Summary
Enzyme treatment for cell dissociation in RNA sequencing can alter gene expression. This study profiles these changes in mouse skeletal muscle cells to identify genes to exclude from analysis.
Area of Science:
- Molecular Biology
- Genomics
- Cell Biology
Background:
- Single-cell RNA sequencing (scRNA-seq) is crucial for understanding cellular heterogeneity.
- Cell isolation via enzymatic dissociation is a prerequisite for scRNA-seq.
- The impact of enzymatic dissociation on gene expression profiles remains incompletely understood.
Purpose of the Study:
- To comprehensively profile enzyme-dependent gene expression changes during cell dissociation.
- To investigate the influence of enzyme treatment time, concentration, and temperature.
- To provide reference data for optimizing RNA-seq protocols.
Main Methods:
- Mouse skeletal muscle progenitor cells were subjected to enzymatic dissociation using varying conditions.
- Gene expression profiles were analyzed using RNA sequencing.
- Changes in gene expression were correlated with enzyme treatment parameters (time, amount, temperature).
Main Results:
- Enzyme treatment significantly altered gene expression in a time-dependent manner.
- A subset of genes exhibited expression changes independent of enzyme treatment duration, amount, or temperature.
- Specific gene expression patterns were identified based on dissociation conditions.
Conclusions:
- Enzymatic dissociation introduces detectable gene expression alterations in scRNA-seq data.
- Understanding these enzyme-induced changes is critical for accurate data interpretation.
- This research provides essential data for selecting appropriate genes for analysis and refining cell isolation protocols.
