Abstract: A method for the in vitro detection of cartilage tissue and/or for the in vitro determination of the purity of cartilage tissue includes: a) treating a tissue sample with a protease and b) testing the protease-treated tissue sample for the presence of protease-resistant fragments of type II collagen and/or type I collagen. Methods can be carried out for preparing a cartilage cell culture, and for preparing a cartilage cell-loaded implant. Protease-resistant fragments of type II collagen and/or type I collagen can be used for the in vitro detection of cartilage tissue and/or for the in vitro determination of the purity of cartilage tissue. A kit can be used for carrying out the methods.

Abstract: Disclosed is a multi-chamber applicator comprising an aqueous gelatin solution and an aqueous cross-linking agent solution in separate chambers.

Abstract: The invention relates to the use of gelatin and a cross-linking agent to provide a medical glue which forms a cross-linked gelatin gel in an area of application of the human or animal body. According to the invention, (i) the gelatin and the cross-linking agent are mixed with each other to form the cross-linking medical glue which is then administered to the area of application; or (ii) the gelatin and the cross-linking agent are made available in separate form and are administered, simultaneously or one after the other, to the area of application while forming the cross-linking medical glue.

Abstract: To improve a cartilage replacement implant for the biological regeneration of a damaged cartilage area of articular cartilage in the human body, comprising a cell carrier which has a defect-contacting surface for placement on the damaged cartilage area and is formed and designed for colonization with human cells, so that after implantation of the cartilage replacement implant, formation of a gap between adjacent contact surfaces of the implant and surrounding recipient tissue is minimized, it is proposed that the cell carrier rest with surface-to-surface contact on a carrier and be joined to the carrier at a cell carrier surface that faces away from the defect-contacting surface. A method for producing a cartilage replacement implant is also proposed.

Abstract: The present invention relates to a composite biomaterial and a process for producing a composite biomaterial with controlled release of active ingredients, comprising a three-dimensional polymer-based support structure, and a polymer-based matrix structure. The active ingredients are in this case incorporated into the composite biomaterial via the matrix structure, and the composite biomaterial is obtainable by introducing the matrix structure into the support structure. The active ingredients may in this case be incorporated for example adhesively, via specific binder molecules or via enzyme-labile linker molecules via the matrix structure into the composite biomaterial.
