Development of Scalable, Versatile, and Cost-Effective Processes for iPSC-Derived Cell Therapy Manufacturing via Linear Scale-Up and High-Density Cell Banking Approaches
This poster presents a three-dimensional process for linear scale-up of human induced pluripotent stem cell expansion from 0.1 to 80 L in Vertical-Wheel® Bioreactors. Cultures maintained growth, aggregate sphericity, pluripotency, karyotype, and functional pluripotency across scales. Serial aggregate culture and scalable harvest, concentration, and cryopreservation generated high-density working cell banks that retained viability, growth, genomic stability, and differentiation competence after thaw. The banks supported shortened endocrine, islet-like, and cardiomyocyte workflows through 2D-to-3D or direct-thaw expansion before differentiation.
This publication reports a fully suspended process for expansion and six-stage differentiation of human induced pluripotent stem cells into stem cell-derived islets in 0.1 L and 0.5 L Vertical-Wheel® Bioreactors. A fivefold increase in vessel volume produced a twelvefold increase in islet-equivalent yield without compromising islet structure. The 27-day process generated endocrine populations expressing ?-, ?-, and ?-cell markers with glucose-responsive insulin secretion and transcriptomic characteristics approaching adult islets. The study also evaluated donor-derived iPSC lines, cellular…
This protocol provides step-by-step guidance for forming and expanding pluripotent stem cell aggregates in PBS-MINI Vertical-Wheel® bioreactors. The workflow begins with thawing and adherent seed-train culture in T-flasks, followed by transfer to three-dimensional suspension culture in 0.1 L or 0.5 L vessels. Instructions cover inoculation, medium exchange, sampling, morphology assessment, metabolite and pH analysis, cell counting, viability testing, and harvest in the PBS-Mini bioreactor. The document presents recommended starting parameters for seeding density, working volume, agitation…
This protocol provides detailed instructions for expanding mesenchymal stem cells on microcarriers using PBS-Mini bioreactors with Vertical-Wheel technology. The document covers the complete workflow from recovery of cryopreserved MSCs and expansion in adherent culture through inoculation, suspension culture, sampling, medium exchange, and harvest in three-dimensional bioreactor systems the PBS-Mini bioreactor. Recommended process parameters are based on internal optimization studies using multiple MSC lines and media formulations. Guidance is provided for microcarrier preparation, cell…
