Title (EN) HYDROGEL FOR ENDOGENOUS NEUROPROGENITOR CELL RECRUITMENT
(FR) HYDROGEL PERMETTANT LA SÉLECTION DE CELLULE PROGÉNITRICE NEUROLOGIQUE ENDOGÈNE
Abstract:
(EN) A hydrogel material for the treatment of stroke or other brain injury includes a collection of hyaluronic acid-based microgel particles comprising one or more network crosslinker components, wherein the hyaluronic acid-based microgel particles, when exposed to an endogenous annealing agent (e.g., Factor XIIIa), links the hyaluronic acid-based microgel particles together in situ to form a covalently-stabilized scaffold of microgel particles having interstitial spaces therein. The hydrogel material may be injected into a stroke cavity and was shown to promote brain tissue repair by promoting the recruitment of neural stem cells to the injured site and reducing the post-stroke inflammatory response.
(FR) L'invention concerne une matière d'hydrogel destinée au traitement d'accident vasculaire cérébral ou d'une autre lésion cérébrale, qui comprend une collection de particules de microgel à base d'acide hyaluronique comprenant un ou plusieurs éléments de réticulation de réseau, les particules de microgel à base d'acide hyaluronique, lorsqu'elles sont exposées à un agent de recuit endogène (par exemple, le Facteur XIIIa), liant les particules de microgel à base d'acide hyaluronique ensemble in situ pour former un échafaudage à stabilisation covalente de particules de microgel ayant des espaces interstitiels à l'intérieur de ce dernier. La matière d'hydrogel peut être injectée dans une cavité d'accident vasculaire cérébral. Il s'avère qu'elle favorise la réparation de tissu cérébral en favorisant la sélection de cellules souches neuronales au site de lésion et en réduisant la réponse inflammatoire post-accident vasculaire cérébral.
