Fig. 5. Expression of Pax-5 during Xenopus embryogenesis and of
Pax-2 in the thyroid anlage. Transcripts for Pax-5 (A–E) and Pax-2
(F,G) were detected by whole-mount in situ hybridization. Sections of
embryos stained in whole mount were cut at 50μm. A-C: Pax-5
expression can be detected at the MHB (arrowhead) and faintly in the
otic vesicle (arrow). Lateral views of stage 24 (A), 30 (B), and 38 (C)
embryos are shown. Horizontal lines (A) indicate the levels of the
sections in D and E. D,E: Horizontal sections through a stage 24
embryo to illustrate Pax-5 expression at the MHB (D) and in the otic
vesicle (E). F,G: Pax-2 expression in the head region of a stage 34
embryo. Arrowheads indicate the stained thyroid anlage. Lateral
(A-C, F) and ventral (G) views with anterior to the left are shown. |
