Abstract
Abstract: "Hyaluronic acid (HA), a non-sulfated glycosaminoglycan (GAG), is a significant component of the epidermal extracellular matrix (ECM). It plays multiple roles in the inflammatory response, cell adhesion, migration, proliferation, differentiation, angiogenesis, and tissue regeneration. Due to its inherent characteristics, including non-immunoreactivity, exceptional biocompatibility, biodegradability, native biofunctionality, hydrophilicity, and non-immunoreactivity, HA has found applications in the production of wound dressings. HA's synergistic role in enhancing deeper penetration into chronic wounds and its biofunctional properties in the healing process have been harnessed. HA-based wound dressings, often incorporating biomolecules or drugs to improve the dressing's biochemical performance during wound healing, have been developed. In this review, we explore the current state of knowledge regarding hydrogels based on HA, focusing on their biofunctional properties and delivery mechanisms. We present the latest developments in the research and development of HA-based hydrogels for the treatment of skin wounds."
