Function method for enhancing immune cells and blood cells by Tgp preservation solution containing a microgravity load

PROBLEM TO BE SOLVED: To provide a method for further enhancing functions of various cells, such as the NO production ability of NK cells.SOLUTION: According to the present invention, a method for enhancing a cellular function comprises at least a step of, after embedding cells in an aqueous solution in a low-temperature sol state, the aqueous solution containing at least a hydrogel-forming polymer showing a thermo-reversible sol-gel transition in which the aqueous solution is in a sol state at low temperatures and is in a gel state at high temperatures, bringing the aqueous solution containing the cells into a high-temperature gel state and culturing the cells under microgravity.SELECTED DRAWING: None
