Moving from the thumb to other hand parts, Charles' brother Joseph Vacanti, a transplant surgeon and tissue-engineering pioneer in his own right, has grown human-shaped fingers on the back of a mouse, demonstrating that different cell types can grow together. He and colleagues at Boston's Massachusetts General...
VEINS AND ARTERIES. Blood vessels present a special challenge: they must be strong yet flexible enough to expand and contract with each heartbeat. Joseph Vacanti's group has grown a tube of sheep-muscle cells around a polymer, added closely packed lining cells to the inside and stitched it into...
LIVERS AND BLADDERS. Anthony Atala, a surgeon who makes bladders at Boston's Children's Hospital, has taken muscle cells from the outside of dog bladders and lining cells from the inside and grown them in his lab. The cells, fed the proper growth-prompting chemicals, happily go forth and...
Although Jones is handling only 70 breast-implant cases, his opinion is expected to exert considerable influence on other judges who are grappling with similar suits brought by thousands of women. One reason: Jones took the unusual step of appointing four independent experts to assess the purported link between the...
