Figure Lengend Snippet: (A) Diagram of experimental schematic. E8.5 timed pregnant mice received 1.5 mg of 4-OHT through oral gavage and were sacrificed at E10.5. (B) Anatomical structure of sagittal section. lv, lateral ventricle; di, diencephalon; 3v, third ventricle; PTh, prethalamus; CPa, caudal paraventricular nucleus area; Tu, tuberal region; Ahy, anterior hypothalamus. (C) Coronal sections corresponding to the line in (B). (D and E) Sagittal sections of Rax-CreER T2 ;Ai9 mice. vfb, ventral forebrain; mv, mesencephalic vesicle; 4v, fourth ventricle. (F and G) High power images of (C) and (E) respectively. (H) Coronal view of retina. OC, optic cup; LP, lens pit. Tdtomato signal was boosted with anti-DsRed immunolabeling. Red fluorescence exhibited mosaic pattern limited to ventral regions of the telencephalon and diencephalon (C–G), and as robust expression was detected in neuroretina (H). Sections were counterstained with DAPI (blue). Scale bars: 100 µm (C, F–H), 200 µm (D, E).
