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.
