Fig. 3 Expression of Pax2/5/8 genes at the midbrain-hindbrain boundary of zebrafish embryos. Transcripts of Pax2.1 (A,E), Pax2.2 (B,F), Pax5 (C,G) and Pax8 (D,H) were detected by whole-mount in situ hybridization in embryos from 10 hours (bud stage) to 27 hours postfertilization. Embryos are shown in lateral view (B-H) except for the bud stage (A) which is a dorsal view. cb, cerebellum; h, hindbrain; mhb, midbrainhindbrain boundary; na, (pro)nephric anlage; nd, nephric duct; pn, pronephros; os, optic stalk; otp, otic placode; otv, otic vesicle; ov, optic vesicle; ret, retina; som, somite; sc, spinal cord; tec, tectum; tg, tegmentum.
