Figure 7. Xenopus tropicalis Hex and Cerberus. In situ hybridization analysis of tropicalis embryos with tHex (A-D) and tCerberus (E-G) antisense probes. The top row shows vegetal views (dorsal up), and the second row shows lateral views (dorsal left) of tHex (A,B) and tCerberus (E,F) expression in the anterior endoderm of the early gastrula. Note tCerberus is more broadly expressed than tHex. C,G: Midsagittal sections (dorsal left) of gastrula embryos, hybridized in whole-mount with tHex and tCerberus probes. D: A cleared tail bud embryo (anterior right) shows tHex transcripts localized to the presumptive liver region. st., embryonic stage. |
