Figure 1.
No overt loss of yellow fluorescent protein (YFP)-positive cells in the retinal ganglion cell (RGC) layer over time post-injury. These retinal whole mounts demonstrate similar YFP distribution in the sham and injured (Inj) animals at 2, 7, 14 and 28 days post-traumatic brain injury. The axons in the retina remain intact without any axonal swellings. The center and middle regions of the retina reveal no overt loss of YFP-positive cells in the RGC layer (the same layer as RGC axons) over time after injury. Scale bar: 100 μm.
