ABSTRACT
Embryonic stem cells (ESCs) have the ability to differentiate into various adult cells, and their fate in the process of development and differentiation is determined by the comprehensive regulation of multiple factors such as gene expression, epigenetics, and extracellular signals. Epigenetic regulation, such as DNA methylation, histone acetylation, and methylation, plays an important role in the maintenance of pluripotency and differentiation of ESCs. Suds3 (Sin3 histone deacetylase corepressor complex component SDS3) is one of the important components of Sin3 histone deacetylase complex. It played an important role in embryonic development, cell proliferation, chromosome separation and other biological processes. However, the functions of Suds3 in ESCs, such as its influence on the proliferation, maintenance of pluripotency and differentiation of ESCs, were rarely reported. In this study, we used CRISPR/Cas9 gene editing technology to construct a Suds3 knockout mouse embryonic stem cell line, and combined cell culture, in vitro embryoid body (EB) formation and in vivo teratoma formation, CCK-8 and cell counting experiments to study the function of Suds3 in ESCs. Western blotting results showed that the SUDS3 protein was not expressed, and the Suds3 gene was successfully knocked out. Through the observation of cell morphology and fluorescence quantitative PCR (QRT-PCR) to detect the expression of pluripotency genes, we found that the knockout of Suds3 had no significant effect on the maintenance of pluripotency of ESCs. Embryoid body (EB) formation experiments revealed that on the fourth and sixth days of EB formation, the pluripotency gene expression was not down-regulated as quickly as WT cells but increased in Suds3
