There are typographical errors in the legend of Figure 3 which should read:-

“Histological assessment of the retina in EAU. Sections of the retina were stained with hematoxylin and eosin, and evaluated for histological damage on 15 and 20 days post immunization. Representative H&E staining images of PBS (A1 and C1, 15 days; A2 and C2 20 days), MSC-exo (A3, 15 days; A4, 20 days), and FIB-exo (C3, 15 days; C4, 20 days) treated groups are shown. Results are expressed quantitatively as histopathological scores (B and D). Values are expressed as the mean ± SD of six rats (12 eyes) per group. *P < 0.05”.
