目的:研究人牙囊细胞白细胞介素-10(interleukin-10,IL-10)蛋白的表达及其对破骨细胞分化因子(receptor activator of nuclear factor kappa B ligand,RANKL)表达的影响。方法:采用组织块加胶原酶消化法培养人牙囊细胞,进行IL-10免疫组...目的:研究人牙囊细胞白细胞介素-10(interleukin-10,IL-10)蛋白的表达及其对破骨细胞分化因子(receptor activator of nuclear factor kappa B ligand,RANKL)表达的影响。方法:采用组织块加胶原酶消化法培养人牙囊细胞,进行IL-10免疫组化染色。25ng/mlIL-10作用于牙囊细胞0、1、3、6 h,用RT-PCR检测RANKL mRNA表达的变化。结果:人牙囊细胞IL-10表达阳性。25ng/ml IL-10降低人牙囊细胞RANKL的表达,且具有时间依赖性。结论:人牙囊细胞表达IL-10,IL-10通过降低人牙囊细胞RANKL的表达,在牙齿萌出过程中起重要的调控作用。展开更多
