Unlocking the Full Potential of Organoid Imaging: Challenges and Pro Tips

Organoid culture has revolutionized scientific research, offering a powerful means to model complex mammalian tissues in vitro. Traditionally, characterizing organoids involved slow and labor-intensive methods like paraffin embedding and sectioning, limiting their utility for compound screening or drug development. The emergence of high-throughput analysis approaches, particularly leveraging automated high-content imaging platforms, has transformed the landscape.

Challenges in Organoid Imaging

 While the benefits are immense, 3D imaging of organoid cultures comes with challenges. The thickness and opacity of organoids hinder light penetration, and their dynamic nature requires time-lapse imaging, leading to potential phototoxicity. Structural integrity maintenance during imaging, data volume concerns, and maintaining natural biology are additional complexities.

Solutions with Hermes Imaging System

Overcoming these challenges demands innovative solutions. The Hermes imaging system integrates seamlessly with external liquid handlers or incubated plates stackers, facilitating long-term growth with media exchanges. The patented laser-based autofocus procedure addresses imaging issues arising from U-shaped bottom microplate labware. Its advanced features, such as stationary sample, rare event detection, and multichannel z-stack imaging, coupled with the WiSoft Athena analysis software, enhance the imaging of entire organoid samples while maintaining structural integrity.

Tips and Tricks for Successful Organoid Imaging

For newcomers to organoid imaging, optimizing protocols is key. Testing different concentrations, permeabilization techniques, and incubation times can enhance penetration of antibodies and stains. The use of clearing reagents, growth media optimized for fluorescent imaging, and well-matched fluorescent labels further refines imaging quality.

Advanced Imaging Protocols

For rare-event detection, employing lower magnifications initially and transitioning to higher magnifications as needed is recommended. Researchers new to extended time-lapse microscopy should consider a learning curve, balancing imaging intervals and phototoxicity, with control wells for reference.
