Abstract

A method for preparing tissue for medical applications, in particular tissue for use for an artificial heart valve, wherein the method has the steps of decellularizing the tissue by means of a detergent and subsequently cross-linking the collagen fibers of the tissue by means of a suitable cross-linking agent. At least one lipopeptide, such as surfactin, for example, is used as the detergent for decellularization.
