CA 2395456

The present invention relates to a cell growth substrate polymer that is obtainable by polymerizing a polymerizable component comprising at least one hydrophilic monomer or macromer which is devoid of a sulfo group, at least one sulfo-group-containing monomer, and optionally a crosslinker in a weight ratio as defined in the claims. The polymers of the invention are useful, for example, as substrates for the attachment and growth of mammalian cells and tissue and in particular as materials for the manufacture of biomedical devices and prostheses, including implanted devices.

La présente invention concerne un polymère substrat de croissance cellulaire qui peut être obtenu par polymérisation d'un élément polymérisable comprenant au moins un monomère ou macromère hydrophile dépourvu de groupe sulfo, au moins un monomère à groupe sulfo, et éventuellement un agent de réticulation selon un pourcentage pondéral défini dans les revendications. Les polymères de l'invention peuvent être utilisés par exemple en tant que substrats pour la fixation et la croissance de cellules et tissus mammifères et en particulier en tant que matériaux servant à la réalisation de dispositifs biomédicaux et prothèses, y compris de dispositifs à implanter.
