Knockdown of YTHDF1 compromised osteogenic differentiation of hBMSCs in vitro. (a) The expression of osteogenic markers (RUNX2, ALP, COL1A1, and osterix) was evaluted by qRT–PCR 3 days after osteogenic culture of hBMSCs knocked down by siYTHDF1. (b) Western blot analysis of osteogenic markers (RUNX2, COL1a1, and SP7) on Days 1 and 3 of osteogenic differentiation of hBMSCs. (c) Alkaline phosphatase activity was evaluated by ALP staining at Day 5 of osteogenic differentiation. Scale bar: 200 μm. (d) Mineral deposits were determined by ARS staining on Day 14 of osteogenic differentiation. Scale bar: 200 μm. (e) Immunofluorescence staining for the COL1A1 and RUNX2 protein after 3 days of osteogenesis. Scale bar: 200 μm. and compared to the control group.
