Аннотация:Grafted amides with the degree of modifi cation reaching 9% were prepared by the reaction of chitosan
with unsaturated higher fatty acids in an acidifi ed aqueous medium in the presence of a mixture of N-ethyl-N′-
(dimethylaminopropyl)carbodiimide hydrochloride with N-hydroxysuccinimide. The products are insoluble in
aqueous solutions of monobasic acids but swell in them to form hydrogels; the maximal degree of swelling is
1442%. The hydrogels show good biocompatibility and adhesion of multipotent stromal cells of bone marrow,
which makes them promising for designing cell carrier scaff olds.
