(A) Representative transmission electron microscopy of circulating human EVs from control (hEVCT) and STEMI patients (hEVSTEMI). (B) Representative WB of circulating EVs (30 μg total protein/lane). Heart lysates were used as control. (C) Levels of Cx43 were evaluated in hEVCT and hEVSTEMI. Individual levels, median, and interquartile range are plotted on graph (n = CT, n = 28 STEMI). (D) WB analysis of Cx43, Alix, Hsp90, and GAPDH in circulating EVs (30 μg total protein/lane). (E) Permeability of EV-Cx43 channels in circulating vesicles from human controls, assessed by sucrose-based transport-specific density shift.
