Autophagy in stem cell aging
Aging is responsible for changes in mammalian tissues that result in an imbalance to tissue homeostasis and a decline in the regeneration capacity of organs due to stem cell exhaustion. Autophagy is a constitutive pathway necessary to degrade damaged organelles and protein aggregates. Autophagy is one of the hallmarks of aging, which involves a decline in the number and functionality of stem ce...
متن کاملStem cell aging.
202 W E summarize here the fruitful discussion that occurred on a wide variety of topics during the session on stem cell aging. Somatic Stem Cell Aging Do stem cells age; and if they do, how can these changes be reliably identifi ed? Most attendees were of the view that a decline in the function of tissue-specifi c somatic stem cells is likely to play an important role in human aging. Results f...
متن کاملReversing stem cell aging
The stem cell theory of aging postulates that aging is the result of the failure of tissue specific stem cells to replenish tissues and to sustain tissue function. Stem cell functions decline with age, consistent with the degeneration and dysfunction of aging regenerative tissues. Stem cell dysfunction is associated with premature aging and evidence is emerging to suggest that stem cell manipul...
متن کاملHematopoietic stem cell aging.
Aging is organized in a hierarchy, in which aging of cells results in aged tissues, ultimately limiting lifespan. For organ systems that also in the adult depend on stem cells for tissue homeostasis like the hematopoietic system that forms immune cells, it is believed that aging of the stem cells strongly contributes to aging-associated dysfunction. In this review, we summarize current aspects ...
متن کاملAutophagy in stem cell maintenance and differentiation.
Autophagy is a lysosome-dependent degradation pathway that allows cells to recycle damaged or superfluous cytoplasmic content, such as proteins, organelles, and lipids. As a consequence of autophagy, the cells generate metabolic precursors for macromolecular biosynthesis or ATP generation. Deficiencies in this pathway were associated to several pathological conditions, such as neurodegenerative...
