Title
(EN) NEURAL TISSUE UNIT AND USE OF SUCH A UNIT FOR IMPLANTATION IN THE NERVOUS SYSTEM OF A MAMMAL
(FR) UNITÉ DE TISSU NEURAL ET UTILISATION D'UNE TELLE UNITÉ POUR L'IMPLANTATION DANS LE SYSTÈME NERVEUX D'UN MAMMIFÈRE
Abstract
(EN) The invention concerns a neural tissue unit for use thereof for implantation in the nervous system of a human or non-human mammal, wherein said neural tissue unit contains differentiated postmitotic neuronal cells, in an extracellular matrix, said unit being obtained from a cellular microcompartment comprising a hydrogel capsule surrounding the neural tissue unit, and said hydrogel capsule being at least partially eliminated before using the neural tissue unit. The invention also concerns a method for preparing such a neural tissue unit.
(FR) L'invention concerne une unité de tissu neural pour son utilisation pour une implantation dans le système nerveux d'un mammifère humain ou non humain, dans laquelle ladite unité de tissu neural contient des cellules neuronales post-mitotiques différenciées, dans une matrice extracellulaire, ladite unité étant obtenue à partir d'un microcompartiment cellulaire comprenant une capsule en hydrogel entourant l'unité de tissu neural, et ladite capsule en hydrogel étant au moins partiellement éliminée avant utilisation de l'unité de tissu neural. L'invention concerne également un procédé de préparation d'une telle unité de tissu neural.
