Mice lacking the visual cycle enzymes RPE65 or lecithin-retinol acyl transferase (Lrat) have pupillary light responses (PLR) that are less sensitive than those of mice with outer retinal degeneration (rd/rd or rdta). Inner retinal photoresponses are mediated by melanopsin-expressing, intrinsically photosensitive retinal ganglion cells (ipRGCs), suggesting(More)
Mammary stem cells (MaSCs) play essential roles for the development of the mammary gland and its remodeling during pregnancy. However, the precise localization of MaSCs in the mammary gland and their regulation during pregnancy is unknown. Here we report a transgenic mouse model for luciferase-based single marker detection of MaSCs in vivo that we used to(More)
PURPOSE Mice lacking rods and cones retain pupillary light reflexes that are mediated by intrinsically photosensitive retinal ganglion cells (ipRGCs). Melanopsin is necessary and sufficient for this nonvisual photoreception. The mammalian inner retina also expresses the potential blue light photopigments cryptochromes 1 and 2. Previous studies have shown(More)
