aging

Post by dadaliujia » Sat Aug 18, 2007 9:20 am

Cells lose water in the process of aging, and become obviously shrinked. The function of the cells can be influenced greately by the changing of water content.

Can somebody give me an explanaion why and how the water losing occurs in the aging events.

I wonder if the dehydration of aging somatic cells is the cause of aging or just a consequece of it.

Where did you get this information? I know of no such relationship - cells don't lose water with age.

I can't access the original, but articles that use it as a reference talk about general dehydration and loss of interstitial fluid, which makes sense with how aging compromises the skin.

That is also the way I learned it: the interstitial fluid is the one losing water, not the cytoplasm of cells.
I am afraid that most cells in the organism would die upon dehydration, due to imbalances in pH and osmosis.
