Embryonic stem cell
Embryonic stem cells (ESCs)
are stem cells derived from
the undifferentiated inner
mass cells of a human
embryo. Embryonic stem cells
are pluripotent, meaning
they are able to grow (i.e.
differentiate) into all

Somatic cell
A somatic cell is generally
taken to mean any cell
forming the body of an
organism. Somatic cells, by
definition, are not germline
cells. In mammals, germline
cells are the sperm and ova
(also known as "gametes")

Stem cell treatments
Medical researchers believe
that stem cell treatments
have the potential to change
the face of human disease
and alleviate suffering. A
number of current stem cell
treatments already exists,
although they are not

Natural killer cell
Natural killer cells (also
known as NK cells, K cells,
and killer cells) are a type
of lymphocyte (a white blood
cell) and a component of
innate immune system. NK
cells play a major role in
the host-rejection of both
