The positioning and the cleavage plane orientation of mitotic cells in pseudostratified epithelia (PSE) must be tightly regulated since failures in any of these processes might have fatal consequences during development. Here we present a simple method to determine the spindle orientation as well as the positioning of neuroepithelial mitotic cells within the Outer Proliferation Center (OPC) of Drosophila larval brains.
