FIG. 1.

Oliogdendroglial expression of Sox4 and Sox11. Antibodies directed against Sox4 (G, H, and I) and Sox11 (J, K, and L) (both in green) were combined with antibodies directed against Sox10 (A and D), Olig2 (B and E) and MBP (C and F) (all in red) in coimmunohistochemistry (M, N, O, P, Q, and R) on transverse sections of wild-type spinal cords from 18.5-dpc embryos. Images were taken from the marginal zone. Coexpression of Sox4 or Sox11 and oligodendroglial markers is visible as a yellow signal in panels M, N, O, P, Q, and R. Nuclei were additionally visualized by DAPI (4′,6′-diamidino-2-phenylindole) staining and are shown in blue in some panels (O and R).
