Figure 4. Early cardiac markers express normally in the Nkx2.5 and Nkx2.7 double knockdown morphants (Nkx2.5/2.7-MO).
Whole mount in situ hybridization showed that the expression patterns of hand2 and tbx5, lateral plate mesoderm markers, were similar between wild-type (WT) and Nkx2.5/2.7-MO embryos at 10 hpf (A vs. B; C vs. D, respectively). Arrows: heart field.
