Fig. 1. sfrp1 expression in cardiac precursors and differentiating myocardium. (A-H,J,K) Whole-mount RNA in situ hybridisation (WISH) analysis of sfrp1 on Xenopus embryos at the indicated stages. (I,L) WISH analysis on sections of stage 24 (I) and stage 32 (L) embryos, showing sfrp1 expression in cardiac progenitors (arrowheads in I) and in the differentiated myocardium (L). (M,N) WISH analysis on stage 18 embryos showing nkx2-5 (M) and gata6b (N) expression in the common cardiac progenitor population (arrowheads), confirming sfrp1 expression in this region (arrowhead in E).
