No changes in GABAergic survival or proliferation due to PS. At E13, NS and PS offspring showed no significant differences in survival of GAD67GFP+ cells born at E12 in the ventral (A) or dorsal (B) telencephalon. NS (C,E,G,I) and PS (D,F,H,J) offspring showed no difference in apoptotic cells at E13 (C,D) or E14 (E,F) but an increase in apoptosis at E15 (G,H) that was specific to non-GABAergic cells (I,J). Proliferative markers in the ganglionic eminence of NS and PS offspring were similar at E13 (K) and showed a trend difference at E14 (L) that was greater in caudal regions (H) (* indicates p<0.05 by two-tailed student’s t-test; arrows indicate caspase-3+ cells that show no labeling with GAD67GFP). Scale bar=200 µm.
