  • Publication number: 20230292741
    Abstract: The present invention provides methods for cryopreserving a population of cells with improved cell viability. In some aspects, the method comprises contacting a population of cells with a peptoid polymer comprising one or more polar peptoid monomers, e.g., formulated in a cryoprotectant solution, and cooling the population of cells at a temperature of from 0° C. to about ?20° C. for a time period of at least about 3 hours to produce a population of supercooled cells. The supercooling methods of the present invention provide excellent post-thaw cell survival and recovery. In certain embodiments, the population of cells is present in a tissue or an organ that is cryopreserved by performing the supercooling methods of the present invention.

  • Publication number: 20210298290
    Abstract: The present technology relates to apparatuses and methods for preserving biological material, for example cryopreserved biological material, such as cells, tissues, and organs for storage and/or transport. Apparatuses and methods of the present technology preserve biological material at a target temperature within a range of 8° C. to ?40° C. for extended periods of time, for example at least 4 hours. The target temperature and extended period of time may be achieved with the use of cold sources such as phase change materials (PCMs) in combination with insulation materials, such as vacuum insulation panels (VIPs) and/or aerogels.
