abstract = {In this work a system of culture techniques was developed
for the ex vivo expansion of hematopoietic cells, which is
of major importance in cancer therapy. For stroma dependent
cocultivation, the fixed bed reactor and the 1 mL
miniaturized loop reactor allow the cultivation for clinical
and screening purposes, respectively. Here the cells are
immobilized on macroporous carriers . For a suspension
culture a reactor was developed that has a working volume
between 40 and 550 mL. An integrated filtration allows a
continuous cultivation up to densities of 1 . 107C/mL.
Finally, a small scale spinner vessel of 10 mL suspension
offers the possibility of a screening in suspended culture.
Additionally, some relevant parameters for the cultivation
of hematopoietic progenitor cells were investigated. It was
shown, that the materials the cultivation systems are made
of have an influence on the cultivation, but in technical
systems it is to small to be relevant . An optimal
osmolality of the culture was found at 0,31-0,32 Osmol/kg .
Besides the progenitor cells, T-lymphocytes were cultivated
as an example of a more differentiated cell type . After the
successful cultivation in the new suspension reactor system,
a standard 20L stirred vessel was used to obtain a
clinically relevant final cell number of 2,9 - 101° cells.
The new suspension systems was used also in a clinical study
phase I/II for cancer therapy of children. Cells obtained
from the reactor were transfused to a patient, who showed no
negative side effects from the therapy},
