FIGURE 6.
CD19-Cre does not label osteoclasts in vivo. Shown are fluorescence and bright field microscopy images of histological frozen sections of lumbar vertebra from LysM-Cre;tdTomato mice, tdTomato mice, and CD19-Cre;tdTomato mice. Images on the left are fluorescence showing tdTomato-positive cells in bone and bone marrow. Images on the right are brightfield images of the same sections after staining for TRAP activity. Scale bar, 20 μm.
