In present study, a previously fabricated tripolymer composite scaffold of PCL/gelatin/chitosan was modified with collagen I and the modified scaffold were studied for biocompatibility of L929 mouse fibroblasts and human osteoblast cells. Phase contrast microscopy confirmed the viability of L929 mouse fibroblasts and human osteoblasts cultured with the modified composite scaffold which indicated that scaffold did not produce any toxic effect on both cells. |
