Abstract[English]
The present invention provides, among other things, compositions and methods for protecting cell therapy products from cryoinjury, in particular immune cells (e.g., NK cell products), during cryopreservation. The cryoformulation compositions and methods of the present invention reduce cryoinjury during cryopreserving process, thereby increasing cell therapy product recovery, viability and function after cryopreservation.[French]
La présente invention concerne, entre autres, des compositions et des procédés pour protéger des produits de thérapie cellulaire contre une cryolésion, en particulier des cellules immunitaires (par exemple, des produits de cellules NK), pendant la cryoconservation. Les compositions de cryoformulation et les procédés de la présente invention réduisent la cryolésion pendant le processus de cryoconservation, ce qui permet d'augmenter la récupération, la viabilité et la fonction du produit de thérapie cellulaire après cryoconservation.
