摘要: Runx2是转录因子Runxx家族成员之一,作为骨细胞的特异转录因子,对骨组织的形成和重建起着重要作用。Runxx调控间充质干细胞向成骨细胞分化,促进软骨细胞的成熟和软骨的血管化,与破骨细胞分化及细胞外基质的形成密切相关,与骨髓内皮细胞的迁移和浸润、血管增生和肿瘤细胞的浸润、牙齿和皮肤毛囊发育也密切相关。通过对Runx2基因调控机制的研究,已为骨折的愈合及骨代谢性疾病的预防和治疗提供了新的思路。

Abstract:

Runx2 is a member of the Runt homology domain family of transcription factors. As a specific transcription factor for osteocytes, Runx2 plays an important role in the formation and reconstruction of bone tissue. It can determine the differentiation of multipotent stem cells into osteoblastes, promote the matu
rity of chondrocytes and vascularization of cartilage. Runx2 is also associated with the formation of osteoclasts and intracellular matrix, the marrow endothelial cell migration and infiltration, the blood vessel proliferation and the tumor
cell infiltration, and the tooth and skin hairfollicle growth process is also closely connected. Progress in the research of the molecular mechanism regulated by Runx2, a master regulatory gene for activating the osteoblastes genesis, has provided novel insights for the therapeutic strategies of the metabolic diseases of bone.

Key words: Runx2; osteoblast; chondrocyte; osteoclast; regulation
