Fusome

Fusome

Fusome (/ˈfjuːsəʊm/) is a cell organelle found in the germline cells of Drosophila and other insects. It plays a crucial role in oogenesis and spermatogenesis, the processes of egg and sperm production, respectively.

Etymology

The term "fusome" is derived from the Latin "fusus," meaning "spindle," and the Greek "soma," meaning "body." This reflects the fusome's spindle-like structure and its role in cell division.

Function

The fusome is involved in the distribution of chromosomes and cytoplasm during cell division. It also plays a role in the synchronization of mitosis in germline cysts, ensuring that all cells in a cyst divide at the same time.

Structure

The fusome is a branched structure that extends through the ring canals of germline cysts. It is composed of membrane skeleton proteins, including spectrin, ankyrin, and adducin, as well as lipids and proteins.
