Fig. 4. Whole-mount in situ hybridization analysis of Xenopus protein tyrosine phosphatase a (XPTPa) mRNA expression in early Xenopus development. A: Vegetal view of mid-gastrula stage embryos hybridized with digoxigenin-labeled sense (left) or anti-sense (right) XPTPa RNA probes. The arrowhead indicates the future dorsal aspect of the embryo. B: Lateral view of a stage 18/19 embryo. The anterior is to the left. C: Lateral view of a stage 22 embryo. Highest levels of XPTPa transcript expression appear in the forebrain (fb) indicated by the arrowhead. D: Dorsal view of a stage 24 embryo. Intense staining is evident in the forebrain (fb) and expression is now also seen in the visceral arches (va). E: Lateral view of a stage 27/28 embryo. F: Lateral view of a stage 31/32 embryo. Prominent staining can be seen in the forebrain (fb), epiphysis (ep), hindbrain (hb), and visceral arches (va). Some staining is also apparent in the otic vesicle.
