Scientists reverse more than 60 years of cellular aging in lab-grown human cells

· Science

Researchers have converted blood cells from an 80-year-old into neural stem cells with a molecular age of under 20, effectively reversing more than 60 years of cellular aging in the laboratory, according to a ScienceDaily report. The work offers a new route for studying how cells become younger and could help researchers better understand age-related disease. The item does not name the research team, the journal or the specific reprogramming method used, so the result should be read as a laboratory finding rather than a therapy. The immediate effect is to add a tool for aging research: cells that appear molecularly younger give scientists a way to compare young and old states of the same lineage and to probe what drives decline with age.

Why it matters：Cellular reprogramming is central to aging research and regenerative medicine; a method that rolls back decades of molecular age gives labs a new way to study age-related disease.

Key points

  • Blood cells from an 80-year-old were turned into neural stem cells.
  • The resulting cells had a molecular age of less than 20.
