(A-L) Two vegetal cells of eight-cell stage embryos were injected with either XEBF2 MO and XEBF3 MO together, or control MO. β-gal mRNA was coinjected as a marker of the injected side. The expression level of target genes was examined at stage 20/21. In all panels the right side is the injected side, showing the blue color of X-gal staining. The (purple) expression levels of myod (B and C), m-cadherin (E and F), seb-4 (H and I), and myf5 (K and L) are downregulated by XEBF2 MO and XEBF3 MO together or by NLS-DN-EBF (brackets), while control MO does not change their expression levels (A, D, G, and J). (M, N) Two vegetal cells of eight-cell stage embryos were coinjected with XEBF2 MO, XEBF3 MO and hGR-XEBF2 mRNA, followed by DEX treatment from the late gastrula stage (stage 11/11.5) to the early tailbud stage (stage 20). The expression of m-cadherin is downregulated without EBF activity (M), but expression was rescued in the presence of EBF activity (N). All panels show dorsal views.
