Prevention of Age-Related Brain Loss with Stem Cells

In advanced aging, a cognitive decline is typically observed as the years go by. But scientists may have an answer for this dilemma as stem cell research has found a novel approach to slow and possibly prevent this phenomenon.

Giving rise to new nerve cells every single day, the adult brain contains highly “regenerative” stem cells. As the brain ages, the number of stem/progenitor cells and their progeny decline dramatically according to previous studies. The number of stem cells we have in old age could be preserved in by boosting the number of stem cells when we are young or middle aged according to Dr. Rietze and his team.

The number of stem cells typically found in the brain is increased by using two separate approaches. Stimulating resident stem cells to divide and increase in number, the first approach used by Dr. Rietze and his team involves performing an acute infusion of growth hormone directly into the brain. These results indicate that a new target for stem cell-related treatments may be growth hormone, which may also play an integral role in regulating brain stem cells.
