Biomedical engineers at Duke University have developed an injectable biomaterial that helps transform the cavity left behind after a stroke caused by a blood clot into an environment more supportive of repair. By recruiting the body’s own immune cells, the treatment promoted the growth of new blood vessels, supported neural remodeling and improved motor performance in mice. The work appears in Cell Biomaterials.
Every year, millions of people experience strokes caused by blood clots, called ischemic strokes. Immediate treatments, including clot-dissolving drugs and mechanical removal of the clot, can restore blood flow and preserve threatened brain tissue. But these treatments cannot replace tissue that has already been lost.
Large strokes can result in substantial tissue loss a...
