Fig. 5. Expression of Psf3. All embryos are oriented anterior to the left and dorsal to the top, except those in (C and D) which are dorsal views oriented anterior to the top. (A) Stage 13 embryo. Arrowheads demarcate anterior and posterior regions of neural expression. (B) Stage 22 embryo. (C) Stage 32 embryo. The bracket demarcates the right half of the CNS, and the left margin of the bracket aligns with the inner boundary of the ventricular zone. (D) Stage 37 embryo. (E) Stage 26 embryo. (F) Stage 32 embryo. (G) Stage 37 embryo. (H) Section through a stage 37 embryo at the level of the hindbrain, with the dorsum oriented to the left. Note the consistent levels of expression in the dorsal CNS compared to Psf1 (Fig. 3H) and Psf2 (Fig. 4I). (I) Sense control stage 30 embryo. (J) Sense control stage 37 embryo. All labels follow that listed in the legend to Fig. 1. The scale bar in G equals 380 mm in (A), 550 mm in (B) and (E–G), (I–J), 200 mm in (C and D), and 125 mm in (H). |
