Abstract:
The effects of human interferons (HuIFN) on the human osteosarcoma cells were examined. HuIFN-alpha, -beta and -gamma enhanced dose-dependently the cell growth. There was no difference in the degree of the enhancement of the cell growth among HuIFN-alpha, -beta and -gamma. The higher the cell density was, the lower the degree of the enhancement of the cell growth. When HuIFN-gamma was neutralized with anti-HuIFN-gamma, the enhancement of cell growth was not found.
