Fig. 6. Effect of PF on the detachment of corneal epithelial cells. The corneas of mice were stained with H&E before induction with HM, 28 days after treatment with PF eye drops (A). The black arrows indicate detached corneal epithelial cells. Scale bar = 50 μm. (B) The number of detached corneal epithelial cells is expressed as the mean ± the SD (n = 4–5 eyes). *P < 0.05 compared with the control group. ^†P < 0.01 compared with the HM-stimulated group.
