Drug responses in 3D models develop gradually over time, affecting their morphology, viability, and functional behavior. Live-cell imaging allows researchers to monitor these changes as they unfold, rather than relying on isolated endpoint measurements. However, the complex structures of spheroids and organoids create challenges for conventional widefield imaging, where limited resolution and overlapping signals can obscure cellular details and complicate quantification.
This white paper examines how confocal live-cell imaging addresses these limitations through optical sectioning and depth-resolved measurements. Drawing on experimental comparisons and drug discovery applications, it demonstrates how improved signal clarity, multiplexed fluorescence, and automated analysis support more detailed assessments of treatment effects and cellular behavior.
