| Outline of Final Research Achievements |
In this study, we developed a novel (1) DMSO-free cryopreservation solution, (2) culture device for cryopreservation, and (3) freezing system. (1) In order to safely freeze cells, it is necessary to solve the problems such as the cytotoxicity of DMSO, the antigenicity change of animal-derived materials and the possibility of contamination with pathogens. We found an optimal composition of cryopreservation solution without DMSO and serum for human cells. (2) 3D culture device TASCL was used to create a large amount of human tissue-derived stem cell constructs having a uniform size. In addition, we successfully determined a vitrified freezing condition based on the effective composition of the freezing solution. (3) In order to control cell freezing, we succeeded in developing a freezing system with a stirling engine and in optimizing freezing conditions. Consequently, a cryopreservation system of cell tissue construct for regeneration and transplantation medical care was established.
