Genes expressed in hypothalamus, adenohypophysis, and in neurohypophysis. (A–D) uo:ion003 is expressed in telencephalon, diencephalon, and mesencephalon between 24 and 72 h. (D) The section shows that hypothalamic cells and cells in the posterior pars distalis (APD and PI are demarcated by pomc, red) express uo:ion003. (E–H) crabp1a is expressed in the presumptive neurohypophysis. crabp1a is expressed close to the adenohypophysis from 24 to 72 h (E–H) and in the telencephalon and tectum at the later stages. Sagittal sections through the pituitary (pomc, red) show crabp1a expression dorsal to the adenohypophysis in neurohypophysial cells (L). Side views, anterior to the left. (A and E) 24 h; (B and F) 48 h; (C and G) 72 h; scale bar is 100 μm. (D and H) 15 μm sagittal sections, anterior to the left, dorsal up, through the pituitary and adjacent hypothalamus at 72 h; scale bar: 50 μm.
