Wound healing disorders are a serious health problem today, affecting millions of people worldwide. One promising solution in the fight against these disorders is the use of natural biomaterials that can support different stages of the regeneration process. My project aims to develop a new class of keratin dressings enriched with a factor stimulating macrophage colonies. Such colonies will be capable of modulating impaired immune processes observed in chronic wounds, thereby accelerating their healing, writes Dr. Mateusz Rybka from the Department of Experimental Physiology and Pathophysiology at the MUW.
