Even in the adult brain, its plasticity is much stronger than people originally thought, but with the increase of age, many people will eventually suffer from diseases such as dementia and cognitive dysfunction. However, the latest research by American scientists shows that in the future, it is expected to use neural stem cells to regenerate human brain cells and help restore memory.
According to the Daily Science website, recently, the Deputy Director of the American Institute of Regenerative Medicine, Ashke Shetty, and her team transplanted the extracted neural stem cells into the hippocampus and found that it helped restore memory. Related research is published in the journal Stem Cell Translation Medicine.
According to Shetty, hippocampus plays an important role in learning, memory and emotional control, but as the age increases, the volume will shrink, resulting in a significant decline in memory. Age-related degenerative diseases such as chronic inflammation can also occur in the aged hippocampus in the brain.
The team's latest research found that transplanting neural stem cells into the hippocampus of young animals and the hippocampus of older animals has the same effect. These transplanted neural stem cells not only survive, but also differentiate and regenerate, which helps treat neurodegenerative diseases associated with aging.
Shetty said that compared with fetal neurons, neural stem cells and other pluripotent stem cells can endure the hypoxic and traumatic brain microenvironment during transplantation, thus achieving better results than indirect nuclear division or relatively mature neurons. In stroke and brain trauma conditions, neural stem cells can also feedback the injury signal and replace some of the missing cerebral cortical neurons.
Shetty also said: "It is not necessary to get cells from the brain." In the near future, a large number of neural stem cells of the same species can be obtained from the skin, and a large number of somatic cells including skin cells can be induced to produce pluripotent stem cells. Scientists can do a lot of things through these cells, including the use of extracted neural stem cells to produce more neural stem cells or new neurons.
Shetty's previous research focused on the beneficial effects of resveratrol (an antioxidant, red wine, peanuts and some berries) on the hippocampus. Although the results of the study indicate that resveratrol is beneficial in preventing memory decline, the latest research results have found a more direct way to influence hippocampal function.
