摘要
目的:探讨巨噬细胞集落刺激因子(M-CSF)、白细胞介素-1(IL-1)和肿瘤坏死因子α(TNF-α)在骨巨细胞瘤(GCT)形成及其溶骨中的作用。方法:运用免疫组化方法和细胞培养技术,观察M-CSF、IL-1和TNF-α在18例GCT中的表达及其对GCT溶骨的影响。结果:在GCT中,M-CSF主要由纤维母细胞样基质细胞(FC)分泌;巨噬细胞样基质细胞(HC)主要分泌IL-1和TNF-α,少数多核巨细胞(MGC)也可产生TFN-α。外源性的TNF-α。外源性的能加强GCT中FC对骨质的破坏。结论:GCT中HC和MGC分泌的IL-1和TNF-α,可以刺激FC的溶骨和浸润性的生长,从而增强GCT侵袭性的生物学行为。而FC产生的M-CSF可能促进厂GCF中MGC的形成。
Purpose:To investigate the role of Macrophage colonstimulating factors (M-CSF),Interleukin (IL-1)and Tumor necrosis factor-a in the formation of giant cell tumor (GCT) of bone and it's bone resorption.Method:Immunohistichemical method and Cell culture technique was used to detect the expression and bone resorpted function of Histocyte like stromal cells (cH)had the abilith to secrtle IL-1 and TNF-a Some of the multinuclated cells (MGC) GCF the cjytokines of TNF-a and IL-1 that secreted by HC and MGC could stumulate bone resortion of FC and it's invasive growth ,as to enhance GCT's invading biologyial behaviors.The production of M-CSF byFC might play a role in the formation of MGC in GCT.
