use of a hydrogel for the breeding of chondrocytes

摘要

The use of a hydrogel (A), formed from silanated hydroxyethyl cellulose (HEC) or silanated hydroxypropyl methyl cellulose (HPMC) and self-crosslinkable as a function of pH, is claimed for the 3-dimensional culture of chondrocytes. An independent claim is included for an ex vivo method for a complex of cells integrated into a hydrogen, as a complex for injection into a cartilage site, involving mixing chondrocytes with (A) in vivo, in a biological buffer of pH suitable for crosslinking of (A), under conditions and for a time suitable for the integration and 3-dimensional culture of the chondrocytes in (A).
