Haley VA Medical Center, 6Shriners Hospital for Children, 7Savaria Department of Biology, ELTE Eötvös Loránd University Here, we present a protocol to investigate changes in the anxiety level of rodent animal models. The elevated plus maze (EPM) test, used together with a video tracking software, provides a reliable method to document the effect of various potential anxiolytic treatments in preclinical laboratory scenarios. Medicine Calibrated Forceps Model of Spinal Cord Compression Injury Ashley McDonough*1,2, Angela Monterrubio*1,2, Jeanelle Ariza1,2, Verónica Martínez-Cerdeño1,2 1Department of Pathology and Laboratory Medicine, University of California, Davis, 2Institute for Pediatric Regenerative Medicine, Shriners Hospitals for Children (Northern California) Spinal cord injury models should be highly reproducible. We demonstrate that the calibrated forceps compression model of spinal cord injury is an easy to use surgical method for generating reproducible injuries to the murine spinal cord.

Here, a novel gene transfer technique for differentiation of osteoclasts in vivo and cell culture protocols for differentiating precursor cells into osteoclasts in vitro as a method to study the effects of cytokines on osteoclastogenesis are described.
