Wound-healing studies in transgenic and knockout mice

Area of Science:

• Wound healing research
• Molecular biology
• Genetics

Background:

• Skin injury triggers complex repair processes involving inflammation, new tissue formation, and remodeling.
• Animal models, particularly genetically modified mice, have been crucial in understanding the molecular orchestration of wound repair.
• Advanced genetic techniques overcome challenges like embryonic lethality, enabling tissue- or temporal-specific gene function studies.

Purpose of the Study:

• To review and summarize studies utilizing genetically modified mouse models to elucidate the in vivo roles of proteins in wound repair.
• To focus on the contributions of soluble mediators, including growth factor families, cytokines, and chemokines.
• To provide a comprehensive overview of current knowledge in this rapidly advancing field.

Main Methods:

• Analysis of published research employing genetically modified mouse models for wound healing studies.
• Focus on studies investigating the function of specific protein families: fibroblast growth factor (FGF) and transforming growth factor-beta (TGF-beta).
• Inclusion of data on cytokines and chemokines involved in the wound repair cascade.

Main Results:

• Genetically modified mouse models have identified the in vivo functions of nearly 100 proteins in wound repair.
• Significant insights have been gained into the roles of soluble mediators such as FGF and TGF-beta families.
• Data on the involvement of various cytokines and chemokines in the wound healing process has been compiled.

Conclusions:

• Genetically modified mouse models are powerful tools for dissecting the molecular mechanisms of wound repair.
• Understanding the roles of soluble mediators is critical for advancing wound healing therapies.
• A compendium of these studies is available online for ongoing research.
