A comprehensive understanding of the cell biology of adult neural stem cells (aNSCNSCNSCs) requires direct observation of aNSCNSCNSC division and lineage progression in the absence of niche-dependent signals. Here we describe a culture preparation of the adult mouse subependymal zone (SESEZ), which allows for continuous single-cell tracking of aNSCNSCNSC behavior. The protocol involves the isolation (~3 h) and culture of cells from the adult SESEZ at low density in the absence of mitogenic growth factors in chemically defined medium and subsequent live imaging using time-lapse video microscopy (5–7 d); these steps are followed by postimaging immunocytochemistry to identify progeny (~7 h). This protocol enables the observation of the progression from slow-dividing aNSCNSCNSCs of radial/astroglial identity up to the neuroblast stage, involving asymmetric and symmetric cell divisions of distinct fast-dividing precursors. This culture provides an experimental system for studying instructive or permissive effects of signal molecules on aNSCNSCNSC modes of cell division and lineage progression.
