Funds are requested for partial support of U.S.-based scientists and students in the Americas to participate in the Short Course Concepts and Model Organisms in Regenerative Biology, to be held at Pontificia Universidad Cat[unreadable]lica de Chile in Santiago, Chile, November 2-11, 2010. This will be the third major collaborative training event between the Society for Developmental Biology (SDB) and the Latin American Society for Developmental Biology (LASDB) in Latin America, with the participation of distinguished scientists and top students from the United States (15) and Latin American countries (15). The first two short courses were held in spring of 2005 in Brazil and fall of 2008 in Argentina. This third course will be satellite to the LASDB's 5TH International Meeting, which will allow the students to attend andpotentials and limitations of the traditional and emerging technologies, as well as model organisms used in such studies. The practical sessions held in laboratories with state-of-the-art equipment will provide plenty opportunity for the students to acquire hands-on experience working with different organisms that have well-known as well as those with uncommon regenerative properties: mouse, frog, zebrafish, salamander, fly, roundworm, planarian, sea cucumber, and plant. Students will be selected from applications submitted by postdoctoral fellows and advanced graduate students in the U.S., and from graduate students, postdoctoral fellows, and young faculty in Latin America, based on their previous experience and interest in the field. Latin American faculty in other disciplines who are considering a change in the focus of their research to regenerative/developmental biology will also be eligible. Most
