摘要:

背景:因巨噬细胞在机体炎症反应中有着举足轻重的作用,所以检测生物材料对巨噬细胞行为的影响,可评估材料的免疫原性。
目的:分析脱细胞基质材料对巨噬细胞的激活作用。
方法:获取BALB/c小鼠腹腔巨噬细胞,分5组培养:对照组为单纯细胞培养组;实验1组为脱细胞基质膜材料与巨噬细胞直接接触培养,实验2组为新鲜心包膜材料与巨噬细胞直接接触培养,实验3组为脱细胞基质膜材料与巨噬细胞间接接触培养,实验4组为新鲜心包膜材料与巨噬细胞间接接触培养。培养48 h后,MTT法检测各组A值,判定毒性分级;培养24 h后,检测细胞培养上清中一氧化氮及细胞因子的分泌。
结果与结论:实验1-4组毒性分别为2级、4级、0级及2级。实验1组、实验2组一氧化氮水平高于对照组(P < 0.05),并且实验2组高于实验1组(P < 0.05)。5组间白细胞介素2、白细胞介素4、干扰素γ、白细胞介素17A和白细胞介素10水平比较差异无显著性意义;实验2组白细胞介素6水平高于对照组(P < 0.05);实验1组、实验2组、实验4组肿瘤坏死因子水平高于对照组(P < 0.05),并且实验2组高于实验1组(P < 0.05)、实验1组高于实验4组(P < 0.05)。说明脱细胞基质材料可在直接接触时激活巨噬细胞。

Abstract:

BACKGROUND: Because macrophages play an important role in the body’s inflammatory response, the detection of the impact of biological materials on the behavior of macrophages can assess the immunogenicity of materials.

OBJECTIVE: To analyze the activation effect of decellularized extracellular matrix materials on macrophages.
METHODS: The peritoneal macrophages of BALB/c mouse were obtained and cultured by dividing into five groups. Control group was simple cell culture group, experimental group 1 was acellular matrix membrane material directly contacting with macrophage for culture, experimental group 2 was fresh pericardial material directly contacting with the macrophage for culture, experimental group 3 was acellular matrix membrane material indirectly contacting with macrophages for culture, experimental group 4 was fresh pericardium material indirectly contacting with macrophages for culture. After 24 hours of culture, the secretion of nitric oxide and cytokines in cell culture supernatant was determined. After 48 hours of culture, the absorbance value was determined by MTT method and the toxicity grading was determined.
RESULTS AND CONCLUSION: The toxicity grading in experimental groups 1-4 was respectively grades 2, 4, 0, 2. The nitric oxide level in experimental groups 1 and 2 was higher than that in the control group (P < 0.05), and the nitric oxide level in the experimental group 2 was higher than that in the experimental group 1 (P < 0.05). There were no significant differences in interleukin-2, interleukin-4, interferon γ, interleukin-17A and interleukin-10 levels between these five groups. The interleukin-6 level in the experimental group 2 was higher than that in the control group (P < 0.05); The expression levels of tumor necrosis factors in experimental group 1, 2 and 4 were higher than those in the control group (P < 0.05), and experimental group 2 higher than the experimental group 1 (P < 0.05), experimental group 1 higher than the experimental group 4 (P < 0.05). These results show that acellular matrix material can activate macrophages in direct contact.
