Fig. 5From: Combination of the BeWo b30 placental transport model and the embryonic stem cell test to assess the potential developmental toxicity of silver nanoparticlesConcentration–response curves for cytotoxicity towards mESCs and for the effect on differentiation into contracting cardiomyocytes of: a (LA) AgNPs, b (Cit) AgNPs, c (BEPI) AgNPs, d (Ag2S) NPs, and e AgNO3. The viability of mESCs (right y-axis) was assessed using the ATPlite assay after 24 h and 120 h of exposure. The differentiation of mESCs into contracting cardiomyocytes (left y-axis) was scored after microscopical evaluation. Values are given as a percentage of the control (mean ± SD; n = 3)Back to article page
