牙龈干细胞生物学潜能的研究进展
A review on recent developments in pluripotency of gingiva-derived mesenchymal stem cells

摘要： 间充质干细胞（MSC）可从多种人体组织中分离获得,具有自我更新和多向分化的潜能。目前已证实,牙龈组织中也存在MSC,即牙龈干细胞（GMSC）。GMSC易于分离获得,表型稳定,增殖速度快,体外长期培养时还能维持正常的核型和端粒酶活性,日益成为组织工程和再生医学研究的干细胞来源。本文就其分离鉴定、生物学特性、分化能力等方面的研究进展作一综述。
Abstract: Mesenchymal stem cells (MSCs) which can be isolated from multiple tissue, have two specific characteristics: self-renewal and multi- or pluripotency. Recent evidence has shown that MSCs also located in gingiva, then be named as gingiva-derived mesenchymal stem cells (GMSCs). GMSCs represent a unique population of MSCs that can be easily isolated and obtained. In addition to maintaining a normal karyotype and telomerase activity in long-term cultures, GMSCs can display a stable phenotype and rapidly proliferate in vitro. Therefore, GMSCs are increasingly become the sources of stem cells for tissue engineering and regenerative medicine research. This review described the research progress of GMSCs’ separation and identification, biological characteristics and differentiation ability and so on.
