Objective To investigate the effects of carbon monoxide releasing molecule-3( CORM-3) on the osteogenic differentiation of rat bone marrow-derived mesenchymal stem cells( BMSCs). Methods The BMSCs were divided into 2 groups,group A and group B. Group A was subdivided into osteogenic group,100 μmol/L CORM-3 group,200 μmol/L CORM-3 group,400 μmol/L CORM-3 group and control group. Group B was subdivided into osteogenicgroup,100 μmol/L CORM-3-osteogenic group,200 μmol/L CORM-3-osteogenic group,400 μmol/L CORM-3...
