Rapid Clearing for High Resolution 3D Imaging of Ex Vivo Pancreatic Cancer Spheroids
Research Overview
Imaging methods have been the central obstacle to seeing fine detail in 3D ex vivo tumor models. This study developed a simple, efficient procedure using standard reagents and imaging equipment that significantly enhanced 3D imaging to roughly 200 µm depth.
The method was tested on pancreatic spheroids — prototypes of dense tissue that are notoriously hard to image — and both saved time and extracted information about pancreatic tumor spheroids that had previously been difficult to obtain, including clear differences in tumor organization.
Key Discoveries
- Rapid clearing procedure extended high-resolution 3D imaging to ~200 µm depth
- Uses standard reagents and imaging equipment — no specialized instrumentation
- Validated on dense pancreatic tumor spheroids that resist conventional imaging
