Upon engagement in an immune response, a naive T lymphocyte undergoes a program of rapid proliferation and many of its cellular progeny undergo terminal effector differentiation. After an immune response has ended, some antigen-specific daughter cells remain as long-lived replicas of the useful clone, so-called memory cells, which form the basis for successful vaccination. Using lymphocytes as a model system, we have provided evidence that asymmetric cell division may be a way for many mobile, non-polarized cells to generate cell fate diversity among their progeny. We are using static and time-lapsed imaging, genetic, and biochemical methods to better understand the nature and extent of asymmetric cell division in multi-celled beings. It is predicted that this will have immediate relevance for the way in which blood stem cells and metastatic cancer stem cells can generate diverse progeny despite their lack of obvious polarity. Studies of lymphocyte differentiation during the immune response should continue to become an increasingly useful model for inquiry into the fundamental problem of regulated gene expression in dividing, differentiating, and highly mobile cells.
