abstract = {The ex vivo expansion of hematopoietic cells is an
important technique for many medical applications. The
cultivation concept in this study was the ex vivo simulation
of the human bone marrow by co-culture of hematopoietic and
stromal cells in a fixed-bed bioreactor . Thereby the cells
are immobilized on macroporous collagen microcarriers. A
miniaturized loop-reactor was established for screening
purposes. For the full supply with primary CD34<sup>+</sup>-
cells a cord blood bank was built up. In preliminary
investigations two stromal cellines were characterized and
the harvest of immobilized cells established by enzymatic
lysis of the carriers. The relevant parameters for the
co-culture were optimized in the miniaturized loop- reactor.
In this system the mononuclear cells (MNC) were expanded up
to 454 fold, the colony-forming-cells (CFC) up to 26 fold
and the cobblestone-area-forming cells (CAFC) up to 18 fold.
In this system the SCm-mouse repopulating cells (SRC) were
maintained in contrast to a parallel cultivation in a
suspension system. This demonstrates the positive effect of
the stromal based, immobilized culture compared to the
suspension culture of this cells. Based on the optimization
in the screening system the hematopoietic cells were
successfully expanded in the fixed-bed bioreactor. The
co-culture with the stromal cellline SVSl and the cytokines
IL-3, TPO, SCF and FL led to the best results. In this
system the MNC were expanded maximal 103 fold, the CFU-GM
114 fold and the CAFC 15 fold. These data correspond the
medical yardstick demonstrating the clinical relevance of
the results presented in this study.},
