简介：
Overview
This study evaluates the proliferative effects of senescence-associated secretory phenotype (SASP) factors from senescent HeLa cells on non-senescent HeLa cells using three in vitro models with real-time monitoring. The advantages and limitations of each method were systematically compared to better understand cell-cell interactions in cancer.
