Fig. 1. The expression pattern of Hand1 and Xsal-1 in the early Xenopus embryo. The white numbers indicate the developmental stage of the embryo. Expression of Hand1 (A) is first detectable immediately following gastrulation and continues into the swimming tadpole stage in the middle LPM. At stage 20, it is clear that the Hand1 staining does not extend to the posterior end of the LPM. Xsal-1 (B) is expressed during late gastrulation in the presumptive neural plate, and by stage 14 in the posterior LPM (arrows). Expression in the posterior LPM disappears by the end of neurulation, while expression in the neural tube persists into the late tailbud stage. The embryos are viewed from the side with dorsal up and the anterior end to the left, with the exception of the stage 12 Xsal-1 staining where the embryo is viewed from the posterior end looking at the dorsal surface.
