Quantifying Cell Death in Human Colonoids in Response to Cytotoxic Perturbagens

This protocol describes a simple and cost-effective method to investigate and quantify cell death in human colonic organoids in response to cytotoxic perturbagens such as cytokines. The approach employs a fluorescent cell death dye (SYTOX Green Nucleic Acid Stain), live fluorescence microscopy, and open-source image analysis software to quantify single-organoid responses to cytotoxic stimuli.
