Fig. 1. Expression of XGrhl1 is restricted to the ectodermal layer. (A)
RT-PCR analysis of XGrhl1 expression in staged embryos during
development (n=5). Ornithine decarboxylase (ODC) gene expression was
used as a control for RNA concentration. -RT, no reverse transcriptase; -, no
RNA. (B) XGrhl1 expression is restricted to the superficial epidermal
layer of the developing embryo. RT-PCR analysis of XGrhl1 and
developmental gene expression in different ectodermal tissues at stage 11 of
Xenopus development.
