Biomedical engineers at Duke University have created an injectable biomaterial that may help the brain recover from damage left behind by an ischemic stroke. In experiments with mice, the material transformed the cavity created by lost brain tissue into a more favorable environment for healing.

The treatment recruited the body's own immune cells, encouraged the formation of new blood vessels, supported changes in neural tissue, and improved motor function in the animals.

The findings were published in Cell Biomaterials.

The Challenge of Repairing Brain Tissue After Stroke

Millions of people experience ischemic strokes each year. These strokes occur when a blood clot blocks blood flow to part of the brain.
