摘要 目的观察脂肪干细胞(ADSCs)与异同种异体树突状细胞(DC)共培养后,DC细胞发生的耐受和Th1的极化情况。方法ADSCs与同种异体的DC共同培养3d后,通过流式细胞仪对共刺激分子的表达进行检测,用ELISA法对细胞因子的产生白细胞介素12(IL-12)和肿瘤坏死因子α(TNF—α)做进一步地分析。结果ADSCs和DC共同培养前CD80、CD83、CD86分别为(92.1±2.1)%、(90.4±8.3)%、(87.9±4.5)%,共同培养后分别为(76.2±5.1)%、(67.4±3.3)%、(57.1±3.2)%,差异均有统计学意义(均p〈0.05);共同培养前IL-12和TNF.仅分别为(750.3±89.2)pg/L和TNF—α(282.5±15.3)ng/L,共同培养后分别为(480.6±79.5)pg/L和(192.6±22.3)ng/L,差异均有统计学意义(均P〈0.05);吲哚-2,3-双加氧酶(IDO)表达量增高50%。共同培养后的DC可抑制CD4+T细胞活化和幼稚T细胞向Th1细胞极化。结论脂肪干细胞(ADSCs)可能产生免疫力的负调节以及诱导免疫耐受,这对于移植或自身免疫性疾病来说无疑是提供了-个很有前途的有效方法。
