Abstract
In a process for producing a natural implant for tissue of a human or animal body, the body's own cells are multiplied and/or differentiated on a cell base using a culture medium to form the implant.

A process for producing a natural implant for a human or animal body, wherein a body's own cells are multiplied or differentiated on a thin, film-like base using a culture medium to form said implant, said process comprising the steps of:
- a) shaping a porous carrier in at least one surface region according to an external shape of a tissue into which said implant is to be implanted;
- b) placing said film-like cell base on said porous carrier;
- c) applying said body's own cells to said thin, film-like cell base;
- d) covering said thin film-like cell base with a coating material which causes or promotes natural healing, wherein said coating forming a skeleton into which said body's own cells can multiply and spread three-dimensionally to produce said natural implant;
- and
- e) multiplying said cells for forming said implant outside said human or animal body in a perfusion chamber, so that during growing of the implant, said liquid culture medium circulates alone all sides of the implant with said material which causes natural healing selected from the group consisting of fibrin, blood coagulate, extracellular matrix proteins, and combinations thereof.
