Expression of a CG7878-related gene. (A) Ddx43 is diffusely expressed throughout the neural plate, PPE and dorsal epidermis [Anterior view]. (B) At neural tube closure, it is very weakly expressed in the neural tube, a few placodes (dlp, L) and migrating neural crest [Side view]. (C) At larval stages it is expressed throughout the brain, retina, several placode derivatives (olf, oto, L), branchial arches, somites, heart and nephric mesoderm [Side view]. Transverse sections at midbrain (D), hindbrain (E) and spinal (F) levels demonstrate neural (mb, r, hb, sc), lens, branchial arch, heart, otocyst, somite and nephric mesoderm expression.
