使用多色流式细胞仪进行非同位素配体结合测定,我们定量检测了巨核细胞-血小板谱系细胞中的 mpl 量。首先,我们量化了细胞系上的 mpl 量。转染mpl基因的BaF3细胞表达大量mpl,而原始BaF3、K562、HL-60和NOMO-1细胞则不表达mpl。在健康志愿者的骨髓细胞中,mpl 在分化的早期阶段就在 CD34+ 细胞上表达,当时这些细胞没有 CD38 抗原。 mpl的量随着分化为CD34+CD41+细胞而增加,但随着进一步分化为CD34−CD41+细胞而减少。在CD34+CD41+细胞中,mpl的量根据细胞大小而变化:大细胞中丰富,中型细胞中中等,小细胞中少量。
Using a non‐isotopic ligand binding assay using multi‐colour flow cytometry, we quantitatively examined the amount of mpl in megakaryocyte‐platelet lineage cells. Firstly, we quantified the amount of mpl on cell lines. Mpl gene‐transfected BaF3 cells expressed a large amount of mpl, whereas original BaF3, K562, HL‐60 and NOMO‐1 cells showed no mpl. In bone marrow cells from healthy volunteers, mpl was expressed on CD34+ cells from the very early stage of differentiation when they had no CD38 antigen. The amount of mpl increased with differentiation to CD34+CD41+ cells, but decreased with further differentiation to CD34−CD41+ cells. In CD34+CD41+ cells the amount of mpl varied according to cell size: abundant in large cells, moderate in medium‐size cells and a little in small cells.
