Fig. 4. Sox8 regulates the onset of expression of Slug and Sox9. (A)
Embryos injected in one blastomere at the two-cell stage with 30 ng of Sox8mo
exhibited reduced Sox9 and Slug expression at stage 12.5 and stage 14. Lateral
view in all panels, anterior is towards the right (control side) or to the
left (injected side). (B) Quantification of the in situ hybridization
results. The numbers in parentheses indicate the number of embryos
analyzed.
