Description générale

Chondroitin, a glucosaminoglycan (GAG), is a polysaccharide chain of alternating units of N-acetylgalactosamine (GalNAc) and glucuronic acid (GlcA) that can be sulfated on the either or both GalNAc and GlcA units. Chondroitin and its sulfates are frequently attached to proteins to form proteoglycans.

Application

Chondroitin sulfate, a glucosaminoglycan (GAG) polysaccharide chain of alternating units of N-acetylgalactosamine (GalNAc) and glucuronic acid (GlcA), is used in a wide variety of areas of research including bioengineering. Chondroitin sulfate may be used as a biomaterial copolymer or surface derivatization reagent in the development of drug delivery vehicles, tissue engineering devices and bioscaffolds. Chondroitin sulfate may be used for the development of biocompatible structures such as hydrogels, sponges, biofilms, microspheres and micelles.

Actions biochimiques/physiologiques

As a large, negatively charged, hydrophilic molecule that is too inflexible to fold into a compact globular structure, chondroitin sulfate molecules form porous hydrated gels, providing mechanical support to tissue and allowing rapid diffusion of water-soluble molecules and migration of cells.

Composants

Chondroitin is an acidic mucopolysaccharide found in cartilage, skin, cornea, and umbilical cord. It is composed of alternating N-acetylgalactosamine, D-glucuronic acid, and sulfate residues in equimolar quantities that can be sulfated on either of its subunits. Sulfation can occur at the 6 and/or 4-position of the galactosamine moiety, with potential for any individual disaccharide unit to be 6-sulfated, 4-sulfated, 4,6-disulfated, or unsulfated.

Nonviral polycation-based gene carriers (polyplexes) have attracted attention as safe and efficient gene delivery systems. Polyplex micelles comprised of poly(ethyleneglycol)-block-poly{N'-[N-(2-aminoethyl)-2-aminoethyl]aspartamide} (PEG-PAsp(DET)) and plasmid DNA (pDNA) have shown high transfection efficiency with low toxicity due to the pH-sensitive protonation behavior of

The ability of residual antigens on decellularized tissue to elicit the immune response upon implantation motivates development of a more rigorous antigen removal (AR) process for xenogeneic scaffold generation. Antigen removal strategies promoting solubilization of hydrophilic proteins (predominantly cytoplasmic) enhance
