ZEISS and Harvard Advance 3D Spatial Biology for Cancer Research
ZEISS is collaborating with Harvard's Laboratory of Systems Pharmacology (LSP) to advance 3D spatial biology, focusing on whole-cell segmentation and confocal optical sectioning for cancer research. This initiative aims to visualize cellular structures and vascular features across tissue depths, preserving their spatial relationship to surrounding tissue. The CyCIF process, developed at LSP, utilizes iterative cycles of staining, imaging, and bleaching with open-source reagents and protocols. Each round incorporates a nuclear marker for reliable 3D registration. This method generates massive datasets, ranging from 200 to 900 terabytes, across dozens of channels, enabling high-plex 3D imaging. The goal is to understand how immune and tumor cells are arranged within complex tissue microenvironments, particularly in melanoma, by mapping cellular communities and visualizing vascular structures in three dimensions.
