Cellular Reprogramming
Also: Partial Reprogramming
A research technique that resets aged cells to a more youthful state by activating a small set of genes, without erasing the cell's identity.
Cellular reprogramming builds on Nobel Prize-winning research showing that a small set of genes, often called Yamanaka factors, can reset a cell's molecular age markers. Full reprogramming turns a cell all the way back to a stem-cell-like state. Partial reprogramming aims to reverse some aging markers while keeping the cell's original identity and function intact.
The appeal for longevity research is the possibility of restoring youthful cell function without erasing what the cell does. This remains an active, high-uncertainty research area, with safety and long-term effects still under study, mostly in animal models.
