23 Jul A method for extracorporally constructing engineering valves of homogeneity biological heart tissue
Abstract
The invention is characterized by using the liquid nitrogen preserved same aorta belt conduit as the bioprosthetic valve cradle, removing endothelial cell on the surface of the valve with 0.1% of SDS, using endothelial cells originated adult marrow mesenchyma stem cell through external directional evoked differentiation as planting cells, planting onto the valve cradle, static state culturing 20 days, carrying out 0.5% silver nitrate coloration and scanning electron microscopic observation, radiography, so as to determine the endothelium degree.
