There was no interaction between Ly6Clow monocytes and platelets in the steady state. Shown is confocal intravital microscopy of mesenteric vein in the steady state. Ly6Clow monocytes are shown by GFP (green). Platelets were labeled with i.v. injected PE-conjugated anti-CD49b antibody (1 μg, red). Movie duration is 3 min. (Scale bar: 10 μm.) (See Fig. 5.)
