MIT Engineers Create Injectable Mini Livers to Support Failing Organs

MIT researchers have engineered a new therapy that delivers miniature liver constructs directly into patients with severe liver failure. The system injects clusters of liver cells, tiny hydrogel spheres, and supportive stromal cells, forming a pocket of functional tissue. Once inside the body, the construct integrates with the host’s bloodstream, allowing the transplanted cells to perform essential metabolic tasks. The approach bypasses the need for a full organ transplant and could reduce waiting times and complications associated with donor organs. Early laboratory tests show the mini livers maintain key liver functions, suggesting a promising alternative for patients whose native livers can no longer sustain life.
