Visualization of Ly6Chi monocytes in Cx3cr1gfp/+ mice with an anti-Ly6B.2 antibody. Time-lapse image sequence of maximum intensity projection displaying the behavior of GFP+ cells in the lungs (alveolar space) of Cx3cr1gfp/+ mice. Evans blue (50 µg) was administered i.v. to delineate the lung vasculature. 5 min after the beginning of imaging, Ly6B.2-PE (4 µg) was injected i.v., and allowed the visualization of Ly6Chi monocytes (Ly6B.2+CX3CR1+), Ly6Clo monocytes (Ly6B.2−CX3CR1+) and neutrophils (Ly6B.2+CX3CR1−). Video is representative of 3 mice. Elapsed time is shown as hours:minutes:seconds. Scale bar: 40 µm.
