Abstract
- Spinal cord injury (SCI) is a devastating disease with limited effective treatment options. Animal paradigms are vital for understanding the pathogenesis of SCI and testing potential therapeutics. The porcine model of SCI is increasingly favored because of its greater similarity to humans. However, its adoption is limited by the complexities of care and range of testing parameters. Researchers need to consider swine selection, injury method, post-operative care, rehabilitation, behavioral outcomes, and histology metrics. Therefore, we systematically reviewed full-text English-language articles to evaluate study characteristics used in developing a porcine model and summarize the interventions that have been tested using this paradigm. A total of 63 studies were included, with 33 examining SCI pathogenesis and 30 testing interventions. Studies had an average sample size of 15 pigs with an average weight of 26 kg, and most used female swine with injury to the thoracic cord. Injury was most commonly induced by weight drop with compression. The porcine model is amenable to testing various interventions, including mean arterial pressure augmentation ( n = 7), electrical stimulation ( n = 6), stem cell therapy ( n = 5), hypothermia ( n = 2), biomaterials ( n = 2), gene therapy ( n = 2), steroids ( n = 1), and nanoparticles ( n = 1). It is also notable for its clinical translatability and is emerging as a valuable pre-clinical study tool. This systematic review can serve as a guideline for researchers implementing and testing the porcine SCI model.<br />Competing Interests: Nicholas Theodore has received royalties from, holds stock ownership in, has consulted for, and has served on the scientific advisory board/other office for Globus Medical.<br /> (© Carly Weber-Levine et al., 2022; Published by Mary Ann Liebert, Inc.)
