PBS-0.5 Vertical-Wheel® PSC Perfusion Vessels
This brochure introduces the PBS-0.5 Vertical-Wheel® PSC Perfusion Vessel, an integrated perfusion solution for pluripotent stem cell aggregate cultures and other large-particle processes. Continuous medium exchange through an integrated retention filter can support aggregate homogeneity, reduce manual handling, and enable downstream differentiation workflows. Comparative data show tighter aggregate-size distributions and smaller average aggregate diameters with perfusion than settlement-based medium exchange. The brochure also covers scalability, equipment compatibility, ordering information, and available bioprocess development support.
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…
