motionless embryos have reduced numbers of hypothalamic DA neurons and exhibit localized patterns of apoptosis. Lateral views (except C and D) of wildtype (left) and mot (right) embryos labeled with (A–F) anti-TH antibody, (G and H) anti-acetylated tubulin, or (I–L) TUNNEL stain. (A and B) 30-h embryos showing reduced hypothalamic DA neurons. (C and D) Ventral view showing a mild cyclopic brain, reduced hypothalamic DA neurons, and normal aac in 2-day-old mot embryos. (E and F) 2-day-old embryos showing few poorly differentiated hypothalamic THir cells and absent LC. (G and H) 30-h embryos showing that the major axonal tracts are grossly intact and the absence of brain ventricles. (I and J) 33-h mot embryos do not display excessive cell death compared to wildtype siblings. (K and L) 52-h embryos showing restricted cell death in the telencephalon and lens of the mot embryos. Abbreviations: aac, arch-associated CA cells; AC, anterior commisure; cb, cerebellum; Hy DA,hypothalamic dopaminergic neurons; LC, locus coeruleus; PC, posterior commisure; POC, postoptic commisure; t, telencephalon; te, tectum; tg, tegmentum; v, ventricle. Scale bar: 55 μm (A, B, I–L) and 110 μm (C, D, E, F, G, H). |
