  sub:_4 prov:value "We found that Gbx2 expression was normal in Lmx1b-/- embryos before the 4-somite stage (Fig. 5B). However, unlike the wild-type embryo, in which the Gbx2 transcript was found at the rostral end of the hindbrain (arrow in Fig. 5C), Gbx2 expression was barely detectable in Lmx1b-/- embryos at the 4-somite stage (Fig. 5D). By contrast, the same level of Gbx2 expression was detected in the caudal hindbrain of both wild-type and Lmx1b-/- embryos (arrowheads in Fig. 5C,D), suggesting specific Lmx1b-dependent expression of Gbx2 in the rostral hindbrain.
