Later on, this cell response was identified both in vitro and in vivo for cells subjected to different forms of stress, and more recently it has also been involved in physiological situations during development. although not following a predictable pattern, . The final stage of petal development is associated with flower senescence, which is an irreversible process involving programmed cell death, and premature senescence of cut flowers often results in major losses in quality during postharvest handling.

Autumn leaf senescence in Populus, shares many features with leaf senescence in annual plants ; however, the induction of autumn senescence remained to be studied. Emphysema is one of the causes of chronic obstructive pulmonary disease (see airway response to injury). Depletion of sodium and potassium. in cultured cells, senescence can be triggered by replicative exhaustion, or in response to activated oncogenes, dna damage, or oxidative stress ( courtois-cox et al., 2008 )., accordingly, the senescence program acts as a general anti-proliferative stress response and is considered a potent tumor suppressive mechanism in vivo [reviewed in ( The process that divides different portions of the zygote's cytoplasm among blastomeres is called _____.

At the beginning of a human pregnancy, the embryo implants into the uterus lining, known as the endometrium. The senescence program typically involves a blockade to proliferation followed by clearance mediated by immune cells, leading to the elimination of cells that undergo an unrepairable level of damage or are no longer required for normal tissue function. Because of underlying differences in the aging of mice and humans, useful mouse models have been difficult to obtain and study.
