Regional variations in the rate of neurogenesis have been observed along the dorsoventral axis of the rodent hippocampus1,2. Furthermore, the rates of hippocampal neurogenesis also show distinct inter-species variation, with precursor cell turnover in the subgranular zone shown to be significantly lower in adult humans than in rodents3-5. Inter-species differences in hippocampal structural anatomy may be relevant here, as it has been postulated that neural stem cell distribution along the murine ventricular neuraxis may be influenced by cephalic flexures during embryological development6. To date, the rodent brain remains the most popular system in which to study adult neurogenesis. However, the brain of the domestic dog (Canis familiaris), with a size and structural organization intermediate between that of humans and rodents7, represents a valuable yet highly underused animal model. The canine hippocampus in particular embodies this structurally intermediate nature8-10 and can provide a unique perspective on intrinsic variations in neural precursor cell populations. With many closer parallels to the human brain, the canine model may also offer insight into the biology of adult human neurogenesis.
In vitro culture assays have become a key tool for the study of neural precursors and the cellular and biomolecular processes of adult neurogenesis. The neurosphere assay and adherent monolayer culture represent the two predominant systems for expanding neural precursor cells in vitro11-13. Protocols for brain extraction, hippocampal microdissection or neural precursor culture assays have been well documented for the rodent model14-16. However, for the adult canine brain they remain comparatively few17,18, focused instead on fetal or neonatal tissue19-21.
In our published study7 we investigated regional variations in neurogenesis and neural precursor cell populations across the dorsoventral axis of the adult canine hippocampus. Although highly dependent on breed, adulthood in canines is reached between 1 and 3 years of age. Here, we present detailed methods for the extraction, isolation and culture of neural precursor cells from the canine hippocampus. We provide systematic protocols for the expansion of neural precursor cells as both floating neurospheres and as an adherent monolayer culture, and for their subsequent differentiation into mature neural cell types.

isolation and expansion of adult canine hippocampal neural precursors

The rate of neurogenesis within the adult hippocampus has been shown to vary across mammalian species. The canine hippocampus, demonstrating a structural intermediacy between the rodent and human hippocampi, is therefore a valuable model in which to study adult neurogenesis. In vitro culture assays are an essential component of characterizing neurogenesis and adult neural precursor cells, allowing for precise control over the cellular environment. To date however, culture protocols for canine cells remain under-represented in the literature. Detailed here are systematic protocols for the isolation and culture of hippocampal neural precursor cells from the adult canine brain. We demonstrate the expansion of canine neural precursor cells as floating neurospheres and as an adherent monolayer culture, producing stable cell lines that are able to differentiation into mature neural cell types in vitro. Adult canine neural precursors are an underused resource that may provide a more faithful analogue for the study of human neural precursors and the cellular mechanisms of adult neurogenesis.
