New research suggests that killing so-called zombie cells helps older women grow new bone. ... This research was the clinical trial to test a zombie cell-killer treatment in humans. And the fact ...
Additionally, plants do not contain phagocytic cells, which are essential in the process of breaking down and removing apoptotic bodies. [117] Whether this whole process resembles animal apoptosis closely enough to warrant using the name apoptosis (as opposed to the more general programmed cell death) is unclear. [118] [119]
Apoptosis is the programmed cell death of superfluous or potentially harmful cells in the body. It is an energy-dependent process mediated by proteolytic enzymes called caspases, which trigger cell death through the cleaving of specific proteins in the cytoplasm and nucleus. [13] The dying cells shrink and condense into apoptotic bodies.
Overview of signal transduction pathways involved in apoptosis. Cell death is the event of a biological cell ceasing to carry out its functions. This may be the result of the natural process of old cells dying and being replaced by new ones, as in programmed cell death, or may result from factors such as diseases, localized injury, or the death of the organism of which the cells are part.

Natural killer cells directly kill senescent cells, and produce cytokines which activate macrophages which remove senescent cells. [65] Senescent cells can be phagocytized by neutrophils as well as by macrophages. [66] Senolytic drugs which induce apoptosis in senescent cells rely on phagocytic immune system cells to remove the apoptosed 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 ...
