Phenotypic alterations and PI3K-AKT pathway regulation in senescence of human tonsil mesenchymal stem cells

Puntos clave

This research aims to understand how the PI3K-Akt pathway influences the aging process in tonsil mesenchymal stem cells.
Analyzed tonsil mesenchymal stem cells (TMSCs) to observe changes during replicative senescence.
Studied the activation of the PI3K-Akt pathway and its relation to senescence markers like p16 and p53-p21.
Confirmed that TMSCs exhibit signs of replicative senescence with enhanced PI3K-Akt pathway activation.
Found that this pathway activates senescence-related cascades involving p16 and p53-p21, potentially affecting stem cell function.

Resumen

Our research proved that replicative senescence in TMSCs is associated with PI3K-Akt pathway activation, which likely orchestrates senescence via p16 and p53-p21 cascades. These findings provide new insights into the mechanisms of stem cell aging and suggest potential molecular targets for developing strategies to delay senescence in TMSCs for regenerative medicine.
