Application of Mesenchymal Stem Cells (MSCs) as a cell therapy product requires extensive cell expansion as the fraction of MSCs isolated from tissue is extremely small compared to the large number of clinically administered cells. Regarding biopharmaceutical production, the manufacturing process is crucial as it determines product quality and properties. In this work, a microcarrier-based expansion process was developed, optimized and successfully scaled up to the bioreactor level. Detailed analysis of expanded cells revealed a significant effect of the expansion method on MSC characteristics and function. Furthermore, to avoid the cell-damaging treatment associated with traditional enzymatic or mechanical detachment methods, MSC cultivation on newly developed thermoresponsive surfaces was evaluated.
