【摘要】BACKGROUND:Cytological studies show that bone marrow mesenchymal stem cel s play an important role in postmenopausal osteoporosis mechanism.
OBJECTIVE:To study the osteogenic differentiation in vitro of bone marrow mesenchymal stem cel s from ovariectomied osteoporotic rats.
METHODS:The osteoporotic animal model was established by performing ovariectomy in the 6-month-old female Sprague-Dawley rats. There were four groups:bone marrow mesenchymal stem cel s control group, bone marrow mesenchymal stem cel s osteoporosis group, bone marrow mesenchymal stem cel s osteogenic induction group and oseogenesis induction group. Bone marrow mesenchymal stem cel s were isolated from the rats of control group and oseogenesis induction group by means of the whole bone marrow adherence method and cultured to the 3rd generation. Then the bone marrow mesenchymal stem cel s were used in al the experiments. Cel morphology was observed under the inverted phase contrast microscope, cel cycle and proliferation index of bone marrow mesenchymal stem cel s were detected by flow cytometry. After osteogenic induction, the expression level of
