Figure 1: NXT inhibits the accumulation of carbohydrate macromolecules and the formation of acellular capillaries in retinal vasculature in mice. (a) At the end of the study, mouse eyes were collected and the retinal vascular network was prepared followed by PAS staining and photograph under a microscope as described in Section 2. The representative images from each group were presented. Black arrows indicate acellular capillaries in the retinal vasculature. Bars: 1 mm and 50 μm in the up and middle panels, respectively. (b) The density of PAS staining was quantified by the Photoshop software. (c) Quantitation of acellular capillaries in the retina. ().
