本研究观察了白细胞介素-6(IL-6)对无血清培养体系中小鼠巨核细胞生成的影响。向含有白细胞介素-3(IL-3)的培养物中添加IL-6导致正常小鼠骨髓细胞的巨核细胞集落数量显著增加。暴露于5-氟尿嘧啶(5-FU)后存活的巨核细胞祖细胞对IL-6和IL-3表现出更显著的反应。多克隆抗IL-6抗体中和IL-6对IL-3支持的巨核细胞集落生长的刺激作用。胚细胞集落的延迟添加实验和再铺板实验表明,巨核祖细胞在发育的早期阶段由IL-3支持,但其随后的增殖和分化需要IL-6。此外,IL-6增加粒细胞-巨噬细胞-巨核细胞集落中巨核细胞的大小。粒细胞集落刺激因子或粒细胞-巨噬细胞集落刺激因子与IL-3联合应用可分别促进5-FU处理小鼠或正常小鼠骨髓细胞的粒细胞-巨噬细胞集落生长,但对单纯巨核细胞集落和混合巨核细胞集落生长的促进作用不大。提示IL-6在小鼠巨核细胞生成中起重要作用。
We investigated the effect of interleukin-6 (IL-6) on murine megakaryocytopoiesis in a serum-free culture system. The addition of IL-6 to a culture containing interleukin-3 (IL-3) resulted in a significant increase in the number of megakaryocyte colonies by bone marrow cells of normal mice. The megakaryocytic progenitors that survive exposure to 5-fluorouracil (5-FU) exhibited a more significant response to IL-6 and IL-3. Polyclonal anti-IL-6 antibody neutralized the stimulatory effect of IL-6 on megakaryocyte colony growth supported by IL-3. Delayed addition experiments and replating experiments of blast cell colonies showed that megakaryocytic progenitors are supported by IL-3 in the early stage of the development but require IL-6 for their subsequent proliferation and differentiation. In addition, IL-6 increased the size of megakaryocytes in granulocyte-macrophage-megakaryocyte colonies. The combination of granulocyte colony-stimulating factor or granulocyte-macrophage colony stimulating factor with IL-3 resulted in an increase in the granulocyte-macrophage colony growth of bone marrow cells of 5-FU-treated mice or normal mice, respectively, but had little effect on the enhancement of pure and mixed megakaryocyte colony growth. These results suggest that IL-6 plays an important role in murine megakaryocytopoiesis.
