Abstract[English]
Biocompatible macroporous microcarriers, including microcarrier beads, microspheres, capsules, microsponges, hydrogels and other matrix forms, appropriate for use in a shaking flask or bioreactor to culture cells are described herein that can be used to create an edible structure for consumption or research investigation. Biocompatible, macroporous microcarriers can be dissolved or remain in the final product. Biocompatible macroporous microcarriers are formed by saccharides that are cross-linked via chemical induction with agitated cryo-gelation. Cross-linked macroporous, saccharide-microcarriers are coupled to adherence factors that enable cell binding. Finally, the cells are attached to the microcarrier for proliferation.[French]
Microsupports macroporeux biocompatibles, comprenant des billes de microsupport, des microsphères, des micro-éponges, des hydrogels et d'autres formes de matrice, appropriés pour être utilisés dans un flacon à agitation ou un bioréacteur pour cultiver des cellules qui peuvent être utilisés pour créer une structure comestible pour la consommation ou la recherche. Les microsupports macroporeux biocompatibles peuvent être dissous ou rester dans le produit final. Les microsupports macroporeux biocompatibles sont formés par des saccharides réticulés par induction chimique avec cryogélation par agitation. Les microporteurs macroporeux réticulés à base de saccharides sont couplés à des facteurs d'adhérence pour permettre la fixation des cellules. Enfin, les cellules sont fixées au microsupport pour la prolifération.
