Protocol for cutaneous wound healing assay in a murine model

Area of Science:

• Dermatology
• Regenerative Medicine
• Cell Biology

Background:

• Cutaneous wound healing is a complex biological process involving cell migration, intercellular communication, and gene regulation.
• Understanding these mechanisms is crucial for developing effective treatments for various wounds.
• Current research requires robust models to investigate cellular behaviors and therapeutic interventions.

Purpose of the Study:

• To present a standardized protocol for creating full-thickness cutaneous wounds in mice.
• To enable detailed histological, immunohistochemical, RNA, and protein analyses of wound healing.
• To facilitate the evaluation of novel therapeutic strategies for wound repair.

Main Methods:

• Generation of full-thickness cutaneous wounds on the dorsal skin of mice.
• Collection of biopsied wound materials at specific time points post-wounding.
• Histological and immunohistochemical analyses of tissue samples.
• RNA and protein extraction for molecular investigations.

Main Results:

• The described protocol allows for the generation of reproducible cutaneous wounds.
• The methodology supports comprehensive analysis of cellular and molecular events during wound healing.
• This model is suitable for assessing the efficacy of potential treatments.

Conclusions:

• The presented protocol provides a valuable tool for studying cutaneous wound healing in a preclinical setting.
• This model supports research into cell-autonomous and non-cell-autonomous functions during healing.
• The methodology aids in the development and testing of new drugs, compounds, and stem cell-based therapies for accelerated wound healing.
