A, B Fluorescence imaging of the ability of CBCY5.5-NPs and CBCY5.5-LepR to target LepR+ cells after FITC-conjugated secondary antibody labeling of LepR+ cells in femoral sections from the aged mice. Scale bars, 500 μm (red) and 50 μm (white). C, D Schematic diagram and representative fluorescence images of CBFITC-LepR-targeted LepR+ cells in LepR-tdTomato mice. Scale bar, 50 μm.
