通过细胞粘附分子,特别是钙粘蛋白,直接细胞与细胞的相互作用,是至关重要的形态发生,组织结构,细胞分选和分化。从小鼠遗传学和体外研究中发现,N-钙粘蛋白(钙粘蛋白-2)和钙粘蛋白-11在骨骼系统中的作用部分重叠,但又不同。这两种钙粘蛋白对于成骨谱系的前体定型都很重要,Cdh 2和Cdh 11的基因消融导致骨骼生长缺陷和骨形成受损。虽然Cdh 11定义了成骨谱系,但体内成骨细胞中Cdh 2的持续存在实际上抑制了它们的终末分化并损害骨形成。钙粘蛋白的作用涉及细胞-细胞粘附和干扰细胞内信号传导,特别是Wnt/β-连环蛋白途径。钙粘蛋白-2和钙粘蛋白-11都与β-连环蛋白结合,从而调节其细胞质库和转录活性。最近的数据表明,钙粘蛋白-2也干扰Lrp 5/6信号通过螯合这些受体在非活性池通过轴结合。这些数据扩展了钙粘蛋白在骨形成细胞中的生物学作用,并为开发旨在增强骨形成的治疗策略提供了新的机制。
Direct cell-to-cell interactions via cell adhesion molecules, in particular cadherins, are critical for morphogenesis, tissue architecture, and cell sorting and differentiation. Partially overlapping, yet distinct roles of N-cadherin (cadherin-2) and cadherin-11 in the skeletal system have emerged from mouse genetics and in vitro studies. Both cadherins are important for precursor commitment to the osteogenic lineage, and genetic ablation of Cdh2 and Cdh11 results in skeletal growth defects and impaired bone formation. While Cdh11 defines the osteogenic lineage, persistence of Cdh2 in osteoblasts in vivo actually inhibits their terminal differentiation and impairs bone formation. The action of cadherins involves both cell-cell adhesion and interference with intracellular signaling, and in particular the Wnt/β-catenin pathway. Both cadherin-2 and cadherin-11 bind to β-catenin, thus modulating its cytoplasmic pools and transcriptional activity. Recent data demonstrate that cadherin-2 also interferes with Lrp5/6 signaling by sequestering these receptors in inactive pools via axin binding. These data extend the biologic action of cadherins in bone forming cells, and provide novel mechanisms for development of therapeutic strategies aimed at enhancing bone formation.
