摘要
人白血病细胞HL-60在体外经NIH3T3-IFN-α ̄+细胞培养上清作用后或与该细胞共育后其生长受到显著抑制,细胞形态出现空泡,核固缩等现象。给裸鼠皮下接种HL60细胞(1×10 ̄7/只),当皮下肿瘤结节长至5mm时,给荷瘤小鼠腹腔内埋植1×10 ̄7NIH3T3-IFN-α ̄+细胞或腹腔注射阿霉素,结果发现,其皮下肿瘤结节的生长受到非常显著的抑制,特别是当NIH3T3-IFN-α ̄+细胞与阿霉素联合应用时,肿瘤生长抑制作用最明显。表明成纤维细胞介导的人IFN-α5基因疗法对人白血病有一定的治疗效果,当与适当化疗药物联合应用时疗效更佳。
ecause hIFN-αis
very effective in treating patients with leukemia,we investigated the
effect of fibroblast-mediated hlFN-αgene therapy on the human
leukemia-bearing nude mice. Thegrowth of human HL-60 leukemia cells
were inhibited significantly after HL-60 cells were incu-bated with
the NIH3T3-IFN-α ̄+ cells or their ctilture stipernatants.The HL-60
cells were inocu-lated sc into nLide mice, and then the NIH3T3- IFN-
α ̄+cells were implaiited ip iiito the leukemi-a-bearing mice or Dox
was also injected ip into the leukemia-bearing mice, The results
demonstrated that the in vivo growth of the leukemia cells was
inhibited obviously,and the better ther-apeutic effect could be
achived when NIH3T3-IFN-α ̄+cells were used in combination with
Dox。suggesting that the fibroblast mediated human IFN-α gene
therapy could be used to treat humanleukemia effectively and the
therapeutic effect would be better when it is used with
chemothera-py。
