The present study established a non-contact coculture system in vitro, aiming to investigate the crosstalk between human dental pulp stem cells (hDPSCs) and human umbilical cord mesenchymal stem cells (hUCMSCs) on proliferation activity and osteogenic genes expression through paracrine. | The crosstalk between HDPSCs and HUCMSCs on proliferation and osteogenic genes expression in coculture system
