GAP43 expression representing the regenerated ON fibers in each group. A Time course of treatment for each group of animals. ON, optic nerve. B Representative photomicrographs showing the injury site and regenerating axons via GAP 43 (red, 594) immunofluorescence staining. Yellow * stands for ONI site. Scale bar: 500 μm. C Bar charts showing the regenerating axons on the right of the ONI site in each group. ONI: optic nerve injury, *p ˂ 0.05, **p ˂ 0.01, n = 4. The student’s t-test was used
