Abstract:
ObjectiveTo search for a new method of anti-tumor immunity,using mutated tumor cells by spaceflight.MethodsTumor cells were carried in the Shenzhou 4 and the recoverable satellite No.18.After 7 days and 18 days spaceflight respectively,the effects of spaceflight were investigated primarily.Results2382 and 1 strains of mutated tumor cells from the airship No.4 and the recoverable satellite No.18 had been obtained respectively. Comparing with the control group, the growth rate of mutated cells decreased, moreover, the secretion of cytokines also changed.ConclusionSpaceflight may affect physiological characteristics of tumor cells, and that, there was a negative correlation between the ratio of surviving cells and carrying time.
