Infected animal models for tissue engineering.

Area of Science:

• Biomedical Engineering
• Infectious Diseases
• Regenerative Medicine

Background:

• Infections are common complications of medical interventions and implants.
• Tissue engineering advancements necessitate research into preventing and treating associated infections.
• In vitro models cannot fully replicate the complex in vivo environment for infection studies.

Purpose of the Study:

• To review considerations for selecting appropriate animal models for infection research.
• To discuss established animal models for cutaneous, fascial, and orthopedic infections.
• To identify areas needing further development in infection model systems.

Main Methods:

• Literature review of animal models for medical intervention-associated infections.
• Analysis of established models for specific infection types (cutaneous, fascial, orthopedic).
• Discussion of challenges and future directions in animal model development.

Main Results:

• Animal models are essential for evaluating the safety and efficacy of experimental infection treatments.
• Specific considerations exist for choosing models based on infection site and research goals.
• Existing models require further refinement to accurately represent in vivo infection dynamics.

Conclusions:

• Appropriate animal models are critical for advancing treatments for implant-associated and tissue engineering infections.
• Further development of infection models is needed to improve translational research.
• This review provides a framework for selecting and developing relevant animal models.
