| Abstract: | Argon plasma treatment was used to improve the biocompatibility of the surface of photo-polymerization poly(ethylence glycol) diacrylate(PEGDA)/2-hydroxyethyl methacrylate(HEMA) hydrogel.The adhesion and proliferation of bone marrow mesenchymal stem cells(BMSCs) on the surface of the films was investigated.The surface structures of the PEGDA-based films before and after treated by Ar plasma were characte-{rized} by scanning electron microscope(SEM),X-ray photoelectron spectroscopy(XPS) and contact angle.The... |
