text: Each specimen was graded on a semiquantitative scale: grade 1, strong staining in more than 80% of megakaryocytes; grade 2, strong staining in 50% to 80% of megakaryocytes; grade 3, strong staining in 20% to 50% of megakaryocytes; and grade 4, strong staining in less than 20% of megakaryocytes (Figure 1 ).
text: Phase-contrast microscopy showed that LSK cells cultured on OP9-DL1 cells, but not OP9-GFP, gave rise to large cells with cytoplasmic protrusions reminiscent of proplatelet production by megakaryocytes ( Figure 1 A).
