Enhanced exosome release from podocytes after Hcy and dependence on ROS and NADPH oxidase. A. Representative images showing exosome release from different groups of podocytes. The x axis is diameter (nm); the y axis is concentration; the z axis is intensity (a.u.). B. Summarized data showing exosome release from different groups of podocytes (n = 6). *p < 0.05 vs. Vehl group, #p < 0.05 vs. Ctrl group. Ctrl, control; Vehl, vehicle; gp91 ds-tat, gp91 ds-tat peptide; Hcy, homocysteine.
