Rab38s expression pattern during zebrafish embryogenesis. Rab38a is expressed across the pharyngula embryonic period (24–48 hpf) (a-d): at 24 hpf there is a faint signal in RPE (arrowhead) and a strong one in migrating melanoblasts (a, b, white arrowhead) and a low level of expression is detectable in the mid-ventral region of brain (a); at 48 hpf the expression is visible only in the RPE (black arrowhead) (c, d). Rab38b is expressed only at late developmental stages (e-h): at 48 hpf in a small region of the pharyngeal arches (white arrow) and in the developing swim bladder (e, f, white asterisks), while at 72 hpf only in swim bladder (g, h, white asterisks). The gene Rab38c gene is strongly expressed in the head region (i and j for 24 hpf larvae). Lateral view in all images (anterior is on the left) except d and f that are ventral (anterior on the top)
