چکیده
In the present study, we investigated the combined effect of Colla Cornus Cervi (CCC) and BMP7overexpressing bone marrow-derived mesenchymal stem cells (BMSCs) on osteogenic induction and the treatment of avascular necrosis of the femoral head (ANFH). BMSCs were isolated from rats. BMP7-overexpressing BMSCs were generated by lentiviral-mediated gene transduction. Cell proliferation, alkaline phosphatase (ALP) activity, osteogenesis related gene expression, osteocalcin levels, and calcified nodules were quantified and compared between four groups: untreated controls, BMSCs cultured with CCC complex medium, BMP7overexpressing BMSCs, and BMP7-overexpressing BMSCs cultured with CCC complex medium (CCC+BMP7). CCC+BMP7 BMSCs showed higher proliferation rate. ALP activity and osteaocalcin content were significantly increased in CCC+BMP7 BMSCs. The osteogenesis related genes, COLI, and integrin-α2, -α5, and -fl1, were expressed significantly higher in CCC+BMP7 BMSCs. The number of calcified nodules in the CCC+BMP7 group was significantly higher than that in other groups. For in vivo assays, ANFH was induced in rats, and BMSCs were injected into the femoral head of the lower left extremity. In rats with induced ANFH, general observation scores of the CCC+BMP7 injected group were significantly higher than the model group. X-ray and microscopic observations revealed that ANFH was significantly improved and femoral head cells gradually recovered in rats treated with CCC+BMP7 BMSCs. Our results suggest that CCC+BMP7 significantly promote the proliferation and osteogenic differentiation of BMSCs in vitro. CCC+BMP7 BMSCs promote the ability of repairing ANFH in rats, providing a new therapeutic paradigm for the treatment of ANFH.

متن کاملFoxc2 regulates osteogenesis and angiogenesis of bone marrow mesenchymal stem cells
BACKGROUND The Forkhead/Fox transcription factor Foxc2 is a critical regulator of osteogenesis and angiogenesis of cells. Bone marrow mesenchymal stem cells (BMSCs) have the capacity to differentiate into osteoblasts, chondrocytes, adipocytes, myocytes and fibroblasts. The present study investigates the role of Foxc2 overexpression in osteogenesis and angiogenesis of BMSCs in vitro. METHODS B...
