Hyaluronic acid which is known to have many skin and ageing related benefits has found itself at the midst of one more use – wound healing.
According to a team of scientists at the Kaunas University of Technology, Lithuania, hyaluronic acid has anti-inflammatory properties and stimulates tissue regeneration and this could be put to good use in wound dressings. The team is developing a new generation sponge-like wound dressings with hyaluronic acid. Antimicrobial, antioxidant, anti-inflammatory wound dressings stimulate tissue regeneration and can be especially efficient in treating deep wounds that are difficult to heal.
For deep wound to heal successfully, tissue regeneration is extremely important. Development of new generation wound dressings, which assist this process, is one of biggest challenges in tissue engineering. Kaunas University of Technology (KTU) researchers are developing sponge-like wound dressings based on hyaluronic acid, which is a well-researched polymer stimulating tissue regeneration and used in ophthalmology, bone regeneration and for other medical and cosmetic purposes.

Sponge-like wound dressings created at KTU have net structure, which is essential in developing wound dressings for tissue regeneration. Although biopolymers are often chosen for this purpose as they are compatible with biological systems, sponge-like wound dressings are mostly being made from alginate or collagen.
At the moment, KTU researchers have built hyaluronic acid scaffolds, which can be used for tissue regeneration. Collaborating with the Lithuanian University of Health Sciences, the scientists are testing the prototype in vitro with different cells. According to researchers, the proof of concept stage research can take up a few more years.
