Title
(EN) METHODS OF PREPARATION OF SECRETOMES, AND USES THEREOF
(FR) PROCÉDÉS DE PRÉPARATION DE SÉCRÉTOMES ET LEURS UTILISATIONS
Abstract
(EN) Pharmaceutical compositions and methods of producing them are described. The pharmaceutical composition may include (A) a follistatin protein or a variant thereof, and (B) a fetuin A protein or a fragment or variant thereof, wherein (B) is capable of binding to TGF-β, and wherein the total amount of (A) and (B) is greater than 10% of total proteins in the composition. Methods of preparing a secretome composition may include culturing stem cells in a protein-free media comprising trehalose, harvesting supernatant from the sample and replacing the supernatant with a fresh protein-free media comprising trehalose, and combining the harvested supernatant to prepare the secretome composition.
(FR) L'invention concerne des compositions pharmaceutiques et leurs procédés de production. Une composition pharmaceutique peut comprendre (A) une protéine follistatine ou un variant de cette dernière, et (B) une protéine fétuine-A ou un fragment ou un variant de cette dernière, (B) pouvant se lier au TGF-β, et la quantité totale de (A) et de (B) étant supérieure à 10 % des protéines totales de la composition. Des procédés de préparation d'une composition à base de sécrétomes peuvent consister à cultiver des cellules souches dans un milieu exempt de protéines comprenant du tréhalose, à récolter le surnageant de l'échantillon et à remplacer le surnageant par un milieu exempt de protéines frais comprenant du tréhalose, ainsi qu'à combiner le surnageant récolté en vue de préparer la composition à base de sécrétomes.
