Abstract
(EN)
A cryopreservative composition includes a sugar component with a total concentration of sugar components in the composition of 300 mM or less; a sugar alcohol component, with a total concentration of sugar alcohol components in the composition of 2 M or less; and at least one of a polymer component and albumin, with the proviso that the composition includes less than a cryopreservative amount of dimethyl sulfoxide (DMSO). A method of cry opreserving a cell includes adding a cell to the cryopreservative composition; freezing the composition; storing the frozen composition; thawing the composition; removing the cell from the thawed composition; and culturing the cell under conditions effective for the cell to remain viable. The freezing may include cooling at a rate of 0.1 °C/min to 5 °C/min. The method may be performed without a washing step after thawing.
(FR)
Une composition de cryoconservation comprend un composant de sucre, avec une concentration totale de composants de sucre dans la composition de 300 mM ou moins; un composant d'alcool de sucre, avec une concentration totale de composants d'alcool de sucre dans la composition de 2 M ou moins; et un composant polymère et/ou de l'albumine, à condition que la composition comprenne moins d'une quantité de cryoconservation de diméthylsulfoxyde (DMSO). Un procédé de cryoconservation d'une cellule comprend l'ajout d'une cellule à la composition de cryoconservation; la congélation de la composition; le stockage de la composition congelée; la décongélation de la composition; le retrait de la cellule de la composition décongelée; et la culture de la cellule dans des conditions efficaces pour que la cellule reste viable. La congélation peut comprendre le refroidissement à une vitesse de 0,1 °C/min à 5 °C/min Le procédé peut être exécuté sans étape de lavage après la décongélation.
