通过使用特定的酶联免疫吸附测定,作者证明人骨髓基质细胞产生 IL-6 和 IL-8。在用脂多糖(LPS)和佛波醇肉豆蔻酸酯乙酸酯(PMA)刺激后,它们的合成以剂量依赖性方式增强。 PKC 抑制剂十字孢菌素显着减少了 PMA 产生的白细胞介素 6 (IL-6) 和 IL-8 的产生。培养基中含有 0% 和 10% 胎牛血清 (FCS) 时,IL-6 (10 ng/ml) 可刺激 IL-8 产生。在类似条件下,IL-8 (10 ng/ml) 增强了 IL-6 的产生。 IL-1 α、IL-1 β 和 IL-3、肿瘤坏死因子 α (TNF-α)、干细胞因子 (SCF) 和粒细胞巨噬细胞集落刺激因子 (GM-CSF)(10 ng/ml)刺激 0% 和 10% FCS 中 IL-6 和 IL-8 的产生。在 10% FCS 中,G-CSF 刺激 IL-8 产生,而 IL-4 抑制 IL-8 产生。 IL-2、IL-4 和 bFGF 刺激 0% FCS 中 IL-6 的产生。这些结果表明,骨髓基质细胞可能是人骨髓内细胞因子调节的局部产生 IL-6 和 IL-8 的主要来源。
By using a specific enzyme-linked immunosorbent assay, the authors demonstrated that human bone marrow stromal cells produce IL-6 and IL-8. Their synthesis is enhanced in a dose-dependent manner after stimulation with lipopolysaccharide (LPS) and phorbol myristate acetate (PMA). Interleukin 6 (IL-6) and IL-8 production in response to PMA were markedly diminished by the PKC inhibitor staurosporine. IL-6 (10 ng/ml) stimulated IL-8 production with 0% and 10% fetal calf serum (FCS) in the culture medium. In similar conditions, IL-8 (10 ng/ml) enhanced IL-6 production. IL-1 alpha, IL-1 beta, and IL-3, tumour necrosis factor alpha (TNF-alpha), Stem cell factor (SCF) and granulocyte-macrophage colony-stimulating factor (GM-CSF) (at 10 ng/ml) stimulated IL-6 and IL-8 production in 0% and 10% FCS. G-CSF stimulated and IL-4 inhibited IL-8 production in 10% FCS. IL-2, IL-4 and bFGF stimulated IL-6 production in 0% FCS. These results suggest that bone marrow stromal cells might represent a major source for the cytokine-regulated local production of IL-6 and IL-8 inside human bone marrow.
