Figure 1.
Direct intrafemoral injection procedure. One or both hind limbs of anesthetized mice were injected by DII with 30 μL PKH-26 dye at a concentration of 1 × 10-5 M. Bone marrow from injected femurs was harvested and analyzed for PKH-26 labeling by fluorescence microscopy (original magnification, × 400). The data shown are representative of 3 separate experiments.
