Scientists Made an 80-Year-Old’s Cells Look 19 Years Old. Could It Mean Aging Is Reversible?
Key Points:
- Researchers at the University of Bonn discovered that reprogramming red blood cell precursors can rewind their molecular age by over 60 years, effectively rejuvenating the cells.
- Unlike traditional methods that convert cells into pluripotent stem cells before neural stem cells, the team directly converted blood cells into neural stem cells using two transcription factors, allowing gradual rejuvenation over 100 days.
- The study tracked molecular aging using DNA methylation and RNA sequencing, showing cells from an 80-year-old appeared less than 20 years old post-reprogramming and exhibited youthful cellular behaviors such as reduced mitochondrial toxicity.
- This gradual rejuvenation process provides new insights into the mechanisms of cellular aging and holds potential for developing therapies targeting neurodegenerative diseases linked to aging.
