摘要： The invention concerns cross-linked dextran polymer Dx bearing anionic groups wherein the at least divalent radical L(-)i is covalently bound to the dextran polymer backbone with i -W- radicals, wherein,
- L(-) i is a linear or branched polyether
- i is the valence of L and the number of -W- radicals bound to the dextran polymer and is an integer comprised from 2 to 8 (2 ≤ i ≤ 8),
- -W- is a radical comprising at least a radical alkyl linear or branched and optionally comprising heteroatoms such as oxygen, nitrogen or sulfur, aromatic cycles, polyether derivatives and that does not comprise two or more alpha aminoacid residues in particular linked by peptidic bond(s).

It also concerns the dextran polymers before the crosslinking reaction and the process to synthetize a cross-linked dextran polymer according to the invention, into the form of a hydrogel.
It also concerns a hydrogel comprising the crosslinked dextran polymer of the invention and/or a hydrogel that further comprises biological cells.
It also concerns therapeutic use of the hydrogel according to the invention for treating a disorder or disease in a mammal wherein the disorder or disease is due to lack or malfunction of endocrine function of pancreas organ and an implant comprising the hydrogel according to the invention.

摘要： The present invention is intended to provide a hydrogel that utilizes the naturally occurring substance pectin to exhibit an equivalent or greater effect. Specifically, the present application is intended to provide a hydrogel or a patch which is stable, has strong adhesive strength, is advantageous for drug delivery, can be used for sustained treatment, has extremely low cytotoxicity, and is unlikely to induce an immune response, and thus can be used on various body parts, in particular the oral cavity. In addition, the present invention is intended to provide a hydrogel patch which employs a freezing method prior to crosslinking, and thus exhibits superior adhesion to patches employing a post-crosslinking freezing method.
