A new method is helping to resolve controversies and answer some open questions in biology. 
The adult stem cell unit: Niches are in red. Cap cells (barbed arrowhead) are tightly associated with germ-line stem cells (outlined). Germ-line stem cells carry a spherical organelle - a fusome - which is asymmetrically localized to the side of the cap cells (arrow). Once the stem cell divides, one daughter cell loses contact with the niche and differentiates (green). The fusome in a differentiating germ cell becomes branched (arrowhead)
