We demonstrated that Pluronic P85 at final concentration 0,1-1% was cytotoxic to MSCs. Addition of Pluronic P85 at final concentration 0,001-0,01% increased proliferation of MSCs. Pre-incubation of MSCs with Pluronic P85 increased osteogenic differentiation efficiency of cells.Pluronicmesenchymal stem cellsproliferationosteogenesisdifferentiationПлуроникимезенхимные стволовые клеткипролиферацияостеогенездифференциация[Batrakova E.V., Kabanov A.V.
