Surface-rendered platelet projection. (A) A representative hTg^WT platelet is shown after image analysis reveals the surface-rendered fluorescence from anti-CD41 antibodies. The stack confocal image of this platelet is visible in Figure 1A within the circle. (B) If the CD41-dependent fluorescence intensity is decreased, the internal VWF⁺ α-granules are readily visible filling the platelet interior.
