A. Retinal whole mount immunostaining for Isolectin-B4 (red) and Desmin (green) in WT (top panel) and Glut1iECKO (bottom panel) mice showing pericyte coverage in the vasculature. Left and right panels show representative images with 20x or 63x magnification, respectively. B. Quantification of the pericytes coverage in the retinal vasculature of WT (blue) and Glut1iECKO (orange) mice. (n=9 from 3 independent experiments. Error bars indicate the standard error of the mean (SEM) from unpaired Student's t test.)
