Fig. 3. Anatomical and time-course analysis of GABA and x-Lhx7 expression
in developing Xenopus forebrain. The developmental time-course of GABAergic
(GABA, red IF) neurons is followed in the telencephalon of stage 32 (A),
stage 37 (B), and stage 42 (C) embryos, and compared to the expression of x-
Lhx7 (purple, ISH) on transverse sections at the same antero-posterior level in
embryonic Xenopus forebrain. Note that GABA and x-Lhx7 are never
colocalized. Arrows in panel C point to presumptive tangentially migrating
cells. Scale bar, 100 Am. Ba, branchial arches; lge, mge, lateral and medial
ganglionic eminences; pa, pallium; aep/poa, anterior entopeduncular and
preoptic areas. |
