LSPCs exerted neuroprotective effects in light exposure-induced retina. IHC was carried out to examine the expression of GFAP protein in retinal tissues. Representative photos of IHC assay of retinal sections for control, light-induced retinal damage model, low-, medium-, and high-dose LSPCs groups are separately shown. Magnification, 100× or 200× bar value, 50 or 100 μm. Olympus software (version 2.2; Olympus, Japan) was used to create the pictures.
