Effect of Sm EVs on cell proliferation and migration in mucosal organoids. (A) Organoids derived from three oral mucosal tissues were treated with 107 particles/mL of Sm EVs for 7 days. Organoid morphology was monitored using phase-contrast microscopy. (B) Confocal microscopy images showing Ki67 (red) expression, a cell proliferation marker, in organoids treated with Sm EVs for 24 h. DAPI (blue) staining was used as a nuclear control (*p < 0.05).
