The Genome News Network provides an informative article on the current state of the art in tissue engineering for regenerative medicine. There is some impressive work being done at the forefront of the field: "This is not imaginary science anymore," says William Haseltine, CEO of Human Genome Sciences. "Functional tissues made from cells and biomaterials are being implanted in humans." Teams of scientists have grown and successfully implanted entire organs in the lab, using biodegradable scaffolds and the patient's own cells. This is impressive medical technology: waiting for transplants may soon be a thing of the past.
