STAMP: Single-cell transcriptomics analysis and multimodal profiling through imaging.

Area of Science:

• Biotechnology
• Genomics
• Cell Biology

Background:

• Single-cell RNA sequencing offers insights into cellular diversity but faces limitations in scalability, cost, and cell preservation.
• Existing methods often destroy cells during analysis, hindering comprehensive profiling.

Purpose of the Study:

• To introduce STAMP (single-cell transcriptomics analysis and multimodal profiling), a novel, scalable, and cost-efficient approach for single-cell analysis.
• To enable multimodal profiling (RNA, protein, H&E) of millions of cells while preserving cellular morphology.

Main Methods:

• STAMP utilizes transcriptomics and proteomics imaging platforms, immobilizing cells onto slides for analysis.
• This method bypasses traditional sequencing costs, allowing for large-scale, cost-effective single-cell genomics.
• It supports simultaneous RNA, protein, and H&E staining for comprehensive cellular characterization.

Main Results:

• Demonstrated STAMP's effectiveness across diverse cell types, including peripheral blood mononuclear cells, cell lines, and stem cells.
• Successfully profiled over 10.9 million cells and 6 billion transcripts, showcasing high-quality data generation.
• Identified ultra-rare cell populations and simulated clinical applications, proving utility in large-scale studies.

Conclusions:

• STAMP significantly enhances the accessibility, scalability, and affordability of high-resolution cellular profiling.
• This technology overcomes key limitations of current single-cell sequencing methods.
• STAMP is poised to accelerate discoveries in cell biology and related fields.
