1. A method for proliferating stem cells, comprising:
- introducing medium, microcarriers and stem cells into a container, cultivating the stem cells on microcarriers in said container, wherein the cells do not lose their stem cell characteristics after having initiated the culturing, and removing the cells on the microcarriers from the container, wherein after having initiated the culturing the medium in the container is moved and not moved in an alternating manner, wherein the medium is moved between 10 and 100 minutes and is not moved between 10 and 60 minutes in an alternating manner.

Abstract
The invention relates to a process for cultivating undifferentiated stem cells in suspension and in particular to a method for cultivating stem cells on microcarriers in vessels. The method enables stem cells to be cultivated in a scalable process for the first time, without losing their pluripotentiality. Different types of vessels are suitable for cultivation, such as e.g. spinners and bioreactors. The option of precisely setting the cultivation conditions in said vessels aids the process of obtaining a pluripotentiality of the stem cells. the inventive method also permits large yields of stem cells of an unvarying quality to be produced.
