Harnessing the immense therapeutic and research potential of stem cells requires extensive quality control to ensure the identity, quality, and safety of the cell. Stem cells of different origin and their capability to differentiate towards a specific phenotype as well as tissue engineered constructs are dependent of all kinds of bioprocesses including cultivation media, biomechanical conditions and purification techniques. All topics dealing with the optimization and analysis of processes leading to defined in vitro cultivated cell lines and engineered tissues - with a special focus on bioreactors - will be discussed in this session. This event has CPD accreditation.
