Fig. 6From: Establishing a deeper understanding of the osteogenic differentiation of monolayer cultured human pluripotent stem cells using novel and detailed analysesThe expression of COL1A1 and OCN in the induced hESCs and hiPSCs. After osteogenic induction for 21 days, 28 days or 35 days, the expression of COL1A1 (red) and OCN (red) in the cell samples were detected by immunofluorescence. The nucleus is blue from DAPI staining. Scale bars,100 μmBack to article page
