title: Effects of Cerium Oxide Nanoparticles on the Proliferation, Osteogenic Differentiation and Adipogenic Differentiation of Primary Mouse Bone Marrow Stromal Cells In Vitro.
abstract: The effects of cerium oxide nanoparticles (nanoceria) on the proliferation, osteogenic and adipogenic differentiation of primary mouse bone marrow stromal cells (BMSCs) were studied by employing 3-(4,5-dimethylthiazol-2-yl)-2,5-dipheny tetrazolium bromide (MTT), alkaline phosphatase (ALP) activity, collagen production, alizarin red-S (ARS) and oil red o stain assays. The results indicated that nanoceria increased the viability of BMSCs at all tested concentrations with evident dose dependence for 24 and 72 h. On day 14, nanoceria inhibited the osteogenic differentiation of BMSCs at all tested concentrations. On day 19 and 24, nanoceria inhibited the formation of mineralized matrix nodules of BMSCs at all tested concentrations. On day 17, nanoceria inhibited the adipogenic differentiation of BMSCs at all tested concentrations. This suggests that the effects of nanoceria on the proliferation, osteogenic differentiation and adipogenic differentiation of BMSCs are very complicated. Both the concentration and culture time have significant influence on the proliferation, osteogenic differentiation and adipogenic differentiation of BMSCs. These results will be helpful for rational applications of nanoceria in the future.
