A major unsolved question in cortical development is how proliferation, neurogenesis, regional growth, regional identity, and laminar fate specification are coordinated. Here we provide evidence, using loss-of-function and gain-of-function manipulations, that the COUP-TFI orphan nuclear receptor promotes ventral cortical fate, promotes cell cycle exit and neural differentiation, regulates the balance of early- and late-born neurons, and regulates the balanced production of different types of layer V cortical projection neurons. We suggest that COUP-TFI controls these processes by repressing Mapk/Erk, Akt, and β-catenin signaling.

Key Words: β-catenin • COUP-TFI • Mapk/Erk • neurogenesis • PI3K/Akt • proliferation
