๐ง Injected Gel Turns Stroke-Damaged Brain Into a Self-Repair Zone โ in Mice
Duke University biomedical engineers developed MAPS โ microporous annealed particle scaffolds โ a hydrogel injected into the cavity a stroke leaves behind. It recruits the body's own immune cells to grow new blood vessels and rewire neural tissue, and after 8 weeks treated mice matched healthy controls on forelimb coordination tests. Published in Cell Biomaterials, this is still preclinical, but it's a genuinely new approach to an injury the brain almost never fixes on its own. Could a scaffold like this one day help human stroke survivors regain movement?
