Increased [Ca2+]cyt activates plasma membrane anion efflux channels, and these two effects combine to depolarize the membrane. Membrane depolarization closes voltage‐sensitive K+ in channels but opens K+ out channels.

Unlike pluripotent stem cells, adult or multipotent stem cells in culture not only have a restricted array of cell types that they can create, but they also have a finite number of generations for self-renewal.

When a multipotent stem cell divides asymmetrically, its maturing daughter cell often goes through a transition stage as a progenitor or transit-amplifying cell, as is seen in the formation of blood cells, sperm, and neurons.
