The Role of Neutrophils in Biomaterial-Based Tissue Repair-Shifting Paradigms

Area of Science:

• Biomaterials Science
• Immunology
• Regenerative Medicine

Background:

• Tissue engineering seeks clinical solutions for damaged tissues via endogenous repair or biomaterials.
• Understanding immune interactions with biomaterials is crucial for successful tissue regeneration.
• Neutrophils were traditionally viewed as short-lived cells in acute inflammation.

Purpose of the Study:

• To review the evolving understanding of neutrophil roles in tissue repair and biomaterial integration.
• To explore the plasticity and extended lifespan of neutrophils.
• To discuss neutrophils' potential in biomaterial-based immunomodulation for regenerative medicine.

Main Methods:

• Literature review focusing on neutrophil functions in inflammation resolution, biomaterial integration, and tissue regeneration.
• Analysis of recent findings on neutrophil plasticity and phenotype polarization.
• Discussion of immunomodulatory strategies involving neutrophils and biomaterials.

Main Results:

• Neutrophils exhibit plasticity and can adopt phenotypes beyond acute inflammation roles.
• Activated neutrophils have increased longevity, contributing to later stages of healing.
• Neutrophils are critical for successful biomaterial-tissue integration and subsequent regeneration.

Conclusions:

• Neutrophils are key players in resolving inflammation and promoting tissue repair.
• Their immunomodulatory potential can be harnessed for biomaterial-based therapies.
• Revisiting neutrophil functions opens new avenues in tissue engineering and regenerative medicine.
