Fig. 7. The GATA-4 gene is activated in the endocardium of the developing heart. Shown is a sagittal section of a stained stage 38 embryo which has undergone the whole-mount in situ hybridization procedure. Ventral is towards the bottom and anterior is to the left. Note that only the inner layer (endocardium) of the developing heart is stained. In this sample, the endocardial cells have separated from the overlying primitive myocardium in the region consisting of cardiac jelly (arrow). Image published in: Kelley C et al.
