Fig. 4

Mef2ca^+/⁻;mef2cb^−/−mutant embryos show reduced ventricular size compared to siblings. (A) Confocal images of 3 dpf (top panels) or 5 dpf hearts (bottom panels) from a cross of mef2ca^+/⁻;mef2cb^+/⁻;Tg(myl7:EGFP) to either mef2ca^+/+;mef2cb^+/⁻;Tg(myl7:EGFP) or mef2ca^+/⁻;mef2cb^+/+;Tg(myl7:EGFP) fish. mef2ca^+/⁻;mef2cb^−/⁻ embryos have a smaller heart at 3 and 5 dpf. Scale bars = 50 μm. (B,C) Volume, trabecular length and width were quantified for embryos from crosses in A designed to test Mef2ca (B) and Mef2cb (C) function. One-way ANOVA analysis followed by Bonferroni post hoc tests, p-values indicated on graphs. Graphs show mean ± S.E.M. N for each group shown on bars.
