摘要: 配对相关同源基因1(paired related homeobox 1, Prx1/Prrx1/MHox)在胚胎肢芽和颅面发育中高表达,成体中的Prx1+细胞分布在长骨的骨膜、骨髓和颅骨的骨缝中,表现出间充质干细胞(mesenchymal stem cells,MSCs)或骨骼干细胞(skeletal stem cells,SSCs)的特征。近期的研究显示,表达Prx1基因的骨骼干细胞(Prx1+ skeletal stem cells, Prx1+SSCs)参与了骨骼的创伤愈合和对机械应力的应答反应。同时,牙周膜中Prx1+细胞在牙周组织正常发育和缺损修复中发挥的作用也受到关注。该文回顾Prx1基因和Prx1+细胞的特征和功能,总结Prx1+SSCs对骨骼改建或修复的作用,有助于SSCs在调控颅面骨生长、促进牙槽骨再生中的深入研究。

Abstract: The paired related homeobox gene Prx1 is highly expressed during embryonic lib formation and craniofacial development. Postnatal Prx1+cells located in periosteum, bone marrow or calvarial sutures display the characteristics of mesenchymal stem cells(MSCs) or skeletal stem cells(SSCs). Recent research has shown that Prx1+SSCs participate in fracture healing and respond to mechanical forces in bone. At the same time, Prx1+cells in the periodontal ligament are noticed for its contribution to the normal development and defect repair of periodontal tissues. This paper reviews the characteristics and function of Prx1 gene and Prx1+cells and gives a summary of the role Prx1+SSCs play in bone remodeling and repair, which is helpful for the further studies of SSCs in regulating orchestrate craniofacial growth and promoting the regeneration of alveolar bones.

Key words: skeletal stem cells, Prx1, craniofacial, bone remodeling, mechanical force
