A product of a freshwater single-celled green algae called Euglena gracilis may enhance skin regeneration to speed up wound healing, according to new research published in Advanced Materials Interfaces.

Investigators developed a system based on microvesicles that bud from the cell surface of Euglena gracilis and contain β-glucan, a carbohydrate with immunoregulatory activity, regeneration ability, and antioxidant properties.

In laboratory experiments, these microvesicles promoted the proliferation and migration of skin cells, increasing both collagen synthesis and the expression of proliferation-associated proteins. A wound healing test also generated promising results.
