Fig. 3. Osgep expression during Xenopus development. Spatio-temporal expression pattern of osgep visualized by whole mount in situ hybridization (WMISH). Embryonic stages and scale bars are indicated in each panel. Upper part: WMISH with exterior view. Scale bars are equivalent to 500 μm. Black dashed lines represent section planes. Lower part: WMISH following sections. Scale bars are equivalent to 100 μm. (A) Animal view, (B) lateral view and (C) vegetal view of Xenopus embryos in very early stages showed an osgep expression in the animal pole (arrowhead) and in the developing neural plate (arrow) beside the blastopore (bp). During Xenopus embryogenesis osgep is strongly expressed in neural tissue which is revealed by dorsal view (D, G) in the dorsal neural tissue and neural tube (nt) and by anterior view (E, F) in the anterior neural plate (anp), neural tube (nt) and the developing eye, more precisely in the eye vesicle (ev). (H, I, J, K) Lateral view, osgep expression is detected in the somites (s), the eye vesicle (ev) or eye (e), the embryonic kidney (pronephric anlage (pa), pronephros (p)), the otic vesicle (ov), the brain (b) and the mandibular (ma), hyoid (ha) and branchial arch (ba) which will develop into the cranial cartilage. (L) Parasagittal view showed an expression of osgep in the neuroectoderm (ne). The transversal view (M, P) revealed osgep transcripts in the mesencephalon (m), neural crest cells (ncc), eye vesicle (ev). Horizontal sections (N, O, Q, R) showed an expression in the somites (s), spinal cord (sc), the mandibular (ma), hyoid (ha) and branchial arches (ba), embryonic kidney (pronephric tubule (pt)) as well as in the eye, more detailed in the lens (le) and ciliary marginal zone (cmz).
