In September 1998 scientists at Johns Hopkins University made a second discovery. They isolated human primordial <!g>germ cells (<!g>hEG) from aborted fetuses at five to eight weeks. These cells are also <!g>pluripotent, though it appears that they may not be immortal. To date they hEG cells have not shown quite the promise of the <!g>hES cells; but further research is being pursued. Our ethical analysis in this article will not take up issues related to human <!g>embryonic germ cells.
