Role of N‐cadherin in bone formation
Abstract
Cell–cell adhesion mediated by cadherins is essential for the function of bone forming cells during osteogenesis. Here, the evidence that N‐cadherin is an important regulator of osteoblast differentiation and osteogenesis is reviewed. Osteoblasts express a limited number of cadherins, including the classic N‐cadherin. The expression profile of N‐cadherin in osteoblasts during bone formation in vivo and in vitro suggests a role of this molecule in osteogenesis. Functional studies using neutralizing antibodies or antisense oligonucleotides indicate that N‐cadherin is involved in the control the expression of osteoblast marker gene expression and differentiation. Cleavage of N‐cadherin during osteoblast apoptosis also suggests a role of N‐cadherin‐mediated‐cell–cell adhesion in osteoblast survival. Hormonal and local factors that regulate osteoblast function also regulate N‐cadherin expression and subsequent cell–cell adhesion associated with osteoblast differentiation or survival. Signaling mechanisms involved in N‐cadherin‐mediated cell–cell adhesion and osteoblast gene expression have also been identified. Alterations of N‐cadherin expression are associated with abnormal osteoblast differentiation and osteogenesis in pathological conditions. These findings indicate that N‐cadherin plays a role in normal and pathological bone formation and provide some insight into the process involved in N‐cadherin‐mediated cell–cell adhesion and differentiation in osteoblasts.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
