FGF overexpression supresses cerebellar cell fates. (A-C) Electroporation of Fgf8b + gfp at E3 (arrow) disrupts Lhx9 at E6, producing both ectopic expression (arrowheads) and gaps (arrows). (D,E) Electroporation of gfp (D) or Fgf8b + gfp (E) at E4 produces markedly different numbers of GFP-labelled cells. (F) Electroporation of Fgf8b + gfp at E3 cell-non-autonomously induces at E5 ectopic proliferation (PH3 in red). (G) Electroporation of Atoh1-cre + stop-gfp into rl at E3 (arrow) labels rhombic lip derivatives at E7. (H,I) Co-electroporated Fgf8b increases the proportion of ventral derivatives (H) and downregulates the deep cerebellar nucleus marker Tbr1 (I). Scale bars: 200 μm (D,E,G,H); 100 μm (F, left and middle); 50 μm (F, right). rl, rhombic lip.
