Title
(EN) COLLAGEN IV BIOINKS
(FR) BIOENCRES DE COLLAGÈNE IV
Abstract
(EN) The present invention relates to compositions suitable for the delivery of agents to biological targets such as tissues and cells and/or capable of promoting the growth and/or proliferation of cells, and methods for the production thereof. Specifically, a printable collagen bioink comprising type IV collagen is used to produce crosslinked collagen gels comprising mammalian cells, such as endothelial or epithelial cells, for corneal regeneration.
(FR) La présente invention concerne des compositions appropriées pour l'administration d'agents à des cibles biologiques telles que des tissus et des cellules et/ou aptes à favoriser la croissance et/ou la prolifération de cellules, ainsi que des procédés pour leur production. Spécifiquement, une bioencre de collagène imprimable comprenant du collagène de type IV est utilisée pour produire des gels de collagène réticulés comprenant des cellules de mammifères, telles que des cellules endothéliales ou épithéliales, pour la régénération cornéenne.
