Totipotency is the ability of a single cell to divide and
produce all the differentiated cells in an organism,
including extraembryonic tissues. Totipotent cells formed
during sexual and asexual reproduction include spores and
zygotes.the definition of pluripotency has come to refer to
a stem cell that has the potential to differentiate into
any of the three germ layers: endoderm (interior stomach
lining, gastrointestinal tract, the lungs), mesoderm
(muscle, bone, blood, urogenital), or ectoderm (epidermal
tissues and nervous system). Pluripotent stem cells can
give rise to any fetal or adult cell type. However, alone
they cannot develop into a fetal or adult animal because
they lack the potential to contribute to extraembryonic
tissue, such as the placenta.
