23 Jul Biological artificial blood vessel capable of in vivo capturing endothelial ancestral cell
Abstract
The present invention relates to preparation of biological artificial blood vessel capable of in vivo capturing endothelial ancestral cell, and features that the biological artificial blood vessel may be prepared with composite blood vessel material or homogeneous or heterogeneous blood vessel with the antigen eliminated and through surface modification. The biological artificial blood vessel may be used as tissue engineering blood vessel rack, on which smooth muscle cell and/or endothelial cell may be planted. The biological artificial blood vessel of the present invention has excellent mechanical performance and anticoagulant property, and may be in different calibers. It may be in vivo reshaped and in vivo induced to plant endothelial ancestral cell. It can antagonize intravascular thrombogenesis and inhibit the pathological proliferation of smooth muscle cell to avoid angiostenosis and blood vessel blocking.
