Multiplexed Epitope-Based Tissue Imaging for Discovery and Healthcare Applications

Area of Science:

• Biomedical Research
• Molecular Pathology
• Cellular Biology

Background:

• Understanding health and disease requires molecular-level analysis of organs and tissues.
• Emerging highly multiplexed epitope-based imaging techniques offer unprecedented insights.
• These methods enable simultaneous analysis of numerous epitopes in thousands of cells.

Purpose of the Study:

• To review highly multiplexed epitope-based imaging approaches and their generated data.
• To describe challenges in implementing these methods from bench to bedside.
• To discuss integration with multi-omics data and novel applications in biomedical research.

Main Methods:

• Serial imaging of tissues with fluorescently labeled antibodies.
• Simultaneous analysis using metal-labeled antibodies.
• High-throughput data generation for systems-level analysis.

Main Results:

• Enables analysis of dozens of epitopes in thousands of cells per experiment.
• Provides a systems-level view of normal and disease processes at single-cell resolution.
• Highlights potential for integration with genome, transcriptome, metabolome, and live cell data.

Conclusions:

• Highly multiplexed epitope-based imaging complements existing methods.
• These approaches are poised to become a cornerstone in tissue biology and biomedical research.
• Applications span drug development, biomarker discovery, and precision medicine.
