文题释义:
牙髓干细胞:
来源于牙髓腔内的软组织,可自我更新,有着较强的克隆形成能力,与骨髓间充质干细胞有极其相似的免疫表型(CD105+/CD73+/CD34-/CD45-)。牙髓干细胞具有多向分化的潜能,在特定条件下能够分化为骨、软骨、神经样细胞、肌细胞等类型。
牙髓干细胞的转化医学研究意义:牙髓干细胞具有来源丰富、采集方便、免疫原性低、无伦理争议等优点,因此,牙髓干细胞在再生医学和组织工程修复中有着广泛的应用前景。牙髓干细胞在骨组织修复领域已进入临床研究阶段,而向其他组织分化的研究尚处于起步阶段或基础研究阶段,其调控机制存在着诸多问题,有着巨大的研究潜力。

 

摘要
背景:
牙髓干细胞是具有良好分化与增殖能力的干细胞,因其取材方便,具有多向分化潜能等特征正逐渐为再生医学研究领域重视。
目的:通过分析整理国内外牙髓干细胞的研究进展,对其目前在再生医学领域的应用研究加以总结,为进一步研究提供线索和方向。
方法:以“dental pulp stem cell, regenerative medicine, tissue engineering”为英文检索词,以“牙髓干细胞,再生医学,组织工程” 为中文检索词,由第一作者检索Medline,PubMed,万方,维普,中国知网数据库2000至2015年牙髓干细胞及再生医学相关文献,经过筛选最终获得46篇文献进行综述。
结果与结论:牙髓干细胞具有自我更新与多向分化潜能,获取方法简便,在再生医学领域拥有巨大发展潜能。牙髓干细胞在骨组织修复领域已进入临床研究阶段,在向其他组织分化方向的研究,尚处于起步阶段或基础研究阶段,有待进一步研究拓展。

Abstract:

BACKGROUND: Dental pulp stem cells are characterized by multi-lineage differentiation and proliferation abilities and are easy to obtain, so they are becoming an issue of concern in regenerative medicine.
OBJECTIVE: To provide clues and direction for further study by analyzing progress of domestic and overseas research on dental pulp stem cells, and summarizing their application in regenerative medicine.
METHODS: The “dental pulp stem cell, regenerative medicine, tissue engineering” in Chinese and English served as the search terms to search articles related to dental pulp stem cells and regenerative medicine, published from 2000 to 2015 in Medline, PubMed, CNKI, Wanfang and Cqvip databases. Totally 46 articles were selected for overview. 
RESULTS AND CONCLUSION: Dental pulp stem cells, which hold the capacity of self-renewal and multi-lineage differentiation, are relatively easy to obtain, and exhibit a great potential in regenerative medicine. The research of dental pulp stem cells in repairing bone defects has entered the clinical trial phase, but the research of cell differentiation into other tissues is still in basic trial phase and needs further development.
