Extracellular Vesicles from BOEC in In Vitro Embryo Development and Quality.

ABSTRACT: To evaluate the effect of conditioned media (CM) and Extracellular Vesicles (EVs) derived from bovine oviduct epithelial cell (BOEC) lines on the developmental capacity of bovine zygotes and the quality of embryos produced in vitro, presumptive zygotes were cultured under specific conditions. In experiment 1, zygotes were cultured either on monolayers from BOEC extended culture (E), together with fresh BOEC suspension cells, or with BOEC-CM from fresh or E-monolayers. In experiment 2, EVs were isolated from BOEC-CM and characterized (150-200 nm) by Nanosight® and electron microscopy. Zygotes were cultured in the presence of 3x10(5) EVs/mL, 1.5x10(5) EVs/mL or 7.5x10(4) EVs/mL of fresh or frozen BOEC-EVs. In experiment 3, zygotes were cultured in absence of FCS but with EVs from BOEC-E that
