Fig. 6. wnt8b overexpression promotes expression of posterior hypothalamic
markers. Lateral (A-F) views of brains of wild-type embryos (A,D) and embryos
in which cells overexpressing wnt8b (B,C,E,F) have incorporated into
the hypothalamus. C and F show the same embryos as B and E after
immunocytochemistry to reveal the positions of cells expressing
wnt8b. The arrows in B,C point to decreased rx3 expression
(B,C) compared to control (A). Abbreviations: pv, posterior-ventral
hypothalamus; t, telencephalon.
