Courtesy of David Hill, ART Reproductive Center Inc.Two separated blastomeres subjected to FISH analysis to check the chromosomes. In early October, preimplantation genetic diagnosis (PGD) made headlines when a Colorado couple used assisted reproductive technology (ART) to have a baby named Adam, whose umbilical cord stem cells could cure his six-year-old sister Molly's Fanconi anemia.1 When Adam Nash was a ball of blastomere cells, researchers at the Reproductive Genetics Institute at Illinois

POSITIVE SIDE EFFECT Proposed legislation designed to ban genetic discrimination may boost participation in clinical trials, says Kathy L. Hudson, assistant director for policy coordination at the National Human Genome Research Institute. Vice President Al Gore issued guidelines for genetic discrimination legislation in a report entitled "Genetic Information and the Workplace" January 20 at the National Academy of Sciences. The legislation, if enacted, would bar employers from using genetic mak

File photo It is a sobering time for US stem cell researchers. Just days after a national election set the stage for the possible criminalization of embryonic stem cell research, a popular television program portrayed such cells incubating in patients in coma, ready to be used to treat a wealthy man's Parkinson disease. A video presented at the American Society for Human Genetics annual meeting in Baltimore a month earlier, however, told a very different story--this one real. The video showed
