title: Contrasting mechanisms of stem cell maintenance in Drosophila.
abstract: Stem cells are self-renewing multipotent cells essential for development or homeostasis of many tissues. Stem cell populations can be found in most multicellular plants and animals. The mechanisms by which these populations are maintained are diverse, utilizing both intrinsic and extrinsic factors to regulate cell division and differentiation. The genetic tools of the fruitfly, Drosophila melanogaster, have permitted detailed characterization of two stem cell populations. In this review, we will examine these contrasting stem cell model systems from Drosophila and their relevance to stem cell populations in other organisms.
