THREE-DIMENSIONAL STRUCTURE INCLUDING PARTICLES OF CHITOSAN HYDROGEL |
| abstract |
The present invention relates to a three-dimensional structure formed of particles of physical hydrogel of chitosan or of chitosan derivative, associated with an anionic polymer, where said hydrogel particles are of average size between 10 µm and 1.5 mm. The anionic polymer is preferably hyaluronic acid or a derivative of hyaluronic acid or a complex of hyaluronic acid. This structure can be advantageously used for inoculating cells, in particular chondrocytes, for the purposes of proliferation and synthesis of an extracellular matrix. The structure is also suitable for use in cartilage repair or for use as an implant, or as a graft or as an active ingredient carrier in humans or animals. |
