Delivery of Dermatan Sulfate from Polyelectrolyte Complex-Containing Alginate Composite Microspheres for Tissue Regeneration

Dermatan sulfate (DS) is a glycosaminoglycan (GAG) with a great potential as a new therapeutic agent in tissue engineering. The aim of the present study was to investigate the formation of polyelectrolyte complexes (PECs) between chitosan and dermatan sulfate (CS/DS) and delivery of DS from PEC-containing alginate/chitosan/dermatan sulfate (Alg/CS/DS) microspheres for application in tissue regeneration. The CS/DS complexes were initially formed...
