Columbia Scientists Create Healing Gel from Yogurt That Mimics Human Tissue

Swift Summary:

• Researchers from Columbia Engineering have developed an injectable hydrogel platform using extracellular vesicles (EVs) derived from yogurt for applications in tissue engineering and regenerative medicine.
• EVs, naturally secreted by cells, enable refined cellular communication but are challenging to use in biomaterials due to yield constraints. The study leveraged milk-based EVs to overcome these barriers.
• Yogurt-derived EVs act as both structural elements and bioactive cargo in the injectable hydrogel, mimicking living tissue mechanics while promoting healing and regeneration without chemical additives.
• The hydrogel demonstrated biocompatibility and angiogenic activity within one week in immunocompetent mice, triggering new blood vessel growth and creating an anti-inflammatory immune environment conducive to tissue repair.
• Researchers validated that the approach is modular, incorporating EVs from various sources including mammalian cells and bacteria for broader regenerative applications.
• Key collaboration involved teams from Columbia university and the University of Padova who combined expertise in nanomaterials, hydrogels, and agricultural EV sourcing.
