The role of biopreservation in cell and gene therapy bioprocessing
Cell and gene-based therapies represent a novel therapeutic modality that has the potential to provide a treatment option for a range of medical conditions. There are, however, numerous processing and manufacturing challenges that must be addressed before such therapies are considered commercially and clinically viable. A significant challenge associated with the manufacture of such therapies is ensuring cell quality and the product’s critical quality attributes are retained throughout the entire bioprocess. Biopreservation is an important aspect of cell and gene-based therapy bioprocessing, which enables the development of cell banks. It increases process flexibility by providing a shelf-life to the product, enables the storage of intermediates and provides breakpoints within the process. In this article, we summarize the advances and challenges associated with biopreservation of cell and gene therapies.
