23 Jul Tissue engineering valve
Abstract
The invention discloses a tissue engineering valve, and a preparation method thereof. An acellular dermis matrix is adopted as a biodegradable bracket material for the valve tissue, a vascular endothelial cell and a fibroblast are extracted to serve as seed cells, and the seed cells are cultured and passaged to be planted on the biodegradable bracket material to obtain the tissue engineering valve. The biodegradable bracket material disclosed by the invention is good in biocompatibility, easy for planting cells and can keep the natural structure and the tissue strength of a normal tissue. The tissue engineering valve disclosed by the invention is a living tissue which has a normal valve tissue structure and can be updated and repaired by self. The valve tissue does not have antigenicity and cannot cause immunological rejection reaction.
