Development of Large-Scale Bulk Freezing Systems

The biopharmaceutical industry is under pressure to generate value for shareholders and find innovative therapies while driving down development and manufacturing costs. As the industry considers more flexible and scalable production solutions for patients, new therapies will continue to be developed faster than ever before. These products will need to rely on robust and reliable manufacturing solutions. To deliver on that challenge, streamlining manufacturing processes will be necessary so that many lots of drug substances can be manufactured, stored, and/or…

A Novel 3D Culture System for High-Throughput Hepatoxicity Screening

Cells grown as three-dimensional (3D) spheroids are thought to more closely mimic in vivo physiology in terms of morphology, structural complexity, and phenotype. Being more physiologically relevant, 3D cultures can be highly predictive for compound profiling and evaluating cytotoxicity, a critical step in evaluating chemotherapeutic drug candidates. Unfortunately, evaluation of drug cytotoxicity traditionally has relied on the use of two-dimensional (2D) cell culture monolayers. When grown in monolayers, cells are not exposed to soluble gradients, are forced into an apical-basal…

The Effect of Albumin on Viability in Stem Cell Therapy

Stem cell therapies are some of the most cutting-edge and sophisticated therapeutic developments. They offer an attractive alternative approach to more widely used treatments for conditions such as multiple sclerosis, metabolic diseases, cardiovascular disease, liver disease, and cancer. But developers still face challenges, some of which can be addressed by the use of recombinant human albumin. As a long-established ingredient of cell culture media, albumin is well recognized for its ability to facilitate growth of many cell types. The industry is expanding its use of high-quality, fully recombinant, current good manufacturing practice…

Optimizing Cryopreservation for Therapeutic Cells

    Biopreservation suppresses degradation and enables postpreservation recovery of structure, viability, and function. Although there are several biopreservation techniques (indicated in “Biopreservation Methods” box), most laboratories use either standard cryopreservation protocols (the far majority) or vitrification (much more limited in broad systems application) when freezing cells for research and clinical applications. Isopropanol freezing containers such as the Mr. Frosty device from Nalgene Labware have made cryopreservation easier in many applications, and controlled-rate freezers allow users to program and manipulate…
