Abstract (en)
[origin: WO9420151A1] The process attempts to produce especially cargilage cells in vitro. The cells are placed in a three-dimensional supporting structure, preferably of a polymer nonwoven, with the shape of the supporting structure corresponding to that of the implant to be obtained. The supporting structure is then perfused with a nourishing solution for a long period so that the intercellular matrix bonding the cells together can form at least partially within the supporting structure. The supporting structure with the at least partially formed intercellular matrix is then implanted. On the subsequent resorption of the supporting structure, the shape of the implant is preserved thanks to the intercellular matrix then formed.
