Pluripotent Stem Cells

This application note demonstrates the benefits of PBS Biotech’s PBS-Mini Vertical-Wheel® Bioreactor within a scalable workflow developed with Bio-Techne for hiPSC expansion and differentiation into functional pancreatic islet-like clusters. The bioreactor supported robust aggregate culture while maintaining  more than 95% pluripotency during hiPSC expansion and supporting progression through key stages of pancreatic differentiation. Combined with Bio-Techne’s GMP-grade reagents and analytical solutions, the workflow generated beta cell-containing, functional islet-like clusters that…

This webinar examines scalable suspension culture of PSC-derived organoids using PBS Biotech Vertical-Wheel bioreactors. PBS Applications Engineer, Hannah Worden, explains how low-shear, homogeneous mixing and consistent geometry support organoid process development and scale-up. Case studies cover liver, pancreatic islet, and cerebellar organoids, including aggregate-size control, differentiation, functional markers, and improved organization under dynamic culture. With the audience, we address agitation, seeding density, media formulation, perfusion-based medium exchange, sampling, and…

This poster, presented at ISSCR Kyoto 2026, demonstrates a scalable strategy for iPSC manufacturing using Vertical-Wheel Bioreactors, addressing expansion, process development, cell banking, and differentiation. Linear scale-up from PBS-0.1 through PBS-80 produced 200 billion iPSCs at a 50 L working volume while maintaining pluripotency and normal karyotype. High-density work cell banks were developed through 3D adaptation and retained differentiation potential toward cardiomyocytes and pancreatic progenitors. MiniPRO further served as a controlled scale-down model, demonstrating growth…

This presentation, presented at ISSCR Kyoto 2026 explores how Vertical-Wheel Bioreactors can reduce development and manufacturing risk for PSC therapies by providing a scalable platform from process development through commercial production. It highlights global clinical trials supported by Vertical-Wheel technology, predictive scale-down with MiniPRO, controlled hydrodynamics, automation, and linear scale-up through PBS-80. Data demonstrate consistent PSC growth across scales, culminating in greater than 200 billion cells from a 50 L batch while maintaining pluripotency, illustrating a…

This guide collects and summarizes process parameters from successful experiments performed in Vertical-Wheel® bioreactors, across a variety of cell types including pluripotent stem cells, mesenchymal stem/stromal cells, exosomes and extracellular vesicles, organoids, and immune cells. Find the publication or resource most relevant to your own experiment to help with your process development.

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…
