Low-Dose Methylmercury-Induced Apoptosis and Mitochondrial DNA Mutation in Human Embryonic Neural Progenitor Cells

Figure 5

The effect of MeHg on mitochondrial membrane potential in hNPCs. (a) Fluorescence microscopic image of JC-1 signal after MeHg treatment. Images represent typical results of one out of three independent experiments. (b) Mitochondrial membrane potential () was calculated by the ratio of JC-1 incorporation into mitochondria. Results are expressed as means ± SEM (). when compared with the corresponding control group (dose: 0 nM).
