Scaling Up Stem Cells: Moving from Laboratory to Commercial Production with a Single-Use Multiplate Bioreactor

Cell-based products are becoming increasingly important as potential biotherapies. Cell therapy is predicted to have a huge impact on the healthcare sector over the coming decades. Stem cells, in particular, are investigated as potential treatments for a diverse range of applications (such as heart disease and metabolic and inflammatory disorders) in which they might be used to restore lost biological functions.

Expansion and Characterization of Mesenchymal Stem Cells on Pall SoloHill® Microcarriers

Mesenchymal stem cells (MSCs) are self-renewing cells that differentiate into several terminally differentiated cell types. These cells have been isolated from multiple sources such as bone marrow, adipose tissue, peripheral blood, and other adult tissues(1–6). The interest in these cells is that they hold the potential to cure disease and are being pursued in clinical trials. Three emerging fields of interest for stem cells are cell therapy, regenerative medicine and screening of candidate drugs. In many cases, poor correlation between…

Strategies for Microcarrier Culture Optimization

The process of delivering an allogeneic stem-cell therapy to patients requires isolation and expansion of rare tissue-specific stem cells, which are subsequently delivered to individual patients for treatment. One type of cell used for such therapies is commonly known as human mesenchymal stem cells (hMSCs). They have been isolated from a number of tissues: e.g., bone marrow, heart, brain, placenta, and umbilical cord. And they have been shown to be immune-privileged in that hMSCs elicit no graft-versus-host (GvH) response such…

Designing the Most Cost-Effective Manufacturing Strategy for Allogeneic Cell-Based Therapies

Rapid progress is occurring in the field of stem cell therapy research, and increasing numbers of products will begin reaching the market in the near future. But new cell therapy treatments must fit into a competitive and highly regulated healthcare environment. Succeeding in that environment requires alignment between a company’s business model and its manufacturing strategy. Read the full text of this article in the PDF (Login required).

Production of Viral Vectors Using the iCELLis® Fixed-Bed Bioreactor System: Beyond Mesenchymal Stem Cells — Gene-Modified Cell Therapy, Gene Therapy, and Exosomes

In the past few years, the resurgence of cell-based immunotherapies — and, by extension, gene therapies — has accelerated as products move rapidly from academic research laboratories into commercial development. A successful clinical trial by St. Jude Children’s Research and the University College London of a gene therapy for hemophilia B was a seminal translational event (1), as was the licensing of the University of Pennsylvania’s gene-modified chimeric antigen receptor T-cell technology (CAR-T) for leukemia by Novartis (2). CAR-T cells…

Single-Use Bioreactors and Microcarriers: Scalable Technology for Cell-Based Therapies

Cell-based therapies hold promise for treating many acute and chronic diseases (1). Optimism surrounding that therapeutic potential has driven the initiation of multiple clinical trials in pursuit of such treatments. Procedures for preparing these therapeutic agents begin with selective isolation of cells from desired tissues. That is followed by ex vivo expansion of cells of desired phenotype and functionality. Once expanded to acceptable levels, cells are stored to preserve their viability during transportation to treatment facilities. The final step in…

Ask the Experts: Core Technologies Expand Opportunities for Cell Therapy Manufacturing

Pall Life Sciences has long been known for its expertise in processing and filtration equipment for the biopharmaceutical industry. In recent years, the company has broadened its offerings in upstream manufacturing by expanding its core capabilities in the single-use, bioreactor, and microcarrier arenas, with unique and innovative technologies for cultivation of cells to be used as therapies.

Positioning Tools, Technologies, and Talents for Cell Therapies: An Interview with Harvey Brandwein

On 12 March 2015, BPI publisher Brian Caine and editor in chief Anne Montgomery spoke with Harvey Brandwein, Pall’s vice president of business development, at the company’s Port Washington, NY, facility. Pall’s director of marketing for cell therapies, Alain Fairbank, also provided her thoughts on the evolution of tools and technologies for this market sector. Knowing that this interview would become one of the concluding chapters in Pall’s special issue with BPI, we reviewed a number of topics covered earlier,…

Choosing Between Single-Use and Multiuse Technologies: A BPI Theater Roundtable at Interphex 2015

On Tuesday, 21 April 2015, Eric S. Langer (managing partner at BioPlan Associates) chaired a midday roundtable titled, “Deciding on Single-Use vs. Stainless Steel Bioprocessing Strategy: What Do CMOs Know That Biopharmas Don’t?” Langer brought together these industry experts to discuss choosing between stainless steel and single-use technologies (SUTs) for different applications: William Hartzel (director of strategic execution at Catalent Pharma Solutions) Steven Perry (vice president of technical operations at Cook Pharmica) Joanna Pezzini (bioprocess engineer at MedImmune) Daniel Vellom…
