Advancing the preservation of cellular therapy products.

Cell therapies are typically collected in one location, processed in a second location, and then administered in a third location. The ability to preserve the cells is critical to their clinical application. It improves patient access to therapies by increasing the genetic diversity of cells available. In addition, the ability to preserve cells improves the "manufacturability" of a cell therapy product by permitting the cells to be stored until the patient is ready for administration of the therapy, permitting inventory control of products, and improving management of staffing at cell therapy facilities. Finally, the ability to preserve cell therapies improves the safety of cell therapy products by extending the shelf life of a product and permitting completion of safety and quality control testing before release of the product for use. The support of the National Blood Foundation has been critical to our work on improving the quality of frozen and thawed cell therapy products through the development of a microfluidic device to remove dimethlysulfoxide (DMSO). We are also involved in research to replace DMSO with other agents that are less toxic to cells and patients. Finally, the need to advance the preservation of cell therapies was a driving force behind the development of the Biopreservation Core Resource (http://www.biocor.net), a national resource in biopreservation. New interest in translation of cell therapies from the bench to the patient's bedside has the potential to drive the transformation of preservation science, technology, and practice.
