Collagen is a natural part of the bone composition, and collagen membranes are in use to support bone regeneration. However, these membranes are based on collagen, which is completely dissolved before it is further processed to a membrane, and consequently has completely lost its natural structure and consequentyl some important biological functions. Researchers of the University of Bielefeld have found a method to prepare collagen type I in its natural pore-like structure. They have shown that cultivation of human inferior turbinate stem cells (ITSCs) on collagen fibrils prepared by that method show osteogenic differentiation. Therefore, this collagen preparation method can be used for multiple applications in regenerative medicine, e.g. in bone fractures after accidents, joint replacement, dental prothesis, or plastic surgery.
The invention is offered for licensing and further development.
