Cryopreservation by vitrification is an effective approach for long-term preservation of biosystems, but effective vitrification often requires high concentrations of cryoprotective agent (CPA), which can be toxic. The investigators described a joule heating–based platform technology for rapid rewarming of biosystems, which allows the use of low concentrations of CPA. They demonstrated the success of this platform in cryopreservation of three model systems: adherent cells, Drosophila melanogaster embryos, and rat kidney slices with low CPA concentrations. This work provides a general solution to cryopreserve a broad spectrum of cells, tissues, organs, and organisms. Supported by ORIP (R21OD028758), NIDDK, NHLBI, and NIGMS.
