Abstract
Porcine seminal plasma (SP) is loaded with a heterogeneous population of extracellular vesicles (sEV (show more...)Porcine seminal plasma (SP) is loaded with a heterogeneous population of extracellular vesicles (sEVs) that modulate several reproductive-related processes. This study investigated the effect of two sEV subsets, small (S-sEVs) and large (L-sEVs), on porcine in vitro fertilization (IVF). The sEVs were isolated from nine SP pools (five ejaculates/pool) using a size-exclusion chromatography-based procedure and characterized for quantity (total protein), morphology (cryogenic electron microscopy), size distribution (dynamic light scattering), purity and EV-protein markers (flow cytometry/ albumin, CD81, HSP90β). The characterization confirmed the existence of two subsets of high purity (low albumin content) sEVs that differed in size (S- and L-sEVs). In vitro fertilization was performed with in vitro matured oocytes and frozen-thawed spermatozoa and the IVF medium was supplemented during gamete coincubation (1 h at 38.5 °C, 5 % CO in a humidified atmosphere) with three different concentrations of each sEV subset: 0 (control, without sEVs), 0.1, and 0.2 mg/mL. The first experiment showed that sEVs, regardless of subset and concentration, decreased penetration rates and total IVF efficiency (P < 0.0001). In a subsequent experiment, it was shown that sEVs, regardless of subset and concentration, impaired the ability of spermatozoa to bind to the zona pellucida of oocytes (P < 0.0001). The following experiment showed that sEVs, regardless of the subset, bound to frozen-thawed sperm but not to in vitro matured oocytes, indicating that sEVs would affect sperm functionality but not oocyte functionality. The lack of effect on oocytes was confirmed by incubating sEVs with oocytes prior to IVF, achieving sperm-zona pellucida binding results similar to those of control. In the last experiment, conducted under IVF conditions, sperm functionality was analyzed in terms of tyrosine phosphorylation, acrosome integrity and metabolism. The sEVs, regardless of the subset, did not affect sperm tyrosine phosphorylation or acrosome integrity, but did influence sperm metabolism by decreasing sperm ATP production under capacitating conditions. In conclusion, this study demonstrated that the presence of sEVs on IVF medium impairs IVF outcomes, most likely by altering sperm metabolism. (hide)

Hardware adaptation to ~100nm EV's
The optical setup of the flow cytometer was modified to use the side scatter (SSC) information of the 405 nm laser (violet-SSC-A) instead of the 488 nm laser. The SSC was then calibrated using polystyrene beads of known diameter between 80 and 300 nm with a density of 1,05 g/cm_ and a refractive index of 1.59 nm (Cat 30080A, 30100A, 30200A and 30300A, Nanosphere serie 3000/ Thermofisher Scientific, Waltham, Massachusetts, USA). The forward scatter (FSC) and violet SSC-A were corrected on a logarithmic scale and the fluorescence channels were corrected on a logarithmic gain. The EV detection region was then set for events with size (by FSC) and complexity (by violet-SSC-A) characteristics of EVs. The SSC data generated by beads were fitted to nm according to Mie theory, using FCMPASS software (https://nano.ccr.cancer.gov/fcmpass/). Commercially available recombinant exosomes expressing green fluorescent protein (GFP) on their membrane surface (SAE0193, Merck) with a size distribution ranging from 30 to 200 nm (peak at 100-150 nm, measured by DLS) were used to validate the accuracy of the flow cytometer for the analysis of sEVs.

The optical setup of the flow cytometer was modified to use the side scatter (SSC) information of the 405 nm laser (violet-SSC-A) instead of the 488 nm laser. The SSC was then calibrated using polystyrene beads of known diameter between 80 and 300 nm with a density of 1,05 g/cm_ and a refractive index of 1.59 nm (Cat 30080A, 30100A, 30200A and 30300A, Nanosphere serie 3000/ Thermofisher Scientific, Waltham, Massachusetts, USA). The forward scatter (FSC) and violet SSC-A were corrected on a logarithmic scale and the fluorescence channels were corrected on a logarithmic gain. The EV detection region was then set for events with size (by FSC) and complexity (by violet-SSC-A) characteristics of EVs. The SSC data generated by beads were fitted to nm according to Mie theory, using FCMPASS software (https://nano.ccr.cancer.gov/fcmpass/). Commercially available recombinant exosomes expressing green fluorescent protein (GFP) on their membrane surface (SAE0193, Merck) with a size distribution ranging from 30 to 200 nm (peak at 100-150 nm, measured by DLS) were used to validate the accuracy of the flow cytometer for the analysis of sEVs.

Abstract
Porcine seminal plasma (SP) is loaded with a heterogeneous population of extracellular vesicles (sEV (show more...)Porcine seminal plasma (SP) is loaded with a heterogeneous population of extracellular vesicles (sEVs) that modulate several reproductive-related processes. This study investigated the effect of two sEV subsets, small (S-sEVs) and large (L-sEVs), on porcine in vitro fertilization (IVF). The sEVs were isolated from nine SP pools (five ejaculates/pool) using a size-exclusion chromatography-based procedure and characterized for quantity (total protein), morphology (cryogenic electron microscopy), size distribution (dynamic light scattering), purity and EV-protein markers (flow cytometry/ albumin, CD81, HSP90β). The characterization confirmed the existence of two subsets of high purity (low albumin content) sEVs that differed in size (S- and L-sEVs). In vitro fertilization was performed with in vitro matured oocytes and frozen-thawed spermatozoa and the IVF medium was supplemented during gamete coincubation (1 h at 38.5 °C, 5 % CO in a humidified atmosphere) with three different concentrations of each sEV subset: 0 (control, without sEVs), 0.1, and 0.2 mg/mL. The first experiment showed that sEVs, regardless of subset and concentration, decreased penetration rates and total IVF efficiency (P < 0.0001). In a subsequent experiment, it was shown that sEVs, regardless of subset and concentration, impaired the ability of spermatozoa to bind to the zona pellucida of oocytes (P < 0.0001). The following experiment showed that sEVs, regardless of the subset, bound to frozen-thawed sperm but not to in vitro matured oocytes, indicating that sEVs would affect sperm functionality but not oocyte functionality. The lack of effect on oocytes was confirmed by incubating sEVs with oocytes prior to IVF, achieving sperm-zona pellucida binding results similar to those of control. In the last experiment, conducted under IVF conditions, sperm functionality was analyzed in terms of tyrosine phosphorylation, acrosome integrity and metabolism. The sEVs, regardless of the subset, did not affect sperm tyrosine phosphorylation or acrosome integrity, but did influence sperm metabolism by decreasing sperm ATP production under capacitating conditions. In conclusion, this study demonstrated that the presence of sEVs on IVF medium impairs IVF outcomes, most likely by altering sperm metabolism. (hide)
