Mother Centrioles Do a Cartwheel to Produce Just One Daughter

摘要

In this issue of Developmental Cell, Fong et al. (2014) present evidence for a model of centriole duplication whereby the cartwheel-the starting building block in centriole biogenesis-assembles within the lumen of the mother centriole before templating the daughter centriole to ensure a single duplication event per cell cycle.
