Human BFU-E–derived cells, HL-60 cells, and UT-7 cells express PSGL-1 (CD162) and become covered with PMPs after incubation with platelets.

Normal human BFU-E–derived cells (upper row), HL-60 cells (middle row), and UT-7 cells (lower row) were stained with PE–anti-PSGL-1 monoclonal antibody (left panels) and PE–anti-CD41 monoclonal antibody before (middle panels) or after (right panels) incubation with platelets. One study representative of 3 is shown.
