Area of Science:

• Genomics
• Molecular Biology
• Biotechnology

Background:

• Gene expression and regulation are fundamental to all living systems.
• Quantifying gene expression provides insights into biological processes.
• Current methods often lack the necessary individual and spatial resolution for complex biological questions.

Purpose of the Study:

• To highlight opportunities for engineering and method development in gene expression analysis.
• To address the need for high-density, high-quality gene expression data at single-animal and tissue-specific levels.
• To explore the potential of microfluidic technologies in enhancing single-animal gene expression assays.

Main Methods:

• Review of existing gene expression quantification techniques (e.g., RNA-sequencing, fluorescent reporters).
• Discussion of limitations in current single-animal and population-based assays.
• Exploration of microfluidic technologies for improved biological assays.

Main Results:

• Popular transcriptome quantification methods (e.g., RNA-sequencing) lack individual and spatial resolution.
• Existing single-animal assays face technical bottlenecks, including sample handling.
• Microfluidic technologies offer potential enhancements for single-animal gene expression studies.

Conclusions:
