...think the word cowboys comes to mind," says Robert Stillman, medical director at Shady Grove Fertility Center in Rockville, Md., the country's largest fertility clinic...
...This requirement was originally set up to empower patients, who can now assess their chances of getting pregnant on the basis of a particular clinic's success rate. But the reporting system has evolved into being a way to monitor a clinic's number of multiple births, which are more dangerous - and more costly - for mother and baby...
...welcome as that change will be, it may be less urgent now - owing primarily to the work of scientists like Melton. While embryonic stem cells remain the gold standard for any treatments that find their way into the clinic, newer techniques using the next-generation stem cells may soon surpass the older ones...
...field encompasses far more than just embryonic and adult stem cells; it has expanded into the broader field of regenerative medicine, and Melton's lab at Harvard is at the vanguard, bringing the newest type of stem cells, which do not rely on embryos at all, closer to the clinic, where patients will actually benefit. Last summer, Melton stunned the scientific community with yet another twist, finding a way to generate new populations of cells by reprogramming one type of fully mature cell so it simply became another, bypassing stem cells altogether. "If I were in high school...
...sperm. Eggs begin their development process with the full complement of 46, but shed half of them, tucking them into a small genetic bundle known as a polar body, which mirrors the chromosomes of the egg. Investigators at the U.K.'s CARE Fertility clinic, under the direction of Dr. Simon Fischel, harvested nine eggs from a woman who had undergone 13 failed cycles of IVF implantation and, in addition, suffered two miscarriages and an ectopic pregnancy. Using a laser scalpel, they extracted the polar bodies from the eggs and analyzed them. Two of the nine proved defect-free, and both...
