Abstract

The continuous development of simple and practical cell cryopreservation methods is of great importance to a variety of sectors, especially when considering the efficient short- and long-term storage of cells and their transportation. Although the overall success of such methods has been increased in recent years, there is still need for a unified platform that is highly suitable for efficient cryogenic storage of cells in addition to their easy-to-manage retrieval. Here, a paper-based cell cryopreservation method as an alternative to conventional cryopreservation methods is presented. The method is space-saving, cost-effective, simple and easy to manage, and requires no additional fine-tuning to conventional freezing and thawing procedures to yield comparable recovery of viable cells. It is shown that treating papers with fibronectin solution enhances the release of viable cells post thawing as compared to untreated paper platforms. Additionally, upon release, the remaining cells within the paper lead to the formation and growth of spheroid-like structures. Moreover, it is demonstrated that the developed method works with paper-based 3D cultures, where preformed 3D cultures can be efficiently cryopreserved.
