Reproducible Mouse Sciatic Nerve Crush and Subsequent Assessment of Regeneration by Whole Mount Muscle Analysis
Center for Neural Repair and Rehabilitation, Temple University
In this report we describe a method to crush mouse sciatic nerve. This method uses readily available hemostatic forceps and easily and reproducibly produces complete sciatic nerve crush. In addition, we describe a method to prepare muscle whole mounts suitable for analysis of nerve regeneration after sciatic nerve crush.
Chromatin Immunoprecipitation from Dorsal Root Ganglia Tissue following Axonal Injury
1Laboratory for NeuroRegeneration and Repair, Department of Neurology, Hertie Institute for Clinical Brain Research, University of Tuebingen , 2Graduate School for Cellular and Molecular Neuroscience, University of Tuebingen
We present a method for chromatin immunoprecipitation from dorsal root ganglia tissue following axonal injury. The approach can be used to identify specific transcription factor binding sites and epigenetic modification of histone and DNA important for the regeneration of injured axons in both the peripheral and central nervous system.
Axoplasm Isolation from Rat Sciatic Nerve
Department of Biological Chemistry, Weizmann Institute of Science
We demonstrate a protocol for axoplasm isolation from adult rat sciatic nerve based on dissection of nerve fascicles and incubation in hypotonic medium to release myelin and lyse non-axonal structures, followed by extraction of the remaining axon-enriched material.
Chronic Constriction of the Sciatic Nerve and Pain Hypersensitivity Testing in Rats
School of Medical Sciences, University of New South Wales
Due to the simplicity of surgery and the robust behavioural outcome, chronic constriction of the sciatic nerve is one of the pre-eminent animal models of neuropathic pain. Within 24 hrs following surgery, pain hypersensitivity is established and can be quantitatively measured using a von Frey aesthesiometer (mechanical test) and plantar analgesia meter (thermal test).
The Spared Nerve Injury (SNI) Model of Induced Mechanical Allodynia in Mice
1The Lundbeck Foundation Research Center MIND, Department of Biomedicine, Aarhus University, 2Department of Pharmacology and Pharmacotherapy, Faculty of Pharmaceutical Sciences, University of Copenhagen
The Spared Nerve Injury animal model is described here as a mouse model of peripheral neuropathic pain following partial denervation of the sciatic nerve by lesioning the tibial and common peroneal nerve branches, leaving the remaining sural nerve intact. Behavioral modification resulting from mechanical allodynia is quantified by von Frey filaments.
An Optic Nerve Crush Injury Murine Model to Study Retinal Ganglion Cell Survival
1National Eye Institute, NIH, 2Ophthalmology Department, The Second Hospital of Harbin Medical University
This protocol shows how to retrogradely label retinal ganglion cells, and how to subsequently make an optic nerve crush injury in order to analyze retinal ganglion cell survival and apoptosis. It is an experimental disease model for different types of optic neuropathy, including glaucoma.
Procedures for Rat in situ Skeletal Muscle Contractile Properties
Faculty of Kinesiology, University of Calgary
This video demonstrates the surgical preparation and procedures needed to study the contractile responses of the rat medial gastrocnemius muscle preparation in situ. This preparation allows measurement of skeletal muscle contractile properties under physiological conditions. The animal is anesthetized and the muscle is separated from surrounding tissue at its distal end. The Achilles tendon is attached to a force transducer, allowing measurement of the muscle’s contractile response at 37 degrees C with an intact circulation.
Orthotopic Xenografting of Human Luciferase-Tagged Malignant Peripheral Nerve Sheath Tumor Cells for in vivo Testing of Candidate Therapeutic Agents
1Department of Pathology, University of Alabama at Birmingham - UAB, 2Department of Radiology, University of Alabama at Birmingham - UAB, 3Department of Cell Biology and Neurobiology, University of Alabama at Birmingham - UAB
A method for reliably grafting luciferase-tagged human malignant peripheral nerve sheath tumor cells into the sciatic nerve of immunodeficient mice is described. The use of bioluminescence imaging to demonstrate proper establishment of tumor grafts and criteria for random segregation of animals into study groups are also discussed.
Modeling Biological Membranes with Circuit Boards and Measuring Electrical Signals in Axons: Student Laboratory Exercises
1Department of Biology, University of Kentucky, 2Department of Physiology, University of Toronto
This is a demonstration of how biological membranes can be understood using electrical models. We also demonstrate procedures for recording action potentials from the ventral nerve cord of the crayfish for student orientated laboratories.
Combining Peripheral Nerve Grafting and Matrix Modulation to Repair the Injured Rat Spinal Cord
Department of Neurobiology and Anatomy, Drexel University College of Medicine
Traumatic injury to the spinal cord disrupts communication with the brain. To restore lost connectivity we utilize a peripheral nerve graft to provide a substratum for regenerating fibers in combination with neurotrophic factors and matrix-modulating enzymes to remove inhibitory molecules to promote long distance growth.
