the active proliferation stage present within said holes and on both sides of said membrane.

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