Abstract
A method for modifying surface of biodegradable porous polymer scaffold for tissue engineering using a low temperature plasma discharge apparatus, and particularly, a method for inducing the biodegradable porous polymer scaffold to be hydrophilic by graft polymerizing a hydrophilic monomer on the surface of the biodegradable porous polymer scaffold, which is made of polylactic acid, polyglycolic acid or poly(lactic acid-glycolic acid) copolymer, using a low temperature plasma. The surface-modified porous polymer scaffold according to the present invention has an enhanced cell compatibility in cell culture in vitro, and promote tissue growth when the cell is transplanted into a body.
