Stem Cells and Aging
The stem cells found within the average adult human are capable of restoring dying cells while also fixing damaged tissue. Nothing is safe from the aging process, though, and as we get older we begin to lose the very same stem cells that once kept our bodies in functional condition. But there could be a way around that: new stem cell research has revealed a nutrient sensing pathway called TOR can be subdued in order to prevent such loses. TOR plays a key role in the aging process and is largely responsible for the loss of stem cells in the human body.
