There's a human liver sitting in a lab dish in Madison, Wis. Also a heart, a brain and every bone in the human body--even though the contents of the dish are a few cells too small to be seen without a microscope. But these are stem cells, the most immature human cells ever discovered, taken from embryos before they had decided upon their career path in the body. If scientists could only figure out how to give them just the right kick in just the right direction, each could become a liver, a heart, a brain...
...cells to grow a new thumb after he lost part of his in an accident. A teenager born without half of his chest wall is growing a new cage of bone and cartilage within his chest cavity. Scientists announced last month that bladders, grown from bladder cells in a lab, have been implanted in dogs and are working. Meanwhile, patches of skin, the first "tissue-engineered" organ to be approved by the U.S. Food and Drug Administration, are healing sores and skin ulcers on hundreds of patients across...
...what Charles Vacanti, an anesthesiologist and director of the Center for Tissue Engineering, has been doing at the University of Massachusetts Medical Center in Worcester. When that machinist lopped off the top of his thumb, Vacanti took some of the victim's bone cells, grew them in the lab and then injected them into a piece of coral fashioned into the shape of the missing digit. "Coral's got lots of interconnected channels for the bone cells to grow in," says Vacanti. It also degrades as bone replaces it. The patch was implanted back on the thumb a few months...
...Auger bends a sheet of muscle cells around a plastic tube and reinforces it with an outer layer of stiffer cells. Then he removes the tube and seeds the inside with lining cells, which soon grow together. The vessels have worked well in animal tests, and in the lab have withstood blood pressure 20 times normal...
