A Fishy Way To Grow New Skin

Kerecis has found a fishy way to battle the growing problem of chronic wounds and faltering healing factors

Six hours north of Reykjavik, along a narrow road tracing windswept fjords, is the Icelandic town of Isafjordur, home of 3,000 people and the midnight sun. On a blustery May afternoon, snow still fills the couloirs that loom over the docks, where the Pall Palsson, a 583-ton trawler, has just returned from a three-day trip. Below the rust-spotted deck, neat boxes are packed with freshly caught fish and ice. “If you take all the skins from that trawler,” says Fertram Sigurjonsson, the chairman and chief executive officer of Kerecis Ltd., gesturing over the catch, “we would be able to treat one in five wounds in the world.”

Iceland has a long history of working with fish leather. “My grandfather’s first shoes were the skin of a catfish,” Sigurjonsson says. Instead of kilometers, Icelanders used to mark distance in wornout fish shoes. Sigurjonsson and his small company have spent the past nine years applying this tradition to the treatment of chronic wounds, those that take longer than a month to heal.

The materials in fish skin, particularly omega-3 fatty acids, yield natural anti- inflammatory effects that speed healing. When placed on wounds, the product, made from dried and processed fish skin, works as an extracellular matrix, a group of proteins and starches that plays a crucial role in recovery. In a healthy person, a matrix surrounds cells and binds them to tissue, generating the growth of new epidermis. But in chronic wounds, this natural structure fails to form. So like a garden trellis, the fish skin provides the body’s own cells a structure to grow around so they can form healthy tissue, gradually becoming incorporated into the closing wound.
