Biology, Natural sciences A germ cell-specific organelle assembled from membrane skeletal proteins and membranous vesicles.
- Cystoblasts/cystocytes also divide asymmetrically, and in doing so, the spectrosome evolves into a branched fusome in the 16-cell cyst (5,37), accumulating proteins like Bam, ankyrin, α- and β-spectrins, the adducinlike product of the hu-li tai shao gene (HtsF), dynein (Dhc64C), and Cyclin A (5,35,36).2004, Daryl S. Henderson, Drosophila Cytogenetics Protocols, page 95:
- This demonstrates a key role of the fusome as a channel of communication between the cells for the synchronisation and differentiation of the germline cyst.2007, Alvaro Macieira-Coelho, Asymmetric Cell Division, page 105:
