Fluidic Logic Used in a Systems Approach to Enable Integrated Single-Cell Functional Analysis.

Area of Science:

• Single-cell biology
• Genomics
• Molecular biology

Background:

• Single-cell analysis has advanced, revealing heterogeneity within cell populations.
• Current methods struggle to link single-cell functional differences to genomic and transcriptomic data.
• Controlled perturbation and response monitoring at the single-cell level remain challenging.

Purpose of the Study:

• To develop an integrated platform for studying single-cell function.
• To bridge the gap between single-cell functional responses and molecular profiles.
• To enable routine functional studies of individual cells.

Main Methods:

• Development of an elastomer-based integrated fluidic circuit for cell selection and sequestration.
• On-chip culture, stimulation, and image-based response analysis of sequestered single cells.
• Preparation of mRNA transcriptomes for massively parallel sequencing.

Main Results:

• A miniaturized platform integrating multiple experimental steps for single-cell analysis was created.
• The system successfully selected and sequestered single cells based on phenotypic traits.
• Downstream genomic and transcriptomic analysis of functional responses was enabled.

Conclusions:

• The developed platform facilitates the routine functional study of single cells.
• This technology allows for the direct linkage of cellular function to genomic and transcriptomic information.
• The integrated system advances the understanding of single-cell heterogeneity and function.
