Scientists at Columbia Engineering have developed a bioactive, injectable healing gel derived from yogurt. By harnessing extracellular vesicles (EVs) from milk, the team developed a soft material that mimics living tissue and promotes natural regeneration. This novel gel doesn’t just deliver therapeutic molecules; the EVs help build the structure of the gel itself. In mouse models, it boosted blood vessel formation and tissue repair—without added chemicals. The research hints at a future where food-derived biotechnology plays a powerful role in healing the body.
