Taking a break helps drosophila germline cells reach their destination

(University of Tsukuba) Quiescence, or breaks during cell cycling, are common during germ cell development in many animals but the mechanisms regulating these periods are unclear. In a recent study from the University of Tsukuba, researchers identified a microRNA, miR-10404, and subsequently the entire pathway, governing the first of two quiescence periods in Drosophila germ-cell cycling. Understanding this mechanism furthers our understanding of the significance of quiescence in germline develo...
