Fig. 2. The neural plate is multi-layered. Cross sections through the anterior lateral neural plate at the tailbud-1 som stage; dorsal is towards the top. (A) TEM micrograph, in which superficial cells are pseudocolored in blue, deep cells in red and the EVL in green. (B) Embryo double labeled with -ß-cat (red) and -Sox3C (green). (C) Embryo double labeled with -ß-cat (red) and -PH3 (green). Abbreviations are as in Fig. 1. Scale bars: in A, 5 µm; in B, 20 µm for B,C.
