Webinar: Stem Cell Advancement Beyond Embryonic Cell Use

In cell biology, 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.

In contrast to pluripotent stemcells, many progenitor cells are multipotent, i.e. they are capable of differentiating into a limited number of tissue types.
