摘要:

文题释义:

干细胞:是一类具有自我更新、自我复制和多向分化潜能的细胞群体,这些干细胞可通过诱导进一步分化成多种功能细胞,具有再生各种组织器官的潜在功能。干细胞按种类可以分为全能干细胞、多能干细胞和单能干细胞。

单细胞分析技术:能通过相应技术分离与提取单个靶细胞,利用基因组扩增、测序等技术对靶细胞内的基因组信息、蛋白信息进行分析,能准确地提供细胞内物质及生化反应的准确信息,能够反映细胞的功能与化学组分的特定关系与某些细胞在生命体内的特殊作用。

背景:通过单细胞分析可以揭示各种干细胞的组成、生理行为与功能的多样性、差异性。随着干细胞治疗逐渐走向临床应用,相伴而来的异质性问题尤为凸显并成为制约其发展的关键,使针对各种干细胞的单细胞分析技术越来越受科学家们的重视。

目的:总结单细胞分离与收集技术和单细胞分析技术在干细胞异质性研究的进展与应用。

方法:((stem cell) OR (human pluripotent stem cells) OR (hPSCs)) AND (single cell analysis technology)”为英文检索词,以“干细胞,单细胞分析”为中文检索词,由第一作者检索19902019PubMed数据库、中国知网、万方全文数据库,查阅近年单细胞分析技术在干细胞领域中应用的相关文献,最终保留57篇进行综述。

结果与结论:干细胞的异质性问题是阻碍干细胞进入临床治疗的关键,因此通过单细胞分析了解干细胞的异质性至关重要。随着单细胞高通量技术的发展,新一代单细胞的分离和检测技术将使人们能够更加全面了解单细胞。微流体装置的多功能性和控制精度得到了极大的改善,未来将对干细胞领域的单细胞分析发挥很大作用。而单细胞机器人作为一门高通量筛选的新兴技术,在操作上较微流体技术更简便,深受科学家们的重视。

Abstract:

BACKGROUND: Single cell analysis of stem cells can reveal the composition and physiological behavior diversity and diversity of various stem cells. As stem cell therapy gradually moves into clinical applications, the accompanying heterogeneity problem is particularly prominent and becomes the key to its development. Therefore, single cell analysis technique for various stem cells has attracted increasing attention.

OBJECTIVE: To summarize the single cell isolation and collection technology and progress and application of single cell analysis technology in stem cell heterogeneity research.

METHODS: PubMed database was searched for relevant articles published from 1990 to 2019 using the keywords of “(stem cell OR (human pluripotent stem cells) OR (hPSCs)) AND (single cell analysis technology). CNKI and WanFang were retrieved for relevant articles published from 1990 to 2019 using the keywords of “stem cells, single cell analysis” in Chinese. The articles concerning the single cell analysis technique in recent years were reviewed, and finally 57 eligible articles were included for result analysis.

RESULTS AND CONCLUSION: Stem cell heterogeneity is the key to blocking the use of stem cells in clinical treatment. Therefore, understanding the heterogeneity of stem cells through single cell analysis is crucial. With the development of single cell high-throughput technology, a new generation of single cell separation and detection technologies will enable people to fully understand single cells. The versatility and control accuracy of the microfluidic device have been significantly improved, and will play a significant role in the analysis of single cells in the stem cells. As a new technology for high-throughput screening, single-cell robots are easier to operate than microfluidics and are highly valued by scientists. 

Key words: stem cells,  heterogeneity,  single cell,  analysis,  technology
