New method makes embryo-safe stem cells
| Quote: |
The new method works by taking an embryo at a very early stage of development and removing a single cell, which can be coaxed into spawning an embryonic stem cell line. With only one cell removed, the rest of the embryo retains its full potential for development.

The debate continues.
Stem-cell advance whets debate
HOPES RAISED FOR `ETHICAL' SOLUTION

White House officials released a statement in response to Advanced Cell Technology's announcement that said, ``It is encouraging to see scientists making serious efforts to move away from research that involves the destruction of embryos.'' But it added, ``Any use of human embryos for research purposes raises serious ethical concerns. This technique does not resolve all those concerns.''
...
Although the technique hadn't produced human embryonic stem cells when the report was written, the panel noted that it seemed safe in theory because at least 1,000 babies had been born without noticeable harm after having had a cell removed for genetic testing. Nonetheless, it said children born through such a procedure would have to be studied for years to be sure the technique poses no health risk.
In addition, the panel concluded, ``Subjecting otherwise healthy embryos to biopsy procedures in order to derive stem cells seems ethically troubling.''
That echoed the objections from some critics who said even if Advanced Cell Technology's approach seems safe for embryos, it shouldn't be tried.
...
Christopher Thomas Scott, who directs Stanford University's Center for Biomedical Ethics Program in Stem Cells and Society, said more studies also are needed to prove the procedure makes stem cells comparable to those produced in current methods.
No matter how promising the procedure turns out to be for making stem cells, it still might not pass muster with the Bush administration. That's because Bush's policy bars federal financing for any stem-cell lines derived from a human embryo after Aug. 9, 2001, regardless of the method.
Given the politics surrounding stem cells, however, it's hard to predict how the federal government will react to the Advanced Cell Technology procedure, said Larry Goldstein, a stem-cell expert at the University of California-San Diego School of Medicine.
