Old Blood Cells Have Been Transformed Into Brain Stem Cells That Get Younger As They Age
Researchers at the University of Bonn have successfully transformed old human blood cells into young neural stem cells using a direct conversion method. This breakthrough suggests that cellular aging can be reversed, offering potential new avenues for regenerative medicine.
Why it matters
This discovery could fundamentally change how we treat neurodegenerative diseases by allowing for the creation of youthful, patient-specific brain cells.
Aging is the price paid for the ability of experiencing existence , one might philosophize.
Natural cellular aging begins with differentiation. Once a stem cell becomes a specific cell type, it's locked in forever: fat cells can never become muscle cells, no matter how hard one wishes, or pokes and prods at them in front of the mirror.
Or so it goes in nature, but scientists can definitely transform cells, as if biologically compensating for all the failed alchemical attempts of the past.
Now, scientists have transformed old blood cells into young brain stem cells , which continued to grow younger as they grew older.
The researchers, from the University Hospital of Bonn and the University of Bonn, in Germany, described their methods in the journal Aging Cell .
