The world’s first successful identification and characterization of in vivo senescent cells

The world's first successful identification and characterization of in vivo senescent cells
The research team generate a p16-Cre ERT2 – tdTomato mouse model to uncover the in vivo dynamics and properties of p16high cells. Single-cell RNA-seq analyses of various tissues from early middle-aged p16-CreERT2-tdTomato mice reveal that p16high cells exhibit heterogenous senescence-associated phenotypes, while elimination of p16high cells ameliorates steatosis and inflammation in a NASH model.

Cell senescence is a state of permanent cell cycle arrest that was initially defined for cells grown in cell culture. It plays a key role in age-associated organ dysfunction and age-related diseases such as cancer, but the in vivo pathogenesis is largely unclear.


A research team led by Professor Makoto Nakanishi of the Institute of Medical Science, the University of Tokyo, generated a p16-Cre ERT2 -tdTomato mouse model to characterize in vivo p16 high cells at the single-cell level.

They found tdTomato-positive p16 high cells detectable
