WebAdult stem cells are found in a tissue or organ and can differentiate to yield the specialized cell types of that tissue or organ. Pluripotent stem cells. Early mammalian embryos at the blastocyst stage contain two types of cells – cells of the inner cell mass, and cells of the trophectoderm. The trophectodermal cells contribute to the placenta. WebMost adult neural stem cells are maintained in a state of reversible cell cycle arrest, also called quiescence. Quiescent neural stem cells present a low rate of metabolic activity and a high sensitivity to their local signaling environment, and they can be activated by diverse physiological stim- uli.
