A Representative images of humanneurons cells stained with the mitochondrial membrane potential sensible fluorescent probe TMRM, the neuronal specific anti-NCAM antibody and the nuclear staining Hoechst. Left panel, basal conditions. Right panel, after addition of the mitochondrial uncoupler FCCP. Scale bar 20 μm. Plot showing the quantification of TMRM fluorescence signal from NCAM+neurons. Data presented as means + SEM of three independent experiments (unpaired, two-tailed t-test).
