WebNov 29, 2024 · Long studied in Drosophila and insect gametogenesis, female germline cysts acquire cytoskeletal polarity and traffic centrosomes and organelles between nurse cells … WebAbstract. In Drosophila ovary, germline stem cells (GSCs) divide to produce two daughter cells. One daughter is maintained as a GSC, whereas the other initiates cyst formation, a process involving four synchronous mitotic divisions that form 2-, 4-, 8-, and 16-cell cysts. In this study, we found that reduction in the level of NHP2, a component ...
