The present study examined glucose transfer in the cellular scale of mouse brain microvasculature in vivo using two-photon microscopy and fl uorescent glucose analogue (2-NBDG). The 2-NBDG was intravenously injected (0.04 mL/ min) in the anesthetized Tie2-GFP mice in which the vascular endothelium expressed fl uorescent protein. Time-lapse imaging was conducted on the cortical parenchyma, while the time–intensity change of the injected 2-NBDG was analysed in respective vascular compartments (artery, capillary, and vein). We observed that 2-NBDG signal increased monotonically in the vasculature during the period of the injection, and rapidly declined following its cessation. In tissue compartment, however, the signal intensity gradually increased even after cessation of the injection. Spatiotemporal analysis of the 2-NBDG intensity over the cross-sections of the vessels further showed distinct change of the 2-NBDG intensity across the vessel wall (endothelium), which may represents a regulation site of tissue glucose infl ux.
