...tissue. The mouse cells provide the human ones with nutrients and growth factors crucial to their survival and proliferation. The problem: under FDA rules, mouse-fed stem cells given to treat human patients would be considered a "xenotransplant," or tissue from another species. Although hundreds of patients have received liver and fetal cells from pigs without any sign of foreign infection, the agency could halt a stem-cell procedure if it felt the human patient was at risk of getting an animal virus. The news sparked renewed calls for the President to loosen his policy and allow further harvesting from...
Langer's approach to the design of biomaterials has paved the way for the emergence of the new field of tissue engineering. Working closely with Harvard's Joseph Vacanti, Langer is using tailor-made polymers to build tiny scaffolds that can then be seeded with skin, cartilage, liver or other cells. The idea is to provide a temporary structure that cells can colonize and upon which they can eventually grow into a functioning organ--at which point the scaffold dissolves away. Langer foresees the day when scientists will be able to grow a new liver or pancreas for patients waiting...
...roar and turned to see the SUV lurch backward, directly at him and a line of people waiting to get into the club. When the car came to a stop, 16 people were pinned against the building's front wall. Conlon had sustained injuries to his leg, shoulder and liver. Someone opened the driver's door and Grubman "fell out of the car," said a witness. She fled in a friend's car. By the time patrol cars got to the friend's house, so had her lawyer. With her attorney running blocker, police could not even ascertain if Grubman...
Those are some mighty big ifs, of course. After all, the man was on the verge of dying before last week's operation--and still could die at any moment. His liver and kidneys are in pretty bad shape. He could suffer any number of surgical complications, from internal bleeding to infection to strokes...
...What can stem cells do for us? We don?t know, exactly. We do know, however, that because stem cells are undifferentiated, (they aren?t committed to becoming a liver cell, say, or a blood cell), scientists may be able to prompt them into becoming whatever type of cell is needed. The cells may also be able to replace damaged or sick cells in a patient with an injury or degenerative disease...
