Expression of DA pathway genes in Etv5 knock-out embryos. Coronal sections of E16.5 embryos were examined for the expression of DA pathway genes. Immunofluorescence for TH (A, B), DAT (C, D), and VMAT2 (E, F) were similar in Etv5−/− (KO) embryos and control (WT) mice. The expression pattern of the regulator of DA differentiation Nurr1 was also indistinguishable in Etv5−/− embryos and controls (G, H). Scale bar, 80 μm.
