In situ expression of GJA1 in the human embryo.

(H) Rostral trunk-level HE section of same embryo as in (A–D).

(I) GJA1 is highly expressed in the dorsal neural tube, the dorsal roots and ganglia, the dermatome and the splanchnopleural mesoderm, with basal expression in all other tissues of the section as compared with
