Stress relief: emerging methods to mitigate dissociation-induced artefacts

Area of Science:

• Molecular Biology
• Genomics
• Bioinformatics

Background:

• Single-cell RNA sequencing (scRNA-seq) has advanced significantly, enabling large-scale transcriptional mapping of multicellular tissues.
• Generating comprehensive cell atlases requires scalability, spatial context, and individual cell transcriptome accuracy.

Purpose of the Study:

• To discuss the impact of traditional cell isolation on native transcriptional signatures.
• To review methods developed to overcome these limitations.
• To highlight biological discoveries enabled by improved scRNA-seq approaches.

Main Methods:

• Analysis of limitations in traditional cell isolation protocols for scRNA-seq.
• Review of novel methodologies preserving in situ cellular information.
• Integration of spatial transcriptomics data.

Main Results:

• Traditional protocols can distort cellular transcriptional profiles.
• New methods preserve native cell states and spatial relationships.
• Advancements facilitate deeper understanding of tissue heterogeneity and cell function.

Conclusions:

• Improved scRNA-seq techniques are crucial for accurate tissue mapping.
• Preserving spatial and transcriptional integrity is key to uncovering biological mechanisms.
• Large-scale scRNA-seq is revolutionizing cell biology and disease research.
