We have shown that genetic ablation of Cdh2 (N−cadherin gene) in osteolineage cells results in osteopenia and decreased osteoprogenitor number. Paradoxically, others have shown that mice overexpressing Cdh2 in osteoblasts are also osteopenic; an action linked to a negative effect of N−cadherin (Ncad) on Wnt signaling, via sequestration of low density lipoprotein receptor−related protein−...
