Fluorescent protein tdTomato formed a red filter within the retina in Chx10-Cre; Ai9 mice. (A,B) In Ai9 mice without Cre, the fluorescent tdTomato protein was not expressed in the retina. (C,D) In Chx10-Cre;Ai9 mice, tdTomato was expressed in the retina after the STOP sequence was deleted by Cre. (E) The retinas from Chx10-Cre;Ai9 mice appeared red after 3, 6, 9, and 12 h of exposure in room light under bright field microscopy. DAPI, 4′,6-diamidino-2-phenylindole. GCL, ganglion cell layer; INL, inner nuclear layer; ONL, outer nuclear layer.
