(SciTechDaily) – A stroke can leave behind more than damaged brain cells. In severe cases, it creates an empty cavity where living tissue once carried signals, supplied blood, and controlled movement.
Duke University researchers are now testing an injectable material designed to turn that biological void into a place where repair can begin. In mice, the treatment drew immune cells into the stroke cavity and helped organize them into a coordinated healing response.
New blood vessels spread through the injured area, nerve fibers became more abundant, and the animals regained motor abilities that approached those of healthy mice. CONTINUE
