Table 1. Wnt8a expression in r4 at 5-8 somites depends on Fgf expression.
5-8-somite mouse embryos of the indicated genotypes were hybridized with the Wnt8a probe and subjectively scored for the intensity of r4 labeling as normal, reduced, or absent. The number of embryos in each category is indicated.
