Abstract
Transplantation in mouse brain slices is a powerful tool in order to study axon targeting and migrational events during development. Taking advantage of donors and recipients belonging to different genotypes, this technique allows researchers to assess the contribution of donor and/or recipient tissue by performing various combinations and to study cell-autonomous functions or effects that are influenced by the recipient’s environment (Bastakis, et al., 2015). Here we describe the transplantation procedure on sagittal brain slices containing olfactory bulb (OB). Specifically, we have transplanted the proximal-to-the-cortex part of dorsal OB to the same region on a recipient slice. Transplanted slices can be cultured for up to 3 days before their morphology is disfigured due to growth in 3D. Re-sectioning of these slices allows for a more detailed immunohistochemical analysis.
