Fig. 6. Caudal displacement and expansion of Hox protein expression domains in
Gdf11-/- mouse embryos. (A-J) Hoxc6-Hoxc10
expression in cross-sectioned E12.5 ventral spinal cords isolated from
Gdf11+/+ (A,C,E,G,I) and Gdf11-/-
(B,D,F,H,J) mouse embryos. Motoneurons and dorsal root ganglia are marked by
Isl1 or Isl1/2 expression. (K) A diagram depicts the Hox expression
domains in Gdf+/+and Gdf-/- spinal
cords. Broken lines indicate the RC levels in A-J. Position of the limbs is
represented in gray. Scale bar: 100 µm.
