| Objective: To investigate the method for isolation and amplification of the bone mesenchymal stem cells (BMSCs) in
vitro and to identified it. Methods: Male SD rats around 100g, the bone marrow cells were obtained from hind femur and tibia, whole
bone marrow primary culture, purified by repeated passage in vitro amplification. Cell morphology was observed, and expressions of
CD34, CD90, CD105 cell factors were examined by flow cytometry, to identify whether it's the BMSCs. Results: Cells appeared spindle-
shaped and showed characteristic swirling growth. The surface marker CD34 was negative, CD90, CD105 were positive. Conclusion:
We successfully isolated the bone marrow mesenchymal stem cells (BMSCs) by the whole bone marrow culture method, and found that
cells had high purity and good activity within 10th generation. The whole bone marrow culture was simple and easy. |
