【Abstract】 Objective To study the replant time for compound of bone marrow stromal cells (BMSCs) and coral.Methods After osteogenicly induced,BMSCs were added to and compounded with coral.Under scanning electron microscopy and inverted microscopy,the compound cultured in vitro were observed at the time points of 1,3,5,7 day,and the compound were replanted subcutaneously in nude mice.Result BMSCs got a better compound with coral at the time point of 3rd day,and the new bone was formed in vivo.Conclusion It was at 3rd day of the cultured time point in vitro that compound of BMSCs and coral could be replanted in vivo.更多还原
