| abstract |
The invention proposes a cell-free graft, comprising (i) a cohesive, structure-forming matrix with open porosity made from a biologically and pharmaceutically acceptable material and (ii) serum. In one particularly preferred embodiment, the matrix additionally contains a gel. By virtue of a second aspect, a method of producing such a cell-free graft is proposed, whereby the matrix and the gel, if one is provided, is placed in contact with the serum. The graft may optionally be dried with serum. Alternatively, the matrix and the gel, if one is provided, are in the dried state before being placed in contact with the serum. By virtue of a third aspect, finally, the invention proposes the use of the cell-free graft for regenerating tissue and in particular for regenerating cartilage and/or bone. |
