Model of Tbx2 function in the posterior hindlimb mesenchyme
During normal limb bud outgrowth (E10.5) the expression domains of Shh (red), Grem1 (yellow) and Fgf4/9/17 (green) are in close proximity allowing propagation of the e-m signaling loop. Following proliferative expansion of ZPA-derived cells, a broadened Tbx2 expression (blue) causes Grem1 repression. Progressive displacement of Grem1-secreting cells from the AER terminates e-m signaling (E11.5, dotted arrows). The diagrams illustrate these dynamic signaling activities. Failure of Grem1 repression in Tbx2-deficient hindlimbs causes prolonged e-m signaling.
