Epidermal stem cells: Interplay with the skin microenvironment during wound healing

Area of Science:

• Dermatology
• Stem Cell Biology
• Tissue Engineering

Background:

• Skin possesses a natural turnover and is frequently injured.
• Wound healing is a complex biological process involving multiple cell types and signaling pathways.
• Epidermal stem cells (EpdSCs) are key players in skin repair due to their self-renewal and differentiation capabilities.

Purpose of the Study:

• To review the complex interactions between epidermal stem cells (EpdSCs) and their microenvironment during skin wound healing.
• To elucidate the roles of EpdSCs and their surrounding components in tissue repair and barrier restoration.

Main Methods:

• Literature review focusing on the interplay between EpdSCs and microenvironmental factors.
• Analysis of signaling pathways and cellular interactions in skin regeneration.
• Examination of the roles of extracellular matrix, vasculature, and immune cells in supporting EpdSC function.

Main Results:

• EpdSCs actively interact with the extracellular matrix, fibroblasts, endothelial cells, and immune cells.
• These interactions are critical for successful re-epithelialization and restoration of the skin barrier.
• The microenvironment significantly influences EpdSC behavior and contribution to tissue repair.

Conclusions:

• Epidermal stem cells (EpdSCs) are pivotal in wound healing, orchestrating repair through dynamic interactions with their microenvironment.
• Understanding these intricate cellular and matrix crosstalks is essential for advancing therapies for skin repair and regeneration.
• Targeting EpdSC-microenvironment communication holds promise for improving outcomes in skin injury treatment.
