Course Details
Overview
Advance your expertise in 3D cell culture with this comprehensive hybrid workshop focusing on reproducible spheroid generation, real-time oxygen monitoring, hypoxia profiling, and functional mitochondrial analysis.
This intensive training program combines two online theory days with four days of hands-on laboratory training, providing participants with a complete workflow from spheroid generation to advanced functional characterization. Using MicroSpheres™, SensoSpheres™, MicrosCube™ oxygen sensing technology, fluorescence microscopy, confocal imaging, and mitochondrial stress testing, participants will gain practical experience with cutting-edge tools increasingly used in pharmaceutical research, cancer biology, toxicology, tissue engineering, and organ-on-chip development.
Unlike conventional 3D culture courses that focus primarily on morphology, this workshop emphasizes the functional biology of spheroids. Participants will learn how oxygen availability shapes cellular behavior, how mitochondrial function can be measured in three-dimensional tissues, and how physiological parameters can be integrated with imaging data to generate biologically meaningful insights.
Throughout the course, participants will design experiments, generate spheroids, perform staining procedures, collect real-time oxygen measurements, conduct mitochondrial stress tests, analyze their own datasets, and discuss how these technologies can be implemented in their own research projects.
Prerequisites
This advanced course is recommended for participants who have:
- Prior experience with mammalian cell culture
- Basic understanding of 3D cell culture systems
- Experience with fluorescence microscopy is beneficial
- Completion of an introductory 3D Cell Culture course or equivalent experience
Learning Objectives

- Operate fluorescence and confocal microscopes for spheroid analysis
- Monitor oxygen dynamics under normoxic, hypoxic and hyperoxic conditions
- Design and execute 3D mitochondrial stress tests
- Analyze oxygen consumption profiles and mitochondrial responses
- Integrate imaging, oxygen sensing and functional assay data
- Apply these workflows to drug screening, disease modelling and organ-on-chip systems
