Abstract
- Background: Extracellular vesicles (EVs) contain thousands of proteins and nucleic acids, playing an important role in cell–cell communications. Sertoli cells have been essential in the testis as a "nurse cell". However, EVs derived from human Sertoli cells (HSerCs) have not been well investigated. Methods: EVs were isolated from HSerCs via ultracentrifugation and characterized by transmission electron microscopy, tunable resistive pulse sensing, and Western blotting. The cargo carried by HSerCs-EVs was measured via liquid chromatography-mass spectrometry and GeneChip miRNA Arrays. Bioinformatic analysis was performed to reveal potential functions of HSerCs-EVs. Results: A total of 860 proteins with no less than 2 unique peptides and 88 microRNAs with high signal values were identified in HSerCs-EVs. Biological processes related to molecular binding, enzyme activity, and regulation of cell cycle were significantly enriched. Specifically, many proteins in HSerCs-EVs were associated with spermatogenesis and regulation of immune system, including Septins, Large proline-rich protein BAG6, Clusterin, and Galectin-1. Moreover, abundant microRNAs within HSerCs-EVs (miR-638, miR-149-3p, miR-1246, etc.) had a possible impact on male reproductive disorders such as asthenozoospermia and oligozoospermia. Conclusions: Our study has shown that HSerCs-EVs contain diverse components such as proteins and microRNAs. Further research is required to evaluate HSerCs-EVs in spermatogenesis, which are underutilized but highly potent resources with particular promise for male infertility. [ABSTRACT FROM AUTHOR]
