Fig. 2: SSRIs toxicity on differentiating cardiomyocytes.

a The procedure of SSRIs treatment on differentiating cardiomyocytes. b The identification of NOAEL of three SSRIs during the entire differentiation process of H1-CMs. c The ATP production of differentiating H1-CMs after SSRIs exposure (n = 8 biological replicates). d The mitochondrial membrane potential of differentiating H1-CMs after SSRIs exposure (n = 7 biological replicates). e–i The mitochondrial respiration levels of differentiating H1-CMs after SSRIs exposure. e Graphical representation of the mitochondrial stress test. f basal respiration, g maximal respiration, h spare respiration capacity, i ATP respiration. *indicates p < 0.05, **indicates p < 0.01, ***indicates p < 0.001, ****indicates p < 0.0001. n = 5 biological replicates for DMSO and Sertraline groups; n = 7 for Fluoxetine and Paroxetine groups.
