...government finally made available the first 13 stem-cell lines that researchers can study with federal funds. Researchers had been awaiting the announcement since March 9, when President Obama signed an Executive Order lifting the ban that former President George W. Bush had placed on government support of human-embryonic-stem-cell research. The previous Administration had restricted federally funded studies to only the dozen or so stem-cell lines that had been created before Aug. 9, 2001. The new policy allows scientists to experiment with any existing stem-cell line, regardless of when it was created, as long...
Already, the Federal Government has given out 31 grants totaling about $21 million for research involving the larger pool of human embryonic stem cells. But the recipients of that money have been waiting to use it since September, when the NIH, charged with establishing and applying the stem-cell vetting criteria, began reviewing potentially eligible cells. In addition to the 13 lines approved on Wednesday, another 96 lines are waiting for the green light, 20 of which may get it by Friday...
...lines are added to the government registry. A larger pool of available stem cells is a more accurate reflection not only of the diversity of the population but also of the variety of forms that treatable diseases can take. That translates into more opportunities for researchers to study basic human development and disease development, screen new drugs for their effectiveness against disease and create entirely new therapies. The ultimate goal is to use stem cells, which can morph into any of the body's hundreds of different cell types, to cure disease by repairing or even replacing damaged or defective...
Some experts worry that the stringent vetting and documentation processes may place an undue burden on labs that have painstakingly created human-embryonic-stem-cell lines using their own hard-earned private funds. (Researchers are still prohibited from using federal money to create new stem-cell lines because of a congressional ban on harming or destroying embryos.) According to some estimates, as many as 780 such lines may exist worldwide, but not all labs may be willing to subject themselves to the scrutiny and administrative hassle of registering their lines with the NIH. Even among the handful of stem-cell...
...despite the relatively slow start for American stem-cell research, Rockefeller's Brivanlou is hopeful that the NIH approvals mark the beginning of a new era in our understanding of human development. "I consider it a shame that at the beginning of the 21st century, we know more about how development works in the worm, the fruit fly and the mouse than we know about our own development. And it's not because of scientific limitations or technological limitations," he says. "It would be nice if someday people are allowed to ask basic questions simply about where we come from...
