This protocol is based on modifications of procedures that have been described in the past3,7,11. There are several important points to note as discussed below.
The granule neurons and progenitor cells adhere within 2 hours of plating. Healthy cells have a round morphology under the phase-contrast microscope4. Within 24 hours after plating, healthy cells will spread evenly around the coverslips or the plastic well and will form processes. At the time of the first medium ...

isolation and culture of post-natal mouse cerebellar granule neuron progenitor cells and neurons 

The cerebellar cortex is a well described structure that provides unique opportunities for studying neuronal properties and development1,2. Of the cerebellar neuronal types (granule cells, Purkinje cells and inhibitory interneurons), granule neurons are by far the most numerous and are the most abundant type of neurons in the mammalian brain. In rodents, cerebellar granule neurons are generated during the first two post-natal weeks from progenitor cells in the outermost layer of the cerebellar cortex, the external granule layer (EGL). The protocol presented here describes techniques to enrich and culture granule neurons and their progenitor cells from post-natal mouse cerebellum. We will describe procedures to obtain cultures of increasing purity3,4, which can be used to study the differentiation of proliferating progenitor cells into granule neurons5,6. Once the progenitor cells differentiate, the cultures also provide a homogenous population of granule neurons for experimental manipulation and characterization of phenomena such as synaptogenesis, glutamate receptor function7, interaction with other purified cerebellar cells8,9 or cell death7.
