Scientists find out that by inserting young stem cells into aged brains it may help regenerate memories in older people.
Through this new technique, taking the donor neural stem cells and grafting them into an aged brain, findings showed that it may replace aging brain cells and restore memory.
Ashok K. Shetty, the lead scientist together with his team, implanted neural stem cell into the hippocampus (part of the brain that makes new memories and connects them to emotions) of an animal model to enable them to regenerate tissue.
Shetty explained, “We chose the hippocampus because it’s so important in learning, memory and mood function,”
“We’re interested in understanding aging in the brain, especially in the hippocampus, which seems particularly vulnerable to age-related changes.”
For this breakthrough, the team found that the well engrafted neural stem cells onto the hippocampus in the young animal models and even in the older ones, in human terms, about 70 years old.
Not only did these implanted cells last they also split several times to make new cells.
Scientists say, the fact that an aged hippocampus can accept grafted neural stem cells as good as the young hippocampus, it does means there is hope in treating age-related neurodegenerative disorders.
The team noted, “We are still producing new neurons at least 3 months after implantation, and these neurons are capable of migrating to different parts of the brain,”
Added that, if this research flourishes, it could have a noteworthy and remarkable discovery to revitalize the aged brain and combating aging.
Nevertheless, for most scientific experiments especially on the human body, despite conclusive results, but will definitely take series of stages, and even with FDA approval that is often a decade long process.
Still, researchers are optimistic that there is a new hope.
