Significant strides are being made toward growing replacement organs in the lab, and in substantially repairing badly damaged ones in situ including injecting muscle and pacemaker cardiomyocites grown from embryonic — and potentially even adult — stem cells. Growing Replacement Organs Growing entire organs in the lab requires scaffolding for the cells to grow on […]

Human arteries have been grown from scratch in the lab. Of practical benefit in its own right, this development further opens the door to the production of lab-grown whole organs. A 3-D printer is being used to build replacement arm bones for patients, right on the spot in the operating room. Superstrong conductive nanowires might […]
