Title
(EN) GROWTH CONTROL FOR CELLS ENCAPSULATED WITHIN BIOARTIFICIAL ORGANS
(FR) REGULATION DE LA CROISSANCE POUR DES CELLULES ENCAPSULEES DANS DES ORGANES BIOARTIFICIELS
Abstract
(EN)
This invention relates to methods and compositions of controlling cell distribution within a bioartificial organ by exposing the cells to a treatment that inhibits cell proliferation, promotes cell differentiation, or affects cell attachment to a growth surface within the bioartificial organ. Such treatments include (1) genetically manipulating cells, (2) exposing the cells to a proliferation-inhibiting compound or a differentiation-inducing compound or removing the cells from exposure to a proliferation-stimulating compound or a differentiation-inhibing compound; exposing the cells to irradiation, and (3) modifying a growth surface of the BAO with ECM molecules, molecules affecting cell proliferation or adhesion, or an inert scaffold, or a combination thereof. These treatments may be used in combination.
(FR)
Cette invention se rapporte à des procédés et à des compositions qui permettent de contrôler la distribution des cellules dans un organe bioartificiel, en exposant les cellules à un traitement qui inhibe la prolifération cellulaire, qui favorise la différenciation cellulaire ou qui affecte la fixation des cellules à une surface de croissance à l'intérieur de l'organe bioartificiel. Ces traitements consistent: (1) à manipuler génétiquement les cellules, (2) à exposer les cellules à un composé inhibiteur de prolifération ou à un composé inducteur de différenciation ou à retirer les cellules de leur exposition à un composé stimulateur de prolifération ou à un composé inhibiteur de différenciation, à exposer lesdites cellules à un rayonnement, et (3) à modifier une surface de croissance de l'organe bioartificiel au moyen de molécules de matrice extra-cellulaire, au moyen de molécules affectant la prolifération cellulaire ou l'adhésion cellulaire, ou au moyen d'un support inerte, ou d'une combinaison de ceux-ci. Ces traitements peuvent être utilisés combinés les uns aux autres.
