Acheron function in zebrafish myogenesis. (A–C) Lateral views of 24 hours postfertilization (hpf) zebrafish embryos labeled with the F59 antibody to reveal slow twitch muscle fibers, white lines show extent of one somite (S). achn mRNA injected embryos (B) had well formed slow fibers (red) and slightly larger somites than seen in uninjected control embryos (A). achn MO injected embryos (C) had reduced somites with less organized slow fibers. (D,F and H) Trunk cross-sections of 48 hpf embryos. achn mRNA injected embryos (F) had larger somites than uninjected embryos (D) with well formed fast fibers throughout the trunk. In contrast, achn MO injected embryos (H) had highly reduced somites with poorly formed fibers. (E,G and I) Confocal images of To-Pro3 stained 48 hpf embryo cross-sections. Left somite is outlined. achn mRNA injection (G) led to a decrease in nuclei. In contrast, ach MO injected embryos (I) had more nuclei despite having smaller somites. (J) Mean diameter (μm) of slow twitch fibers in uninjected, achn mRNA injected, and achn MO-injected embryos. Error bars indicate SEM. (K) Mean number of To-Pro3 labeled nuclei in somite regions of 12 μm sections. Error bars indicate SEM. In A-C scale bar = 20 μm, D–I scale bar = 50 μm. DIC, differential interference contrast microscopy; S, somite.
