Figure 4

Frequency of spontaneous contractions and Ca²⁺ transients in the trunk of zebrafish embryos (24–28 hpf). (A) Representative experiments showing contractions (measured by transmission light, upper panels) and Ca²⁺ transients (measured by bioluminescence, lower panels) in the same embryo expressing GA (left) or mitoGA (right). (B) Comparison between the average frequency of contractions observed by transmitted light (imaging at 4.2 Hz) and Ca²⁺ transients (imaging at 4.7 Hz) in the cytoplasm (GA, left) and mitochondria (mitoGA, right). A two-tailed paired t-test was used. Shown as mean ± SEM (n = 6 embryos).
