Vitamin D Promotes MSC Osteogenic Differentiation Stimulating Cell Adhesion and αVβ3 Expression
mRNA expression of osteogenic markers. qPCR analysis of Coll I, RUNX2, and OPN performed on DBSCs after 12 days of osteogenic differentiation using a medium with vehicle (−) and 1,25(OH)2D3 (+), on PLL-coated surfaces (CTR) or FN-coated surfaces (FN). Expression was normalized to the average of β-actin and β2 microglobulin (B2M) levels for each reaction. and .
