Spinal cord injury modeling: from modeling to evaluation using rats as examples

Area of Science:

• Neuroscience
• Regenerative Medicine
• Surgical Research

Background:

• Spinal cord injury (SCI) significantly impacts patient quality of life and presents a major challenge in medical research.
• Standardizing SCI models is crucial for reducing experimental variability and advancing therapeutic strategies.
• Existing literature inadequately details comprehensive guidelines for SCI model construction beyond initial selection.

Purpose of the Study:

• To provide a practical, detailed guide for researchers constructing experimental spinal cord injury models.
• To address critical factors often overlooked in SCI model creation, including anesthesia, surgical technique, and postoperative care.
• To promote standardization in SCI modeling to enhance the reliability of preclinical research and facilitate the development of effective treatments.

Main Methods:

• Compilation of experimental experience from a dedicated research team in SCI modeling.
• Integration of findings from relevant scientific literature on SCI model construction and management.
• Systematic review of critical parameters including animal selection, injury severity, anesthesia, surgical procedures, and postoperative care.

Main Results:

• Identification of key variables influencing SCI model consistency and reproducibility.
• Detailed recommendations for anesthesia, analgesia, surgical techniques, and complication management.
• Guidelines for sample collection and post-injury spinal cord evaluation methods.

Conclusions:

• Standardized SCI models are essential for robust preclinical research and the development of novel therapeutic interventions.
• This practical guide offers a framework to improve the consistency and reliability of SCI model construction.
• Adherence to these guidelines will lay a stronger foundation for future SCI research and clinical translation.
