title: Effects of chitin/chitosan and their oligomers/monomers on release of type I collagenase from fibroblasts.
abstract: The effects of chitin/chitosan and their oligomers/monomers on the release of type I collagenase (MMP-1) from fibroblasts were evaluated using adult (adFB) and neonatal human fibroblasts (neFB) by a immunological assay. Release of MMP-1 from adFB increased significantly or tended to increase for all samples, while there was no significant change in MMP-1 levels with neFB. Because the oligomers and monomers of chitin and chitosan influenced MMP-1 activity, it was suggested that the elevated MMP-1 activity would continue until biodegradation of chitin and chitosan was complete.
