Abstract

Our studies show that although interleukin 4 (IL-4) fails to stimulate significant colony formation by bone marrow progenitor cells, it enhances erythroid, granulocyte, macrophage, and mast-cell colony formation when used as a costimulant with erythropoietin, granulocyte colony-stimulating factor, macrophage colony-stimulating factor, and interleukin 3 (IL-3), respectively. In contrast, IL-4 suppresses IL-3-dependent colony formation by granulocyte and macrophage progenitor cells and by multipotential progenitor cells. Furthermore, it appears to inhibit the in vitro generation of colony-forming progenitor cells from immature IL-3-dependent stem cells. We also found that IL-4 inhibits stromal cell-dependent growth of bone marrow-derived pre-B cells. The ability of IL-4 to directly or indirectly regulate both positive and negative aspects of progenitor cell growth is discussed.

摘要

我们的研究表明,虽然白细胞介素4(IL-4)不能刺激骨髓祖细胞形成显著的集落,但当它分别与促红细胞生成素、粒细胞集落刺激因子、巨噬细胞集落刺激因子和白细胞介素3(IL-3)共同刺激时,可增强红系、粒细胞、巨噬细胞和肥大细胞集落的形成。相比之下,IL-4抑制粒细胞和巨噬细胞祖细胞以及多能祖细胞依赖IL-3的集落形成。此外,它似乎还能抑制未成熟的依赖IL-3的干细胞在体外生成集落形成祖细胞。我们还发现,IL-4抑制骨髓来源的前B细胞依赖基质细胞的生长。文中讨论了IL-4直接或间接调节祖细胞生长的正负两个方面的能力。
