Visualization of adult stem cells within their niches using the Drosophila germline as a model system.

The germaria of the fruit fly Drosophila melanogaster present an excellent model to study germline stem cell–niche interactions. Two to three adult stem cells are surrounded by a number of somatic cells that form the niche. Here we describe how Drosophilae germaria can be dissected and specifically immuno-stained to allow for identification and analysis of both the adult stem cells and their somatic niche cells
