Histological examination and corneal thickness evaluation between groups. (a, e and i) Corneas from control group mice with no injuries. Corneas from FK group mice (b, f and j) and vehicleinj FK group mice (c, g and k) exhibited corneal thickening, irregularly aligned collagen fibers and extensive inflammatory cells infiltration. (d, h and i) Corneas from uMSCsinj FK group showed less corneal thickness, relative normal structural arrangement, and fewer inflammatory cells infiltration. (m) Statistical analysis of average corneal thickness (μm) between groups. Values are presented as means ± SD, n = 6, *P < 0.05. Scale bar, 100 μm
