Fig. 4From: Black Phosphorus Nanoparticles Promote Osteogenic Differentiation of EMSCs Through Upregulated TG2 ExpressionThe evaluation of cell proliferation of the BPs-treated group. EMSCs were treated with BPs (0, 2, and 4 μg/ml) for 24 h. Cell proliferation was measured by immunofluorescent staining with anti-Ki67 antibody (red) and DAPI (blue), and merged images were shown (A–C). Ki67-positive cells among 4′,6-diamidino-2-phenylindole (DAPI)-positive cells were counted in two high-power fields in each of three plates. Data are expressed as the mean ± SD (D).Back to article page
