Effects of oncostatin M on cell proliferation and osteogenic differentiation in C3H10T1/2.

To explore the effects of protein factor Oncostatin M (OSM), a member of the Interleukin-6 (IL-6) family on cell proliferation, osteogenic differentiation and mineralization.Basal nutrient solutions of different concentrations of OSM (0, 5, 10, 20, 40, 80 ng/ml) were used. In order to divide embryonic origin between mesenchymal stem cells C3H10T1/2 of in vitro cultured mice, and the effects of in vitro proliferation efficiencies of C3H10T1/2 cells of different concentrations of OSM, the C3H10T1/2 cells were divided into four groups: (1) Basal nutrient solution group (negative control); (2) Osteogenesis induced liquid group (positive control); (3) OSM (20 ng/ml) group; (4) Experimental group (osteogenesis induced liquid + OSM (20 ng/ml)). The expressions levels of relevant osteogenesis and mineralization genes were detected.OSM had several effects on promoting the proliferation of embryonic origin mesenchymal stem cells C3H10T1/2 with respect to time of exposure as well as concentrations. In the present study, it has been shown that when the concentration of OSM is 20 ng/ml, the effects of promoting proliferation are most obvious. OSM can induce osteogenic differentiation of C3H10T1/2, make the process of osteogenic differentiation in advance, and promote the formation of end-stage calcium deposits and mineralized nodule, and osteogenic differentiation of C3H10T1/2 is finally achieved.OSM can promote the proliferation of C3H10T1/2, and induce its osteogenic differentiation and end-stage mineralization.
