Don’t you worry about your broken heart!
Scientists at Tel Aviv University have taken a major step forward in regenerative medicine by creating a living, beating human heart using only a patient’s own fat cells. The team reprogrammed these fat cells into stem cells and then used advanced 3D printing techniques to form a small heart complete with chambers, blood vessels, and cardiac tissue that can contract on its own.
While the heart is not yet large or strong enough for transplantation, researchers see it as a crucial proof of concept. Because the organ is built entirely from the patient’s own cells, it could one day greatly reduce rejection risks and the need for donor organs. This breakthrough points toward a future where personalized, lab grown organs help address global transplant shortages.
