  • Composition comprising cryopreservation medium and stem cells obtained by slow-freezing
    Patent number: 9938495
    Abstract: Cryopreserved stem cells with high cell viability after thawing were obtained by slow freezing using a DMSO-free cryopreservation medium. Stem cells and/or progenitor cells thereof are contacted with a DMSO-free cryopreservation medium, comprising between 4 v/v % and 25 v/v % of propylene glycol and between 1.0 w % and 10 w % of a sugar; and are subsequently subject to a slow-freezing process. Optionally, the cryopreservation medium may comprise serum albumin and/or hyaluronic acid.
    Type: Grant

  • CRYOPRESERVATION TOOLS AND METHODS
    Publication number: 20150175955
    Abstract: Provided herein are methods for the cryopreservation of stem cells and/or progenitor cells, comprising the steps of (a) contacting stem cells and/or progenitor cells with a cryopreservation medium, said cryopreservation medium comprising between 4 v/v % and 25 v/v % of propylene glycol and between 1.0 w % and 10 w % of a sugar; and (b) slow-freezing said cells, thereby obtaining a frozen composition comprising said cells and said cryopreservation medium.
