abstractText | Here, we show that Shh-Cre-mediated deletion of Wntless, the Wnt cargo protein, in mouse posterior limb mesenchyme causes bone syndactyly of the 3rd and 4th digits, resembling the human Malik-Percin type. The Shh descendants gradiently distributed from digit 5 to posterior half of digit 3 in wild-type limbs, however, they abnormally increased in posterior digit 3 in Wntless(Shh-Cre) . Wntless(Shh-Cre) limbs displayed altered expression of hedgehog pathway genes and impaired noncanonical Wnt signaling activity. We further showed that the anterior limb mesenchymal cells in the Wls(Shh-Cre) served as a source of Wnt5a to reorientate the adjacent Wls-lacking Shh lineage cells to move anteriorly and subsequently led to syndactyly, suggesting that aberrant mesenchymal cell movement/condensation may underlie the pathogenesis of syndactyly. |
