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