DLK1 Protein Expression during Mouse Development Provides New Insights into Its Function

Figure 4

DLK1 protein expression in the developing pituitary gland. ((a)–(e)) They show sections of ED10, -13, -15, -16, and -18 pituitary glands, respectively, with ED10, prominent DLK1 staining in Rathke’s pouch (arrow), and the developing hypothalamic region (arrowhead). From ED13 onwards, DLK1 protein expression becomes confined to the developing pituitary gland and reaches the strongest intensity at ED16. On ED18, the pituitary gland is among the few organs which still express DLK1 protein. Scale bar in (a) is applicable for ((b)–(e)).
