Old Transformed into Young Brain Cells
Nautilus | Science Connected • • science
Key Points:
- Scientists have developed a method to convert specialized blood cell progenitors from an elderly donor directly into neural stem cells, bypassing the intermediate pluripotent stem cell stage while maintaining a youthful molecular profile.
- This new technique gradually resets the cells' epigenetic age over about 100 days, resulting in brain cells with an epigenetic age of under 20 years, effectively rejuvenating them at the molecular level.
- The gradual rejuvenation process allows researchers to study factors that influence cellular aging more closely, providing a valuable experimental model for understanding how to accelerate or slow down cellular rejuvenation.
- Understanding the molecular aging of brain cells could provide insights into age-related neurodegenerative diseases like Alzheimer’s, as age remains the primary risk factor for these conditions.
