Integrated real-time imaging of executioner caspase dynamics, apoptosis-induced proliferation, and immunogenic cell death using a stable fluorescent reporter platform.

ABSTRACT: Regulated cell death plays a central role in tissue homeostasis, disease progression, and therapeutic responses. However, tools to study these processes with high spatiotemporal resolution in physiologically relevant systems remain limited. Here, we present a fluorescent reporter cell system that enables real-time visualization of caspase-3/-7 activity via a DEVD-based biosensor, alongside a constitutive fluorescent marker for assessing successful transduction and cell presence. We generated stable cell lines expressing this reporter and adapted them to both 2D and 3D culture systems, including organoids. This platform allowed dynamic tracking of apoptotic events and viability loss at single-cell resolution. Using a proliferation dye, we also detected apoptosis-induced proliferation in nei
