Figure 2. Expression of pituitary specific genes in wild type and Rx-deficient embryos.
(A) Lhx3 expression in Rathke's pouch of an E9.5 wild type embryo. (B) Lhx3 expression in Rathke's pouch of an E9.5 Rx-deficient embryo. (C) Lhx3 expression in the anterior pituitary of an E10.5 wild type embryo. (D) Lhx3 expression in the dysmorphic anterior pituitary of an E10.5 Rx-deficient embryo. (E) Expression of Fgf10 in the ventral hypothalamus of an E9.5 wild type embryo. (F) Expression of Fgf10 in the ventral hypothalamus of an E9.5 Rx-deficient embryo. (G) Expression of Fgf10 in the posterior pituitary of an E10.5 wild type embryo. (H) Fgf10 expression in an Rx-deficient embryo. (I) Optx2 expression in the head of an E9.5 wild type embryo. (J) Optx2 expression in the head of an E9.5 Rx−/− embryo. (K) Optx2 expression in the neuroectoderm and head surface ectoderm of an E8.5 wild type embryo. (L) Optx2 expression in the head surface ectoderm of an E8.5 Rx−/− embryo. (M) Optx2 expression in the ventral hypothalamus and optic vesicle of an E10.5 wild type embryo. (N) Lack of Optx2 expression in an E10.5 Rx−/− embryo. a – anterior pituitary, p – posterior pituitary, OV – optic vesicle, RP- Rathke's pouch, VH – ventral hypothalamus.
