Fig. 7. Limb ablation does not alter Lmo4 expression. Limb ablations were performed unilaterally at stage 15 and analyzed at stage 28. Lmo4 expression appeared unchanged in DRG (A) and in the spinal cord at LS2 (D) after limb ablation. By contrast, Pea3 expression was lost after limb ablation (B,E). (C,F) Sections adjacent to the dualstained A,B,D,E sections were stained for Isl1/Isl2 expression to estimate numbers of surviving neurons. Scale bar: 85 µm.
