Abstract:

Human cellular therapies are used extensively in clinical studies and as drug discovery tools. Current culture methods involve
cumbersome multilayer flatbed culture and roller bottle systems. Several groups previously demonstrated an expansion
paradigm that uses a scalable, single use, stirred tank bioreactor for cell expansion. A bioreactor system enables direct monitoring
for the specific cell characteristics at any point during the expansion, thus assuring product quality and consistency. In addition, a
bioreactor provides ease of use in handling and lower medium volume requirements. Cells cultured in bioreactors were evaluated to
assess a variety of markers that confirm identity and purity. No differences were observed in protein markers. Finally, we evaluated
concentration technologies and found that good recovery of viable cells is achievable. In this work, we verified that the cells expanded
in the single use stirred tank bioreactor and subsequently harvested were identical to those grown in traditional systems.
