Fig. 4. Cortisol-mediated [(Ca²⁺)i] rise involves both intracellular and extracellular Ca²⁺. (a) Representative images of the developing trunk muscle (DTM) loaded with the ratiometric dye FURA-2AM and treated with either vehicle (CONTROL), cortisol (CORT), EGTA, BAPTA-AM or a combination of cortisol with EGTA (EGTA + CORT) or BAPTA-AM (BAPTA-AM + CORT). (b) A bar graph showing the ratiometric intensity at 30 s with extracellular calcium chelator EGTA either with or without cortisol. (c) A bar graph showing the ratiometric intensity at 30 s with an intracellular chelator BAPTA-AM either with or without cortisol. All bars represent mean ± SEM (n = 4–5 independent embryos); bars with different letters are significantly different; one way ANOVA; Holm Sidak post hoc test; p < 0.05. Abbreviations: Ethylene glycol-bis(β-aminoethyl ether)-N,N,N′,N′- tetraacetic acid (EGTA), 1,2-bis(o-aminophenoxy)ethane-N,N,N′,N′-tetraacetic acid-acetoxy methyl ester (BAPTA-AM).
