Expression of sphk2 during embryogenesis was examined by whole-mount in situ hybridization.
A–J, pictures present lateral views (A–F and H–J) and dorsal views (G): from the bud to the 20-somite stages presented anterior to the left (D–F, H, and I). J, magnified image of a dome stage embryo. sphk2 transcripts were detected in the blastoderm and the YSL, as indicated by the arrows. Scale bar, 200 μm.
