Fig. 4 Nkx2.5 expression in ntl mutant embryos. Nkx2.5 expression is shown in wild-type (wt) embryos at the 17-, 18-, and 21-somite stages. pax-b expression at the midbrain–hindbrain junction anteriorly and the otic vesicle posteriorly serves as a marker of anterior–posterior distance for comparison. Marked posterior extension of Nkx2.5 gene expression is evident in ntl embryos at the 21-somite stage (lower-right panel) when compared to normal embryos (lower-left panel).
