The people behind the papers – James O'Sullivan and Zoë Mann

To build a functional inner ear, hair cell morphology must be precisely controlled along the proximo-distal axis. A new paper in Development shows that differential mitochondrial dynamics in proximal versus distal cells impacts on the apical cell surface area - a key aspect of morphology. To find out more about this work, we spoke to first author James O'Sullivan and senior author Zoë Mann, both at King's College London, UK.
