Xnrs and Activin Regulate Distinct Genes during Xenopus Development: Activin Regulates Cell Division
Figure 2
Expression patterns of genes regulated by activin and nodal-related proteins.
(A,B) Expression pattern of Chordin, a gene that is mis-regulated following inhibition of Xnr signalling. Note that Chordin transcripts are restricted to the dorsal marginal zone. (C–F) Expression pattern of DNMT1, a gene that is mis-regulated following inhibition of activin signalling. (C) and (D) show embryos hybridised using a sense probe; (E) and (F) show embryos hybridised using an antisense probe. Note that DNMT1 is expressed ubiquitously.
