A biodegradable microvessel scaffold as a framework to enable vascular support of engineered tissues.

abstract：:Polymethyl methacrylate (PMMA) films were treated by oxygen plasma discharge followed by acrylic acid (AA) grafting. The amount of carboxyl groups introduced by the grafting of AA on to the film surfaces was in the range 0.47-9.48 mumol/cm2, depending on the pressure of the plasma chamber during the discharge treatmen...
