The Center for Genomic Pathology (CGP) is a non-profit organization dedicated to education and training of scientists and their staff in the pathology of genetically engineered mice (GEM) models. Our mission is to provide appropriate techniques for collection, integration, and presentation of pathology data. Our aim is to train the next generation of comparative pathologists in the use of GEM models. An impressive faculty of 40 internationally-recognized veterinary and human pathologists has been assembled to share expertise and prepare course material for global online presentation to researchers, staff and students. Our online courses are produced in cooperation with University of California, Davis Extension Distance Learning Group. Currently, three courses covering many aspects of Pathobiology of the Mouse are offered. Over 200 students from the US and 12 other countries have successfully completed these large courses while earning UC credits. Our courses include audio, text, video, still images, whole slide images and bibliographies. The classes begin at a basic level and progress to more advanced levels. A course sample can be viewed online. The first two courses have won The University Continuing Education Association's Community of Practice Award as the "Outstanding Course in Distance Learning" for 2010 and 2012 and a 2012 UC Davis Distinguished Service Award. Our recently released Tier II course materials are designed for more advanced students. The courses include didactic material and weekly online discussions with the instructor. This course is in-depth with advanced material on the GEM models for human mammary cancer study. Additional advanced courses on GEM models for other organ systems such as human prostate cancer evalluation are expected to be released early in 2013. The CGP and UC Davis Extension also have produced short courses on Pathobiology of the Mouse for CME Credit. CGP is currently offering franchise courses to interested institutions that meet underserved needs in pathobiology.
