Fig. 6. Lhx6 expression is enlarged in cavefish, especially in columns
of cells extending from the SP. (A-H) Comparison of Lhx6
pattern between surface fish (left) and cavefish embryos (right) at indicated
stages on lateral (A,B) and ventral (C-F) in toto views. G and H show frontal
sections through the forebrain of 72 hpf embryos, where arrows point to
anteroventral located Lhx6 cells. In A and B, an inset shows a
transverse section at SP level (orientation given in A). Scale bar: 50
µm.
