Fig. 4. Whole-mount in situ hybridization analysis of XdrgmRNA distribution in Xenopus embryos. Embryos in A through E were hybridized with
an Xdrg antisense probe. No hybridization to a control sense probe was detected under similar conditions (data not shown). (A! Dorsal and(B! lateral views
of the stage 17 (neurula) embryos showing expression in neural folds (nf). IC) A stage 22 embryo showing expression in developing brain (br), otic vesicle
(ov) and the neural tube (ntJ. Note the strong signals In the anterior and posterior regions of the CNS. (D,E) A stage 32 embryo showing expression In
various head structures (brain. br: eye, ey; otic vesicle, ov), branchial arches-like structures (ba) and spinal cord. As a positive control, in (F), a stage 22
embryo was hybridized fa an antisense probe derrved from the Xenopus N-CAM cDNA (Kintner and Melton. 1987). under conditions similar to those used
for the Xdrg probe. |
