Abstract： 目的:探讨大鼠树突状细胞(dendritic cells, DCs)融合瘤苗在骨肉瘤免疫治疗中的应用. 方法:用大鼠骨肉瘤细胞系UMR-106建立大鼠骨肉瘤动物模型,应用重组大鼠rGM-CSF, rIL-4和nrhTNF-α培养大鼠骨髓前体细胞获得大量DCs,经标抗大鼠OX62 mAb免疫磁珠分离纯化后的DCs经形态学观察、表型检测、功能学实验鉴定,然后将细胞系UMR-106与大鼠树突状细胞融合作为瘤苗应用于荷瘤大鼠,观察其抑制肿瘤生长和肺转移的效果. 结果:在治疗6 wk时治疗组和对照组相比,瘤重明显减小(P<0.01);肺转移发生率降低(P<0.01). 结论:大鼠骨肉瘤细胞系UMR-106与树突状细胞的融合瘤苗可望在骨肉瘤的治疗中发挥作用.
