SENESCENCE. "Many invertebrates experience replicative senescence, though they never die of cancer." https://lnkd.in/dUX_Fna View in LinkedIn

DAILY DEATH FOR HEALTH. "During embryonic development of the nervous system, the finger digits, or the ovary, but also in adult organisms, minutely regulated daily death processes maintain health and integrity." http://mcb.berkeley.edu/courses/mcbc245/MCBC245PDFs/Jan31/Huettenbrenner2003.pdf View in LinkedIn

TELOMERE REPLENISHMENT. "Even one-celled organisms count replications, and will die if they don't replenish their telomeres with conjugation (sex)." https://lnkd.in/dUX_Fna View in LinkedIn

PREREQUISITES. "Cell-death programs as prerequisites of organized life." http://mcb.berkeley.edu/courses/mcbc245/MCBC245PDFs/Jan31/Huettenbrenner2003.pdf View in LinkedIn

DEATH BY TELOMERE. "A second 'deliberate' mechanism is called replicative senescence or cellular senescence. Metaphorically, a cell may be said to 'count' (with its telomeres) the number of times that it has divided, and after a set number of replications, it languishes and dies. It has been proposed that this mechanism evolved to suppress cancer." https://lnkd.in/dUX_Fna View in LinkedIn

SELF-PURGING. "Cell death is not only employed to remove damaged or infected cells, but it is also important for sculpting tissues. During embryonic development, animals produce many cells which are no longer needed in the adult animal and which therefore undergo PCD to eliminate themselves." (PCD = programmed cell death). https://celldeath.files.wordpress.com/2010/11/lopezself_munoz.pdf View in LinkedIn

PLANT Cell Death. "In plants, cell death is part of the normal cycle of the organism. Developmental cell death is observed in many plant tissues, being crucial for instance for senescence of leaves and flowers, formation of pollen and seeds and terminal differentiation of vascular elements. Moreover, plant cells undergo Programmed Cell Death in response to infection." https://celldeath.files.wordpress.com/2010/11/lopezself_munoz.pdf View in LinkedIn

"CELL DEATH regulated by a genetic program, or Programmed Cell Death (PCD), is a fundamental mechanism of homeostasis of tissues." https://celldeath.files.wordpress.com/2010/11/lopezself_munoz.pdf View in LinkedIn

SKIN DEATH. "A process involving programmed cell death which we are all familiar with is death of skin cells. The skin is constantly being renewed and this renovation involves death of cells in outer layers of the skin. These cells do not die by apoptosis, but by a process called ‘cornication’ or ‘keratinization’ of the outer layers of the epidermis." https://celldeath.files.wordpress.com/2010/11/lopezself_munoz.pdf View in LinkedIn

CELL DEATH BY MURDER. "Cytotoxic lymphocytes (CTL) and Natural Killer (NK) cells owe their names to their ability to induce death of their target cells. In order to avoid propagation of a virus, cytotoxic cells attack and kill the infected cells and they use several effector mechanisms in order to do so." https://celldeath.files.wordpress.com/2010/11/lopezself_munoz.pdf View in LinkedIn
