Preclinical animal models in trauma research

Area of Science:

• Biomedical research
• Veterinary medicine
• Comparative pathology

Background:

• Preclinical animal models are essential for studying human diseases, but lack standardization across various pathological conditions.
• Current literature interpretation is challenging due to the use of diverse and often physiologically irrelevant animal models.
• Inconsistent model selection, often based on convenience rather than accuracy, complicates research and funding applications.

Purpose of the Study:

• To address the lack of standardization in preclinical animal modeling for common diseases.
• To review current literature and commonly used animal models for osteoporosis, infection, bone defects, and cartilage injury.
• To propose preferred preclinical models for future research to enhance study design and interpretation.

Main Methods:

• Literature review of existing preclinical animal models for specific diseases.
• Analysis of the relevance and physiological accuracy of commonly employed models.
• Identification and recommendation of superior models for future research.

Main Results:

• Significant variability exists in animal models used for preclinical disease research.
• Many current models are chosen for practical reasons (e.g., size, ease of use) rather than accurate disease representation.
• A need for standardized, physiologically relevant models is evident across multiple disease areas.

Conclusions:

• Standardization of preclinical animal models is urgently needed for reliable disease research.
• Adoption of preferred, validated models will improve the quality of scientific literature and research design.
• Improved preclinical model selection will facilitate advancements in understanding disease pathogenesis and developing effective treatments.
