Fig. 2 (right). RAR gamma isoforms are differentially expressed. Specific probes were hybridized to late neurula/early tailbud embryos. (A) Diagram
indicating position and size of isoform-specific probes, which were derived from clones isolated by Blumberg et al. (1992). (B) RARgammaI expression
is seen solely in the anterior expression domain. (C) RARgamma2 is expressed both in the head endomesoderm and in the posterior prospective
tailbud area. (D) A control sense probe shows no staining after an equal time of incubation. Artifactual precipitates of proteinaceous material
can be seen in the gut cavity (see D), Bar, 200 umm. |
