Abstract[English]
Disclosed are durable polysaccharide compositions comprising GAGs covalently crosslinked with a carbohydrate crosslinker, and methods of making the same. GAG hydrogels according to the present disclosure have a molecular weight of at least 1.5 MDa, crosslinked by a crosslinker forming amide bonds with the GAG backbone and an elastic modulus (G') of less than or equal to 200 Pa. Further described are methods of using the durable polysaccharide compositions for treating skin (e.g., in reparative or plastic surgery, esthetic dermatology, facial contouring, body contouring, or gingival augmentation).[French]
Sont divulgués des compositions de polysaccharide durables comprenant des GAG réticulés de manière covalente avec un agent de réticulation glucidique, et leurs procédés de fabrication. Les hydrogels GAG selon la présente divulgation présentent un poids moléculaire d'au moins 1,5 MDa, réticulé par un agent de réticulation formant des liaisons amide avec le squelette GAG et un module élastique (G') inférieur ou égal à 200 Pa. L'invention concerne en outre des procédés d'utilisation des compositions de polysaccharide durables pour le traitement de la peau (par exemple, en chirurgie réparatrice ou plastique, en dermatologie esthétique, en remodelage facial, en remodelage corporel ou en augmentation gingivale).
