Our mission is to provide infrastructure and opportunities for international collaboration, to train young scientists, and to build new frontiers of life sciences. Heart regeneration is restricted to the first week after birth in mice, and the underlying molecular mechanisms remain poorly understood. The stages, and their names, are based on morphological features, generally readily identified by examination of the live embryo with the dissecting stereomicroscope.
