Zombie cells
Senescent cells were first described in 1961 by US biologists Leonard Hayflick and Paul Moorhead, who discovered that human cells in a laboratory dish will divide no more than about 50 times before either dying or entering the twilight state of cell senescence2. In the lab, it can take weeks for dividing cells to become senescent. But researchers have yet to uncover how much time this process takes in the body, how long senescent cells last and whether all cell types can become senescent.
It's so funny last night I started watching the Twighlight saga.
