Abstract

This protocol will be useful to introduce the genes of interest into the cerebellar granule cells at early stages of development. Since the granule cell precursors are localized in the external granule layer before migration, DNA plasmids can be specifically incorporated into the granule cells by injecting DNA solution into the cerebellar fissures followed by application of electric pulses. This technique can be performed prior to the preparation of either dissociated or organotypic culture, which can be used to study the molecular mechanisms of cell migration, axon elongation and synapstogenesis during development.
