Abstract
The present invention relates to a method for preparation of an artificial blood vessel using a tube-type porous biodegradable scaffold having a double layered structure and a stem cell, and an artificial blood vessel made by the same. Specifically, the present invention relates to a method for preparation of an artificial blood vessel by separately seeding a stem cell onto the inner membrane and an outer membrane of a tube-type porous biodegradable scaffold having a double layered structure, wherein the inner membrane and the outer membrane having different biodegradable polymer nano-fiber arrangements are continuously linked, and by inducing differentiation; and an artificial blood vessel made by the same.
