摘要:

文题释义:

牙源性间充质干细胞:间充质干细胞属于成体干细胞,是来源于发育早期中胚层具有高度自我更新和多向分化潜能的干细胞,牙源性间充质干细胞是来源于牙齿组织提取的间充质干细胞,具有再生和分化潜力好、免疫原性低的特点,因而成为牙周组织再生的种子细胞。

免疫调节:指免疫系统中的免疫细胞和免疫分子之间以及与其他系统如神经内分泌系统之间的相互作用,使得免疫应答以最恰当的形式使机体维持在最适当的水平。

背景:牙源性间充质干细胞可以从牙髓、牙周膜、脱落的乳牙、根尖乳头、牙囊、牙龈等不同组织分离获得。大量实验研究发现牙源性间充质干细胞对免疫细胞的作用可能取决于周围微环境、干细胞的组织来源以及免疫细胞制备类型等多种因素,并且已经证明激活的免疫细胞可以上调牙源性间充质干细胞的免疫调节活性,这种对牙源性间充质干细胞免疫调节的研究将为其在再生修复方面的应用奠定基础。

目的:对牙源性间充质干细胞免疫调节作用的研究进展进行综述。

方法:计算机检索中国生物医学文献数据库(CBM)、CNKI数据库、PubMed数据库以及Elsevier数据库的相关文献,检索词为“免疫调节,免疫系统,间充质干细胞,再生,口腔疾病,病原菌,牙齿组织”“immune regulation,immune system,mesenchymal stem cells,regeneration,oral diseases,pathogenic bacteria,dental-tissue”,通过查阅2000至2019年期间收录的牙源性间充质干细胞免疫调节方面的相关文章,包括综述、基础研究以及临床研究,阅读文题和摘要进行初步筛选,排除与文章主题不相关的文献,最终纳入88篇文献进行结果分析。

结果与结论:目前牙源性间充质干细胞已经得到了广泛的应用,但是关于牙源性间充质干细胞在应用中所起到的免疫调节作用还不是很清晰。牙源性间充质干细胞与免疫细胞之间的相互作用代表了一种机制,该机制有助于组织稳态和炎性疾病的研究。因此,基于免疫调节的策略可能是一种非常有前途的工具。文章综述了牙源性间充质干细胞与免疫细胞相互作用的复杂机制,并讨论了其介导的免疫调节作用在口腔疾病进展和口腔组织再生中的潜在意义。

Abstract:

BACKGROUND: Dental tissue-derived mesenchymal stem cells can be isolated from different tissues such as dental pulp, periodontal ligament, exfoliated deciduous teeth, apical papilla, dental follicle, gingiva and other tissues. A large number of experimental studies have found that the effect of dental tissue-derived mesenchymal stem cells on immune cells may depend on many factors such as the surrounding microenvironment, the tissue source of the stem cells and the type of immune cell preparation. Moreover, it has been proved that activated immune cells can up-regulate the immunomodulatory activity of dental tissue-derived mesenchymal stem cells, and this research on the immunomodulatory activity of dental tissue-derived mesenchymal stem cells will lay the foundation for its application in regenerative repair.

OBJECTIVE: To review the research progress of dental tissue-derived mesenchymal stem cells in immune regulation.

METHODS: A computer-based search of China Biology Medicine (CBM), CNKI, PubMed and Elsevier databases was performed, and the search terms included “immunomodulation; immune system; mesenchymal stem cells; regeneration; oral diseases; pathogenic bacteria; dental-tissue.” We reviewed related articles regarding the immunoregulation of dental tissue-derived mesenchymal stem cells published from 2000 to 2019, including reviews, basic research, and clinical research. Preliminary screening of reading titles and abstracts was performed to exclude documents that are not related to the topic of the article. Based on the inclusion and exclusion criteria, 88 articles were finally included for result analysis.

RESULTS AND CONCLUSION: In recent years, dental tissue-derived mesenchymal stem cells have been widely used, but the immunomodulatory effect of dental tissue-derived mesenchymal stem cells is not clear. The interaction between dental tissue-derived mesenchymal stem cells and immune cells represents a mechanism that contributes to the study of tissue homeostasis and inflammatory diseases. Therefore, immunomodulation-based strategies may be a very promising tool. This paper reviews the complex mechanism of the interaction between dental tissue-derived mesenchymal stem cells and immune cells and discusses the potential significance of its mediated immunoregulation in the progression of oral diseases and oral tissue regeneration.

Key words: mesenchymal stem cells, tissue regeneration, dental tissue, immunoregulation, peripheral blood mononuclear cells
