Comparison of Fgf8 and Fgf17 fate maps. Comparison of Fgf8 and Fgf17 fate maps in which progenitors were labeled at neural plate, early neurula, and late neurula stages. Xgal-stained coronal sections through E18.5 forebrains of Fgf8 ^CreER/+ and Fgf17 ^CreER/+ embryos on the (A-X) ROSA26R and (A′-X′) TauR backgrounds. Tm was administered at (A-H, A′-H′) E7.5, (I-P, I′-P′) E8.5, or (Q-X, Q′-X′) E9.5, marking cells from E8-E9.5, E9-E10.5, and E10-E11.5, respectively (see Experimental procedures). Abbreviations: m, mitral cell layer; VZ/SVZ, ventricular/subventricular zone; AOA, anterior olfactory area; TT, taenia tecta; Cx, cortex; IG, indusium griseum; S, septum; Str, striatum; NAc, nucleus accumbens; DB, diagonal band of Broca; MnP, median preoptic area; SFi, septofimbrial nucleus (septum); TS, triangular septal nucleus; BST, bed nucleus of the stria terminalis; GP, globus pallidus; VP, ventral pallidum. PFC/Cortex areas: Cg, cingulate; I, insular ; IL, infralimbic; M, motor; O, orbital; PrL, prelimbic; So, somatosensory.
