When a Cell Fell in Love

Cervical adenocarcinoma (HeLa) cells were cultured onto a glass-bottom MatTek dish in Eagle’s minimum essential medium (EMEM) supplemented with 10% fetal bovine serum, 2.5 mM L-Glutamine, 1.0 mM sodium pyruvate and 2.5 mM sodium bicarbonate, and maintained at 37ºC and 5% CO2. HeLa cells were transiently co-transfected with GFP-tubulin and a membrane-tagged caspase biosensor (that was developed by inserting a caspase cleavage site between a myristoylation sequence and mApple), using Lipofectamine 2000 according to manufacturer’s instructions. After 6 h of transfection, cells were allowed to grow in fresh media overnight. The next day, cells were subjected to live-cell imaging using an Andor Dragonfly 505 confocal imaging system.
