The induced hmscs-tert were examined by oil red-o staining, alkaline phosphates staining and von kossa staining. results the hmsc-tert was negative for cd34, cd45, cd44, cd106 and cd166. after the induction, accumulated cytoplasmatic red lipid droplets were clearly visible in the adipose cells by oil red o staining, and alkaline phosphates-positive pitchy grains formed in the intracytoplasm and calcium nodes were found by von kossa staining in the osteoblasts.
