3. Stem Cell Topic: Moral Issues Surrounding the Sources of Stem Cells
the Sources of Stem Cells
At present, there are three possible sources of stem cells: adult stem
cells derived from pediatric or adult donors; embryo germ cell stem cells (EG
cells ) derived from aborted fetuses; and embryonic stem

Embryonic stem cells (ES cells ) derived from early embryos and embryonic
germ cells (EG cells) have particular promise for a wide range of therapeutic
applications because they are capable of giving rise to virtually any cell
type.
