Fig. 8. Developmental expression of RFX4_v3. (A-E) Whole-mount embryos at the
indicated embryonic days (E) in which the RFX4_v3 transcript is indicated by
the blue digoxigenin staining. (C) Whole-mount suggests minimal staining
rostral of the zona limitans (zl); however, a section through the plane
indicated as C' shows staining of the dorsal cortex (cx). (D,E)
Wholemounts at E10.5; (F) midline sagittal section; (G-I) coronal sections
through similar embryos. The arrowheads in F-H indicate the lost expression in
the telencephalic dorsal midline at E10.5. (J-M) One sagittal (J) and three
rostral-to-caudal coronal sections through the head at E12.5. Note the lack of
staining in the telencephalic dorsal midline (arrowheads in J,K) in the
epiphysis (ep) in L and in the fourth ventricle choroid plexus (ch) in M.
