Abstract
The function of liver tissue cells can be maintained over a long period of time by culturing the liver tissue cells on a cell culture support, which is coated with a polymer showing a change in the hydration force in the temperature range of from 0 to 80° C., within the temperature range wherein the polymer has a small hydration force, then changing the temperature of the liquid culture medium to a level at which the polymer shows a large hydration force, thus stripping off the liver tissue cells having been cultured, and transplanting the thus obtained liver tissue cells into a definite site in vivo.
