title: Running rings around chromosomes to trim axons and target dendrites.
abstract: The cohesin protein complex holds sister chromatids together to ensure proper chromosome segregation at mitosis in dividing cells. New experiments by two laboratories (reviewed in this issue of Developmental Cell) using different techniques reveal that cohesin also plays critical roles in morphogenesis of nondividing neurons. Other recent studies argue that these roles involve regulation of gene transcription.
