X-Delta-2, prospective somitic boundaries
X-Delta-2, nucleic acid
X-Delta-2 encodes the second Xenopus homolog of Drosophila Delta. It is expressed within the presomitic mesoderm in a set of stripes that corresponds to prospective somitic boundaries. Cloned by Wui-Chuong Jen et al. in Chris Kintner's laboratory.
Expression of X-Delta-2 at neural plate stage (A; dorsal view, stage 14), neurulae stage (B; dorsal view, stage 18), and tailbud stage (C; side view, stage 28). Note that X-Delta-2 is expressed within the paraxial mesoderm within stripes of cells that are located progressively more posterior as development progresses (arrows). Note also that X-Delta-2 expression occurs in a large domain in the tailbud.
