title: Cell-cycle control during development: taking it up a notch.
abstract: The signals that coordinate cellular proliferation with G1 arrest and differentiation have long been of interest. Two papers in this issue of Developmental Cell show that the conserved Hedgehog and Notch signaling pathways regulate cell division during development of the Drosophila compound eye.
