Abstract:
Objective To discuss a new method of BMSCs culture which can reduce the lead-in of extraneous antigenic substances in the process of cell culture, and can thus better meet the demand on the quantity and biological characteristics of BMSCs in the clinical use of tissue engineering bone. Methods BMSCs from a human adult in vitro were induced by using autologous platelet-rich plasma instead of animal serum in high-carbohydrate DMEM (Dulbecco's minimum essential medium). After the cultured BMSCs were amplified rapidly by Rotary Cell Culture System, their growth status was observed and their biological characteristics were detected. Results The cells were in good growth status and presented fine biological characteristics. Their growth speed in Rotary Cell Culture System was observed to be evidently faster than that by conventional methods. Conclusions Rotary Cell Culture System by autologous platelet-rich plasma instead of animal serum is a good culture method to induce human BMSCs in vitro. The quantity and biological characteristics of BMSCs cultured in this way can meet the demand in clinical use.
