一种利用热可逆超分子凝胶低温冻存胰岛细胞的方法

Islets transplantation is an important method for the treatment of diabetes, but it is difficult to preserve enough health islets for transplantation. Cryopreservation is the most common method to preserve cells for a long time. The gelator self-assembled to supramolecular gel cryopreservation system in the islets suspension. Cell damage can be reduced significant since the three-dimensional network structure can confine the ice crystal growth. In addition, because the supramolecular gel is thermal reversible, it can be easy removed in the thawing process. The thawed islets activities and functions are similar to fresh islets.
