Abstract (original English)
Background Extracellular vesicles (EVs) regulate cell metabolism and various biological processes by delivering specific proteins and nucleic acids to surrounding cells. We aimed to investigate the effects of the cargo contained in EVs derived from adipose-derived stem cells (ASCs) on the porcine embryonic development. Methods ASCs were isolated from porcine adipose tissue and characterized using ASC-specific markers via flow cytometry. EVs were subsequently extracted from the conditioned media of the established ASCs. These EVs were added to the in vitro culture environment of porcine embryos to observe qualitative improvements in embryonic development. Furthermore, the proteins within the EVs were analyzed to investigate the underlying mechanisms. Results We observed a higher blastocyst development rate and increased mitochondrial activity in early stage embryos in the ASC-EVs-supplemented group than in the controls (24.8% ± 0.8% vs. 28.6% ± 1.1%, respectively). The terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay of blastocysts also revealed significantly reduced apoptotic cells in the ASC-EVs-supplemented group. Furthermore, through proteomics, we detected the proteins in ASC-EVs and blastocysts from each treatment group. This analysis revealed a higher fraction of proteins in the ASC-EVs-supplemented group than in the controls (1,547 vs. 1,495, re
