Study Design:
Review.
Objectives:
To highlight the value of investigating the effects of putative therapeutic interventions in clinical spinal cord injury (SCI) in domestic dogs.
Setting:
England, UK.
Methods:
Many experimental interventions in laboratory rodents have been shown to ameliorate the functional deficits caused by SCI; the challenge now is to determine whether they can be translated into useful clinical techniques. Important differences between clinical SCI in human patients and that in laboratory rodents are in the size of the spinal cord and heterogeneity of injury severity. A further key issue is whether the statistical difference in outcome in the laboratory will translate into a useful difference in clinical outcome. Here, we stress the value of investigating the effects of putative therapies in clinical SCI in domestic dogs. The causes of injury, ability to categorise the severity and methods available to measure outcome are very similar between canine and human patients. Furthermore, postmortem tissue more rapidly becomes available from dogs because of their short lifespan than from human patients.
Results:
The role that investigation of canine SCI might play is illustrated by our preliminary trials on intraspinal transplantation of olfactory glial cells for severe SCI.
Conclusions:
This canine translational model provides a means of 'filtering' putative treatments before human application.
Insights
Investigating therapeutic interventions in dogs with spinal cord injury (SCI) offers a valuable translational model. This approach helps filter potential treatments before human application, improving clinical outcomes.
Area of Science:
- Comparative medicine
- Translational research in neurotrauma
Background:
- Experimental therapies for spinal cord injury (SCI) in rodents show promise but face translation challenges.
- Key differences between rodent models and human SCI include spinal cord size and injury heterogeneity.
- Statistical significance in rodent studies may not equate to clinically meaningful outcomes in humans.
Purpose of the Study:
- To emphasize the utility of studying therapeutic interventions for clinical SCI in domestic dogs.
- To highlight the domestic dog as a suitable translational model for SCI research.
Main Methods:
- Review of existing research and proposed translational approach.
- Focus on domestic dogs as a model due to similarities with human SCI (injury causes, severity assessment, outcome measures).
- Utilizing the rapid availability of postmortem tissue from dogs.
Main Results:
- Preliminary trials involving intraspinal transplantation of olfactory glial cells for severe SCI in dogs are presented.
- These trials illustrate the potential role of canine SCI investigation.
Conclusions:
- The domestic canine serves as an effective translational model for filtering potential SCI treatments.
- This model facilitates the evaluation of therapies prior to human clinical trials, enhancing treatment efficacy.
