Methods for Long-Term Storage of Murine Bone Marrow-Derived Mesenchymal Stem Cells.

This chapter is based on a simplified method to validate the current preservation procedure of mesenchymal stem cells (MSCs). Currently, there are various media available for freezing and thus preserving the MSCs, making it hard to decide which agent will be apt for cellular requirements. The study describes the effect of two different compositions of freezing media used in regular cell culture experiments, on the morphology, proliferation, and doubling rate of MSCs. Commonly used agents for the cryopreservation of MSCs include DMSO (Dimethyl Sulfoxide) and FBS (Fetal Bovine Serum) and DMEM (Dulbecco's Modified Eagle Medium). To ascertain that the currently used agents do not lead to major changes in the MSC morphology and proliferation, the cells are frozen using the above-mentioned agents in different groups and then their effects analyzed. Thus, the chapter helps to decide what reagents can suit the MSCs, hence minimizing the laboratory to laboratory variability of their characteristics.
