Multiple points of interaction between retinoic acid and FGF signaling during embryonic axis formation
... We hypothesized that as both FGF (Isaacs et al., 1998; Pownall et al., 1996) and retinoid signaling (Blumberg et al., 1997) are required for the expression of posterior markers, these pathways might converge on one or ...
