METHOD FOR MODIFYING POLYSACCHARIDES BY GRAFTING POLYETHERAMINES, POLYSACCHARIDES THUS MODIFIED AND PREPARATIONS COMPRISING SAME AND HAVING HEAT-SENSITIVE RHEOLOGICAL PROPERTIES

摘要

A modification of natural or synthetic polysaccharides by grafting polyetheramines, and the use of modified polysaccharides in the form of a hydrogel as a medium for cell culture. These hydrogel preparations may have heat-sensitive rheological properties that are interesting for their intracorporeal use in human and veterinary medicine, for cell culture and transport of biological samples.
