Treatment of Osteochondral Defects in the Rabbit's Knee Joint by Implantation of Allogeneic Mesenchymal Stem Cells in Fibrin Clots
1Department of Orthopaedic Sports Medicine, Klinikum rechts der Isar der Technischen Universität München, 2Department of Radiology, Klinikum rechts der Isar der Technischen Universität München, 3Institute of Experimental Oncology and Therapy Research, Klinikum rechts der Isar der Technischen Universität München, 4Department of Radiology, Uniklinik Köln
An experimental technique for the treatment of osteochondral defects in the rabbit's knee joint is described. The implantation of allogeneic mesenchymal stem cells into osteochondral defects provides a promising development in the field of tissue engineering. The preparation of fibrin-cell-clots in vitro offers a standardized method for implantation.

Matrix-assisted Autologous Chondrocyte Transplantation for Remodeling and Repair of Chondral Defects in a Rabbit Model
1Department of Orthopaedic Sports Medicine, Klinikum rechts der Isar der Technischen Universität München, 2Department of Radiology, Klinikum rechts der Isar der Technischen Universität München, 3Institute of Experimental Oncology and Therapy Research, Klinikum rechts der Isar der Technischen Universität München, 4Department of Radiology, Uniklinik Köln
An experimental technique for the treatment of chondral defects in the rabbit's knee joint is described. The implantation of autologous chondrocytes seeded on a matrix is a well-accepted method for the remodeling and repair of articular cartilage lesions providing satisfying long-term results. Matrix-assisted autologous chondrocyte transplantation (MACT) offers a standardized and clinically established implantation method.

In vitro Organoid Culture of Primary Mouse Colon Tumors
1Department of Molecular & Integrative Physiology, University of Michigan, 2Department of Internal Medicine, Division of Gastroenterology, University of Michigan
A simple method to establish primary murine colon tumor organoid is described. This method utilizes the feature that colon tumor cells survive and grow into organoids in media containing limited growth factors, whereas normal colon epithelial do not.

Mouse Models for Graft Arteriosclerosis
1Department of Surgery, Yale University School of Medicine, 2Department of Pathology, Yale University School of Medicine
We describe protocols for our mouse graft arteriosclerois (GA) models which involve interposition of a mouse vessel segment into a recipient of the same inbred strain. By backcrossing additional genetic changes into the vessel donor, the model can assess the effect of specific genes on GA.

A Murine Model of Stent Implantation in the Carotid Artery for the Study of Restenosis
1Institute for Molecular Cardiovascular Research, RWTH Aachen University, 2Institute for Textile Technology and Mechanical Engineering, RWTH Aachen University, 3Institute for Applied Medical Engineering, Helmholtz-Institute of RWTH Aachen University, 4Department of Experimental Molecular Imaging, RWTH Aachen University, 5Department of Oral and Maxillofacila Surgery, RWTH Aachen University
A model of stent implantation in mouse carotid artery is described. Compared to other similar methods, this procedure is very rapid, simple and accessible, offering the possibility to study in a convenient way the vascular wall reaction to different drug-eluting stents and the molecular mechanisms of restenosis.

Controlled Cervical Laceration Injury in Mice
1Norton Neuroscience Institute, Norton Healthcare, 2Spinal Cord and Brain Injury Research Group, Stark Neurosciences Research Institute, Department of Neurological Surgery and Goodman and Campbell Brain and Spine, Medical Neuroscience Graduate Program, and Department of Anatomy and Cell Biology, Indiana University School of Medicine
A novel technique to create a reproducible in vivo model of cervical spinal cord laceration injury in the mouse is described. This technique is based on spine stabilization by fixation of the cervical facets and laceration of the spinal cord using an oscillating blade with an accuracy of ±0.01 mm.

Bilateral Common Carotid Artery Occlusion as an Adequate Preconditioning Stimulus to Induce Early Ischemic Tolerance to Focal Cerebral Ischemia
Department of Neurology, Center for Stroke Research Berlin, Charité - Universitätsmedizin Berlin, Germany
There is accumulating evidence, that ischemic preconditioning (PC) – a non-damaging ischemic challenge to the brain - confers a transient protection to a subsequent damaging ischemic insult. We established bilateral common carotid artery occlusion (BCCAO) as a preconditioning stimulus to induce early ischemic tolerance (IT) to transient focal cerebral ischemia (induced by middle cerebral artery occlusion, MCAO) in C57Bl6/J mice.

Three-dimensional Imaging of Nociceptive Intraepidermal Nerve Fibers in Human Skin Biopsies
1Department of Neurology, University of Michigan, 2Department of Internal Medicine, University of Michigan
In order to study the changes of nociceptive intraepidermal nerve fibers (IENFs) in painful neuropathies (PN), we developed protocols that could directly examine three-dimensional morphological changes observed in nociceptive IENFs. Three-dimensional analysis of IENFs has the potential to evaluate the morphological changes of IENF in PN.

Measuring Cardiac Autonomic Nervous System (ANS) Activity in Children
1Department of Public Health, Academic Medical Center - University of Amsterdam, 2Department of Epidemiology, Documentation and Health Promotion, Public Health Service of Amsterdam (GGD), 3Department of Biological Psychology, VU University, 4EMGO+ Institute, VU University Medical Center, 5Institute of Health Sciences, VU University, 6Department of Pediatrics, VU University Medical Center
Measurement of autonomic nervous system activity usually confines the researcher and participant to the laboratory, which may provide an intimidating environment to children. The VU University Ambulatory Monitoring System (VU-AMS) device can record cardiac autonomic control in any setting. The VU-AMS proved very amenable to testing in children.

Non-invasive Imaging of Acute Allograft Rejection after Rat Renal Transplantation Using 18F-FDG PET
1Department of Internal Medicine D, Experimental Nephrology, University of Münster, 2Department of Nuclear Medicine, University of Münster, 3European Institute for Molecular Imaging, University of Münster
We herein present a rat renal transplantation model to non-invasively assess acute allograft rejection using positron emission tomography with 18F-fluorodeoxyglucose.
