...Keone's dream seems about to come true, thanks to a pioneering medical treatment. Exactly a year ago last week, Keone, now 13, became the first sickle-cell patient to receive a transplant of blood cells from the umbilical cord of a newborn infant. In effect, he got a new bloodmaking system. Other young sickle-cell patients have undergone transplants, but these involved bone-marrow cells and had to be matched precisely with the recipients' own blood. In Keone's case, though, his half-sister could not offer matching marrow. So his doctors decided to turn to more easily available...
...kill his bone marrow, the source of his sickled blood cells, as well as to neutralize his immune system so it would accept the new cells. These came from an anonymous donor at the New York Blood Center and were fed intravenously into Keone on Dec. 11 last year by Yeager and his colleagues at the AFLAC Cancer Center of Children's Healthcare of Atlanta (formerly Egleston Children's Hospital...
...Last week, on the first anniversary of the transplant, Yeager finally felt justified medically in pronouncing Keone cured. "The cord blood cells are now fully operational, making all healthy blood cells in Keone," he says. Equally important, there was no sign of sickle cells and no need for more transfusions. That, of course, was a coup for the doctors, who believe their widely watched experiment could benefit other severely ill sickle-cell kids who can't find matching donors for conventional transplants. Indeed, Yeager believes using umbilical cells could increase the number of successful transplants...
...cost of its predecessors, riveted the nation's attention in 1997 with its live feed from the Red Planet's surface. And three years after its arrival Mars Global Surveyor is still sending back detailed photos and important data about the water-sculpted Martian landscape, including powerful evidence, released last week, that the planet's north pole was once covered by a vast ocean. It seemed that Goldin's management mantra--"faster, better, cheaper"--was more than just a trendy sound bite...
...makes sense--if it's done right. Says Pike: "This should provide an opportunity for a midcourse correction." Some sort of correction may already be under way. Goldin has launched a new investigation to look into the Polar Lander loss, and NASA chief of space science Edward Weiler said last week the agency would rethink its ambitious schedule of sending multiple missions to Mars every 26 months through 2007. After years of tipping the other way, "better" may finally be getting the same attention as "faster" and "cheaper" in NASA's mind...
