Figure 5. Displays the pattern of expression of B1-type Sox-type transcription factors in the early Xenopus embryo. Top: RT-PCR analysis at various embryonic stage; Center: in situ analysis at blastula stages; Bottom: in situ hybridization at early neurual stages (stage 13 and 15) for Sox1 (A and B), Sox2 (C and D) and Sox3 (E and F). Red arrow points to region of reduced Sox expression within the nascent neural plate (Grammer T, Zhang C, Klymkowsky MW, previously unpublished observations).
