Immunocytochemical localization of a novel pituitary polypeptide "7B2" in the gastro-intestinal tract of the rat.

abstract：:The pituitary gland is first evident in rainbow trout two weeks before hatching. Differentiation of prolactin and ACTH cells is not marked until 3-4 days after hatching when the follicular arrangement of the prolactin cells become apparent. There is no difference in the time of development of either prolactin or ACTH ...
