The rat bone marrow mesenchymal stem cells（BMMSCs） were obtained from bone marrow and purified.BMMSCs were co-cultured with our synthesized composite: arginine-glycine-aspatic acid（RGD） peptide modification of poly {（lactic acid）-co-[（glycolic acid）-alt-（L-lysine）]}/poly（D,L-lactic acid）/β-tricalcium phosphate/nerve growth factor（PRGD/PDLLA/β-TCP/NGF）.Observed under scanning electron microscope,most BMMSCs showed spindle-shaped on the surface of PRGD/PDLLA/β-TCP/NGF composite,which is close to the primary culture condition of BMMSCs.The result indicates that PDLLA/PRGD/β-TCP/NGF composite has excellent cellular affinity and shows promising potentials in the fabrication of nerve tissue engineering scaffold.BMMSCs on PRGD/PDLLA/β-TCP/NGF composite exhibited good growth condition.
