Spatial omics and multiplexed imaging to explore cancer biology

Area of Science:

• Oncology
• Molecular Biology
• Biotechnology

Background:

• Intratumoral heterogeneity, the molecular variation within tumors, is key to understanding cancer biology.
• Single-cell analyses (e.g., RNA sequencing) have identified cancer biomarkers but lose spatial context.
• Understanding cellular location is crucial for a complete picture of tumor biology.

Purpose of the Study:

• To review current and future spatial technologies for cancer research.
• To highlight advancements in mapping intratumoral heterogeneity.
• To discuss the impact on cancer diagnostics and therapeutics.

Main Methods:

• Leveraging multiplexed labeling (DNA, RNA, isotope) for spatial detection.
• Utilizing fluorescence-based techniques.
• Integrating multiomics data with spatial information.

Main Results:

• Spatial technologies enable detection of numerous cancer subclones and biomarkers in situ.
• These methods preserve the native spatial context of cells within the tumor microenvironment.
• Advancements promise a more comprehensive understanding of cell-to-cell variation.

Conclusions:

• Spatial technologies are revolutionizing cancer research by providing unprecedented spatial insights.
• These techniques are expected to drive next-generation diagnostics and therapeutic strategies.
• A comprehensive understanding of tumor biology necessitates integrating spatial information.
