Figure 8. Expression of a CKIIβ-related gene. A: CKIIβ is expressed throughout the ectoderm of the gastrula (dorsal view). B: At neural plate stages, epidermal staining continues, but expression is enhanced in the neural plate and preplacodal ectoderm (PPE; anterolateral view). C: At neural tube closure, CKIIβ is expressed throughout the neural tube, in placodes (AH, olf, L) and neural crest (anterior view). D: At tail bud stages, brain, retina, placodal structures (olf, L, crg, oto), and branchial arches are stained (side view). E: At larval stages, the nephric mesoderm is additionally stained (side view). Transverse sections at hindbrain (F) and spinal (G) levels demonstrate neural (hb, sc), branchial arch, otocyst, cranial ganglion (IXg), somite, and nephric mesoderm expression. |
