Microglia can expand and divide quickly in the context of CNS pathology, but little is known about the kinetics and clonality of microgliosis. Prinz and colleagues develop a new fate mapping system to monitor microglial dynamics. Microglial self-renewal is found to be a stochastic process under steady state conditions, whereas clonal expansion is observed during disease.
