μCB-seq: microfluidic cell barcoding and sequencing for high-resolution imaging and sequencing of single cells

Area of Science:

• Biotechnology
• Genomics
• Cell Biology

Background:

• Single-cell RNA sequencing (scRNA-seq) offers high-resolution insights into complex biological systems.
• scRNA-seq cannot capture crucial phenotypic features like morphology or protein localization, limiting functional cell-state characterization.
• Quantitative optical microscopy excels at analyzing cellular phenotypes but is challenging to integrate with scRNA-seq due to difficulties in tracking individual cells.

Purpose of the Study:

• To develop a method for comprehensive single-cell analysis by integrating high-resolution imaging with gene expression profiling.
• To overcome the challenge of tracking single cells through both optical and sequencing measurements.
• To create a scalable and accurate platform for information-rich single-cell characterization.

Main Methods:

• Development of microfluidic cell barcoding and sequencing (μCB-seq) platform.
• Novel microfluidic device fabrication enabling preloaded primers with known barcodes in addressable reaction chambers.
• Integration of high-resolution imaging capabilities with single-cell sequencing.

Main Results:

• Successful combination of high-resolution imaging and gene sequencing within a single microfluidic platform.
• Demonstration of multi-modal single-cell analysis capabilities.
• Improved gene detection sensitivity compared to existing methods.

Conclusions:

• μCB-seq provides a scalable and accurate method for comprehensive single-cell analysis.
• This platform enables the functional integration of gene expression data with detailed cellular phenotypes.
• μCB-seq advances the field of single-cell biology by offering richer cellular information.
