Abstract
A method of cultivating cells of animal and human tissues includes the steps of introducing the cells into a nutrient solution in which they tend to settle, and maintaining the cells in the solution in a suspended state so as to prevent their settling by introducing an oxygen-containing gas into the solution. An apparatus for carrying out the method includes a container for a nutrient solution, an arrangement for introducing the oxygen-containing gas into the container, and a guide arrangement in the container and operative for guiding the nutrient solution so that the latter performs a circulatory movement in the container when the oxygen-containing gas is introduced into the latter. The guide arrangement may be formed as a tubular member, as a substantially flat partition wall, or as an inner wall of a circumferentially complete tubular container.
