Cellular Senescence Detection Comparison
Cellular senescence is considered crucial to many different research areas, especially since the recent discovery of the senescence-associated secretory phenotype (SASP). SASP is a known risk factor for malignant transformation and exploration into stem cell research has found a link between SASP and the aging phenomenon. The features of cellular senescence were summarized based on modern publications that have a high number of citations.

Feature of Cellular Senescence
Evaluate senescent cells from various makers
In WI-38 cells at different passages SA-ß-Gal activity, mitochondrial membrane potential, and cellular metabolism (Glucose and Lactate) were evaluated using each specific kit. In senescent cells, SA-ß-Gal activity was enhanced and mitochondrial membrane potential was reduced. Consumption of Glucose and lactate level in the supernatant measured as an indicator of metabolism was increased.
