||1:To make artificial blood vessels the team took smooth-muscle cells from fresh corpses and cultured them on tubular scaffolds made of a material called polyglycolic acid.||2:Grown this way, smooth muscle secretes collagen, a structural protein that is, among several other things in the body, an important component of the walls of blood vessels.||3:The polyglycolic acid degrades spontaneously over the course of a few weeks with the consequence that it is, in effect, replaced by the collagen.||4:The result is a tube of the length and diameter of the original scaffold, that is composed of collagen and smooth-muscle cells—a structure similar to a natural blood vessel.
