Human Embryonic Germ Cells
Embryonic germ cells are
derived from primordial germline cells in early fetal tissue during a narrow
window of development. Unlike embryonic
stem cells , animal experiments on embryonic germ cells have

Stem Cells : What Are They?
Many
types of stem cells exist in the human body. All have the capacity to replicate,
to self-renew; and they have the capacity to differentiate in order to produce
specific body parts such as muscle cells,
