Analysis of transcription factors expressed at the anterior mouse limb bud.

ABSTRACT: Limb bud patterning, outgrowth, and differentiation are precisely regulated in a spatio-temporal manner through integrated networks of transcription factors, signaling molecules, and downstream genes. However, the exact mechanisms that orchestrate morphogenesis of the limb remain to be elucidated. Previously, we have established EMBRYS, a whole-mount in situ hybridization database of transcription factors. Based on the findings from EMBRYS, we focused our expression pattern analysis on a selection of transcription factor genes that exhibit spatially localized and temporally dynamic expression patterns with respect to the anterior-posterior axis in the E9.5-E11.5 limb bud. Among these genes, Irx3 showed a posteriorly expanded expression domain in Shh-/- limb buds and an anteriorly reduced e
