EG Cells Embryonic germ cells .
These cells are found in a specific part of the embryo/fetus called the
gonadal ridge, and normally develop into mature gametes .

Primordial Germline Cells The source of embryonic germ cells .
In normal development, these are the cells that give rise to eggs or

Somatic Cells Cells from the body
that compose the tissues, organs, and parts of that individual other than the
germ (sex) cells.
15. Stem Cell Topic: Current Status of Human Stem Cell Research
Totipotent stem cells are cells that can
give rise to a fully functional organism as well as to every cell type of the
stem cells are capable of giving rise to virtually any tissue type, but not to

the potential of
human stem cells from these various sources.
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

those involving the use of cells obtained from
embryos (ES cells), or from deliberately aborted fetuses (EG cells). The fact that much basic research needs to
be done in the area of human embryonic development suggests that both ES and EG

divided. They reproduced themselves. Because these cells are as yet
undifferentiated--that is, they are pluripotent and able to make any part of a
human body--they are

the discovery of human stem cells (precursor
cells that can give rise to multiple tissue types), including embryonic stem
(ES) cells, embryonic germ (EG) cells, and adult stem cells. Recently,
techniques have been developed for the in vitro

Initially and naively, we could breathe a sigh of relief. If
