...wind up my last year at Harvard, I find myself vaguely nonplussed. Have four years of nonsensical response papers and vacuous political conversations changed my essence, my marrow? I have changed boyfriends several times, that is true, but that has seemed more a function of whim than personal evolution. A cute man is increasing hard to find. When I look back on my life before Harvard, I find I was pretty much the same person, except that I did not know what country fried steak was and I did not have a newspaper column in which I lambasted other people?...
...Cord blood has several advantages over bone marrow transplants, the procedure to which it is most often compared. The first is that cord blood is collected without risk to the mother or the newborn, whereas a bone marrow donor faces surgery and general anesthesia. Cord-blood transplants also require a less perfect match in unrelated people, opening up a broader spectrum of potential donors, and recipients' bodies are less likely to reject a transplant...
...checkmark offered a lifeline. Last May, Beninati received a transplant of stem cells harvested from the blood of an infant's discarded umbilical cord at Boston's Dana Farber Institute, to help him fight a rare blood condition called myelodysplastic syndrome. After doctors couldn't find a matching bone-marrow donor, the 58-year-old New Yorker says his last hope was cord blood, a solution that would not exist without parental donors. New parents, Beninati urges, "must understand the importance this decision can mean for the public good...
...Despite the claim by the National Marrow Donor Program (NMDP) that more than 10,000 new patients each year could benefit from cord-blood stem-cell transplants, most umbilical cords currently end up as medical waste. Today, a matching donor from the national registry is found only about 25% of the time, and many patients die waiting. So far, doctors have found the most promise in cord blood for conditions such as blood cancers, leukemia and sickle-cell anemia. But last year, an ongoing study at the University of Florida showed cord-blood cells could also be effective at treating...
Researchers believe the new procedure, which begins with a partial destruction of the patient’s bone marrow using a drug, may decrease organ rejection. The bone marrow gives rise to immune cells that help the body identify invaders. If the foreign marrow produces foreign cells, the study’s authors hypothesized that the body will recognize the transplant...
