Abstract excerpt
Human embryonic stem cells (hESCs) are unique in that they can proliferate indefinitely in culture in an undifferentiated state as well as differentiate into any somatic cells. Undifferentiated hESCs do not appear to undergo senescence and remain nontransformed over multiple passages.
