Cryopreservation and storage of culture-expanded mesenchymal stem cells (MSCs) is essential for a biobank to maintain a collection of cell lines for research and clinical use. Optimization of cryopreservation protocols and methods to minimize damage to cells during freezing and thawing is critical to ensure reliable availability of viable cells. Controlling the freezing rate and the use of appropriate cryoprotectant, as well as stable storage temperature, can minimize the negative effects on cell viability. In this chapter, protocols for cryopreserving MSCs are described.
