Researchers have created an injectable gel able to generate new blood vessels that could reduce the number of amputations due to peripheral vascular disease.
Developed by a team from MIT, the new therapy involves first extracting the fibrous extracellular matrix from the skeletal muscle of pigs. That matrix is then embedded in a gel and injected into the affected area, where it helps to repair both the vascular system and muscle tissue. In tests on diabetic mice, the gel was able to restore up to 85 percent of normal blood flow to limbs with diseased vessels.
