Mouse Wound Models and Preparation of Single-Cell Suspensions

Area of Science:

• Regenerative Medicine
• Molecular Biology
• Dermatology

Background:

• Managing acute full-thickness skin injuries is clinically challenging due to complex wound healing processes.
• Traditional methods struggle to assess treatment effects in intricate wound microenvironments.
• Single-cell transcriptome sequencing offers insights into wound healing but is sensitive to model variability and tissue dissociation challenges.

Purpose of the Study:

• To optimize mouse wound models for precise wound closure assessment, minimizing variables affecting subsequent sequencing.
• To evaluate cost-effectiveness and efficiency of enzyme-based versus kit-based protocols for single-cell suspension preparation.

Main Methods:

• Standardized construction of mouse wound models to control variables.
• Comparative analysis of enzyme preparation and commercial test kit protocols for dissociating mouse skin tissues.
• Assessment of single-cell suspension quality for downstream transcriptome sequencing.

Main Results:

• Optimized mouse wound models enable accurate assessment of wound closure dynamics.
• Both enzyme and kit-based protocols can yield high-quality single-cell suspensions.
• Cost-effectiveness analysis will guide protocol selection for specific research needs.

Conclusions:

• Standardized mouse wound models are crucial for reliable wound healing research using single-cell technologies.
• Optimized tissue dissociation protocols are essential for generating high-quality single-cell suspensions.
• The findings provide a foundation for more accurate investigations into skin injury repair mechanisms.
