Expression profiles of OPN1SW and GFAP in the control and atrophic retina. (A) DAPI staining demonstrated the organized and distorted retina in the control and atrophic eyes. (B) OPN1SW staining revealed intact S cone outer segment in the control, but absent expression in the atrophic retina. (C) GFAP staining showed restricted signal of activated Müller cells in the control eye, whereas expanded signal of activated Müller cells was detected in the atrophic retina. (D) Merged images for the control and atrophic retinal tissues. Scale bar=50 µm. CON, control; RD, retinal detachment; ONL, outer nuclear layer; INL, inner nuclear layer; GCL, ganglion cell layer; DAPI, 4′,6-diamidino-2-phenylindole; OPN1SW, short-wave-sensitive opsin 1; GFAP, glial fibrillary acidic protein.
