The routine therapeutic and industrial applications of human pluripotent stem cells (hPSCs) require their constant mass supply by robust, efficient, and economically viable bioprocesses. Our protocol describes the fully controlled expansion of hPSCs in stirred tank bioreactors (STBRs) enabling cell densities of 35 3 106 cells/mL while reducing culture medium consumption by 75%. This is achieved by in silico process modeling and computable upscaling. We provide a detailed blueprint for systematic process development of hPSCs and their progenies.
