| 摘要 |
A method for expansion of stem cells in vitro is disclosed, whereby the stem cells are continuously or intermittently exposed to a micro-current and/or electromagnetic field of constant or alternating polarity during the expansion. Particular advantages of said invention arise from the fact that, during the in vitro cultivation, the stem cells may undergo a large number of dividing cycles without a differentiation in the stem cells occurring. Furthermore, no stoma cells are required during the cultivation. The invention further relates to the stem cells produced by the above method and the use thereof for the production of a medicament, in particular for the treatment of HIV. |
