How do the cells that secrete saliva or tears handle the load? 

The tips of two adult fruit fly testes, viewed under a confocal microscope, are filled with dividing germ cells (green). About one quarter of these germ cells die by an alternative death pathway called germ cell death (pink and red)

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)
