A PVA-GAG-COL composite scaffold is fabricated by polyvinyl alcohol (PVA),glycosaminoglycan (GAG) and collagen (COL).Laser surface modification technology is used to make holes on the surface of the scaffolds.Inside and outside interconnection micro-porous structure is obtained.Biocompatibility test of the scaffolds shows that PVA-GAG-COL scaffold can promote the adhesion and proliferation of the fibroblast.Also,fibroblast can grow normally on the scaffolds with pore diameter from 115 um to 255 um and pore distance from 500 um to 2000 um.PVA-GAG-COL scaffolds possess excellent cell biocompatibility.The porous structure is suitable for cell culture in tissue engineering.
