The successful introduction of innovative treatment strategies into clinical practise strongly depends on the availability of effective experimental models and their reliable pre-clinical assessment. Considering pre-clinical research for peripheral nerve repair and reconstruction, the far most used nerve regeneration model in the last decades is the sciatic nerve injury and repair model. More recently, the use of the median nerve injury and repair model has gained increasing attention due to some significant advantages it provides compared to sciatic nerve injury. Outstanding advantages are the availability of reliable behavioural tests for assessing posttraumatic voluntary motor recovery and a much lower impact on the animal wellbeing. In this article, the potential application of the median nerve injury and repair model in pre-clinical research is reviewed. In addition, we provide a synthetic overview of a variety of methods that can be applied in this model for nerve regeneration assessment. This article is aimed at helping researchers in adequately adopting this model for pre-clinical evaluation of peripheral nerve reconstruction as well as for interpreting the results in a translational perspective.
创新治疗策略成功引入临床实践在很大程度上取决于有效的实验模型及其可靠的临床前评估。考虑到周围神经修复和重建的临床前研究,在过去几十年中使用最为广泛的神经再生模型是坐骨神经损伤和修复模型。最近,正中神经损伤和修复模型的使用越来越受到关注,因为与坐骨神经损伤相比,它具有一些显著优势。突出的优势在于有可靠的行为测试来评估创伤后自主运动恢复情况,并且对动物健康的影响要小得多。本文综述了正中神经损伤和修复模型在临床前研究中的潜在应用。此外,我们综合概述了可应用于该模型进行神经再生评估的各种方法。本文旨在帮助研究人员充分采用该模型进行周围神经重建的临床前评估,并从转化的角度解释结果。
