Challenges in Translating Regenerative Therapies for Spinal Cord Injury

Following a spinal cord injury, the body's natural ability to repair itself is very limited. While animal models have shown promise, translating these findings into effective treatments for humans is challenging. Animal models used in research often don't fully replicate the complex nature of human spinal cord injuries, leading to difficulties in applying the research findings to real-world clinical situations. Factors such as publication bias, where only positive results are readily shared, and the focus on single primary outcomes in clinical trials, further complicate the translation of regenerative therapies.

• 1
  Species differences, particularly in lesion characteristics, anatomy, and metabolism, pose significant challenges to translating findings from rodent models to humans with spinal cord injury.
• 2
  The lack of variability in animal models, especially regarding sex, age, and injury type, contrasts with the heterogeneity of clinical spinal cord injuries in humans, hindering the development of broadly applicable treatments.
• 3
  Rehabilitative training is crucial for promoting recovery after spinal cord injury, yet its implementation varies significantly between animal studies and clinical practice, affecting the success of regenerative interventions.
