Fig. 3From: Black Phosphorus Nanoparticles Promote Osteogenic Differentiation of EMSCs Through Upregulated TG2 ExpressionThe cytotoxicity of BPs. Cells were treated with BPs (0, 2, 4, 8, 16, 32, 64,128, 256, and 512 µg/ml) for 24 h, and EMSC viability was tested by cell counting kit (CCK-8) proliferation assay (n = 9). Data were expressed as mean ± standard deviation (SD). **p < 0.01.Back to article page
