Description

Xylena Reed and co-authors present a 2026 study on whether aging marks on DNA survive the reprogramming of blood cells into stem cells. Chemical tags on DNA shift with age and shape how cells work. Stem cells made from a person's own cells are widely used in research, so it matters whether they keep the donor's age marks or reset them.

The team took blood cells from 99 healthy adults in an aging study and reprogrammed them into stem cells. Genome-wide tag maps were then compared between the two cell types. Age-related tags were largely reset by reprogramming. The result supports using such stem cells to study disease without age as a built-in bias.
