Background: During embryonic development cell migration plays a principal role in several processes. In past decades, many studies were performed to investigate migrational events, occurring during embryonic organogenesis, neurogenesis, gliogenesis or myogenesis, just to name a few. Although different common techniques are already used for this purpose, one of their major limitations is the static character. However, cell migration is a sophisticated and highly dynamic process, wherefore new appropriate technologies are required to investigate this event in all its complexity. Results and Conclusions: Here we report a novel approach for dynamic analysis of cell migration within embryonic tissue. We combine the modern transfection method of in ovo electroporation with the use of tissue slice culture and state-of-the-art imaging techniques, such as confocal laser scanning microscopy or spinning disc confocal microscopy, and thus, develop a method to study live the migration of myogenic precursors in chicken embryos. The conditions and parameters used in this study allow long-term imaging for up to 24 hr. Our protocol can be easily adapted for investigations of a variety of other migrational events and provides a novel conception for dynamic analysis of migration during embryonic development.
