Figure Caption

Fig. 4 Tcf3 is required for proliferation but not for dorsal progenitor patterning. (A–D) Both tcf3a (A, B) and tcf3b (C, D) are expressed at higher levels in tcf7 morphants. (E) The mitotic index in dorsal, intermediate and ventral domains is significantly reduced in tcf3a/tcf3b double morphants. *p < 0.05 by T-test, error bars indicate ± SEM. (F, G) Expression of msxc and (H, I) pax3 is unaffected in tcf3a/tcf3b double morphants. (J, K) Expression of dbx2 is eliminated in tcf3a/tcf3b double morphants, but the intermediate progenitor domain is not shifted dorsally as indicated by iro3 expression (L, M). (A–D) 12 μm cross-sections are shown. (F–M) Lateral mounts are shown. Scale bars = 10 μm.
