The pituitary anlage moves into the head via a common invagination of the hypophyseal-stomodeal placode. (A–G, I, J) pomc expression. (H) gh expression. Embryos in (B) and (G) are counterstained for nk2.1 in red. Ages of embryos are indicated in bottom-right corner (hpf, hours after fertilization). (A–G) Lateral views. (H) Transverse section through pituitary (compare with histological sections of larvae at 72 and 120 hpf at http://zfin.org/zf_info/anatomy/dev_atlas.html). (I, J) Frontal views (with magnification of pituitary region in insets). (D) Magnified pituitary region of embryo shown in (C). Putative hypothalamic pomc-positive cells in (A, C, E, G, J) are indicated by arrows. Note the progressive spreading of pomc-positive cells along the anteroposterior axis in (A–E), leading to two distinct pomc domains at the anterior and posterior ends of the pituitary anlage (F, G). Abbreviations: oc, oral cavity; fg, foregut; ca, cartilage. |
