Abstract: Mesenchymal stem cells (MSCs) are able to differentiate in vivo and in vitro giving rise to different cell types including osteoblasts, adipocytes, chondrocytes and neuronal cells, providing a valuable source for treatment of degenerative and age-associated diseases. Im-provement of protocols and procedures for human MSCs cryopreservation will contribute significantly to the development of cell replacement therapies. We developed an alternative cryopreservation solutions for stem cell cryopreservation. Most cryoprotectants need to be removed from the cells by washing after thawing, a procedure that can lead to a loss of precious stem cells. Additionally, the procedure is time and cost-consuming. In our study we used a combination of transfusable and non-toxic substances such as hydroxyethylstarch, sorbitol and dextran replacing DMSO and FCS. We found that a cryosolution containing 5% HES, 0.3M sorbitol and 5% dextran provide successful protection for human umbilical cord derived mesenchymal stem cells. These MSC retain a high viability and show multilineage differentiation.
