title: Fly stem cell research gets infectious.
abstract: To maintain tissue homeostasis, stem cells need to increase their proliferation rate to repair tissue damage caused by stress or infection. In this issue, Jiang et al. (2009) describe a regulatory feedback mechanism involving the Jak/Stat signaling pathway that enables stem cells of the fly midgut to accomplish this task.
