MIT Scientists Develop Injectable Mini Livers to Support Failing Organs

Researchers at MIT have developed injectable 'mini livers,' small engineered tissue grafts designed to support failing livers without surgery. These 'satellite livers' combine liver cells with hydrogel microspheres to perform key liver functions, potentially aiding patients with severe liver disease and those awaiting transplants. Early tests in mice showed the grafts remained functional for months, offering a possible alternative to organ transplantation amid donor shortages and surgical risks.
