Fig. 4. Expression patterns of ET3. A,C: ET3 is expressed in the rostral trunk region, where melanophores later migrate to the yolk at stages 25 (A) and 31 (B). B,D: ET3 is expressed in thecaudal trunk region where melanophores later localize in the NT. E,F: Dct expression represents
migrating melanoblasts. E and F are serial sections of C and D, respectively. In the rostral region, melanoblasts seek yolk migrating through the ventral pathway (E). In the caudal region, melanoblasts localize in the NT or migrate to the fin (F). Scale bar ¼ 100 mm. |
