Summary:
Scientists at Columbia Engineering have developed an injectable hydrogel made from yogurt-derived extracellular vesicles (EVs) that could revolutionize regenerative medicine. These EVs serve both as healing agents and as structural components, eliminating the need for added chemicals. The innovation leverages everyday dairy products like yogurt to create a biocompatible material that mimics natural tissue and enhances healing.
Researchers from Columbia Engineering have established a framework for the design of bioactive injectable hydrogels formulated with extracellular vesicles (EVs) for tissue engineering and regenerative medicine applications.
