The people behind the papers - Caroline Johnson and Troy Ghashghaei.

Cortical development involves a switch from the self-amplification of stem cells to the generation of neuron and glia by progenitors. A new paper in Development investigates the molecular control of mitosis in these two stages, using simultaneous labelling and gene knockout in clones in the developing mouse brain. We caught up the paper's two authors Caroline Johnson and her supervisor Troy Ghashghaei, Professor of Neurobiology at the College of Veterinary Medicine at North Carolina State University, to find out more.
