Figure 3. Cells exposed to H₂O₂ show an increase in oxidized proteins, whereas exosomes do not.

Oxidized proteins (% intensity) in MC/9 cells (a) and their released exosomes (b) after exposure to vehicle or H₂O₂ (125 µM) for 24 h (n = 5). Oxidative stress significantly increased the relative amount of oxidized proteins in cells, but did not significantly affect the relative amount of oxidized proteins in exosomes. *p<0.05.
