Abstract:
The Renca-bearing mice were treated by combined fibroblast-mediated IL-2 and G-CSF gene therapy. The survival periods of Renca-bearing mice were prolonged markedly and 75% of Renca-bearing mice were cured. The spleens of Renca-bearing mice treated by fibroblast-mediated G-CSF gene therapy were larger than the spleens of other mice. Histologic analysis of tumor showed that there were a number of infiltrating eosinophils. The NK, LAK and CTL activity induced from the splenocytes of the tumor-bearing mice increased siginificantly when the mice were treated by fibroblast-mediated IL-2 gene therapy and the cytotoxicity of macrophages also increased. The results demonstrated that the and - tumor responses might be induced more significantly by combined fibroblast-mediated IL-2 and G-CSF gene therapy and better antitumor effect may be achieved.
