New research suggests that killing so-called zombie cells helps older women grow new bone. ... to test a zombie cell-killer treatment in humans. And the fact that it worked at all is promising ...
For example, phosphatidylserine is an "eat-me" signal that, when exposed on the surface of a cell, triggers phagocytes (i.e. cells that eat other cells) to eat that cell. Phosphatidylserine is normally found on the inside of healthy cells, but can become exposed on the surface of dying, activated or stressed cells.
The body removes most of them. But others linger like zombies. They aren't dead. But as the Mayo Clinic's Nathan LeBrasseur puts it, they can harm nearby cells like moldy fruit corrupting a fruit ...

Phagocytosis (from Ancient Greek φαγεῖν (phagein) 'to eat' and κύτος (kytos) 'cell') is the process by which a cell uses its plasma membrane to engulf a large particle (≥ 0.5 μm), giving rise to an internal compartment called the phagosome. It is one type of endocytosis. A cell that performs phagocytosis is called a phagocyte.
From 2006 through 2009 in Japan there were 119 incidents involving 183 people but only seven people died. [65] Only a few cases have been reported in the United States, and outbreaks in countries outside the Indo-Pacific area are rare. In Haiti, tetrodotoxin was thought to have been used in voodoo preparations, in so-called zombie poisons ...

Embryonic stem cells and germ cells have also been described as immortal. [8] [9] Immortal cell lines of cancer cells can be created by induction of oncogenes or loss of tumor suppressor genes. One way to induce immortality is through viral-mediated induction of the large T-antigen, [10] commonly introduced through simian virus 40 (SV-40). [11]
