Quantification of Cytokine-Induced Cell Death in Human Colonic Organoids Using Live Fluorescence Microscopy

Overview

This study investigates the mechanisms of cell death in human colonic organoids in response to inflammatory cytokines like interferon gamma and TNF alpha. By utilizing a novel protocol involving fluorescent dyes and live microscopy, the research provides a robust method to quantify cell death at a single-organoid level.
