Identification of Functional Cellular Markers Related to Human Health, Frailty and Chronological Age

Aging Cell, Volume 24, Issue 9, September 2025.
Human skin fibroblasts in vitro preserve the memory of age and health. ABSTRACT Aging leads to a decline in physiological reserves, an increase in age‐related diseases, reduced functional ability and a shortened healthspan. While molecular markers of chronological aging exist, their link to general health and intrinsic capacity (IC), a composite ...
