Lymph nodes are strategically located throughout the body to allow lymphocytes to efficiently encounter their cognate antigen and become activated. The structure of the lymph nodes is such that B and T lymphocytes each have their own microdomain. This structure is provided by lymph node stromal cells, which also provide the lymphocytes with a scaffold upon which to migrate. Here, we discuss how stromal cells differentiate from mesenchymal precursor cells in response to the interaction with lymphocytes, while these stromal cells in turn provide necessary survival factors for the lymphocytes. We propose that during immune reactions, the interactions of stromal and immune cells are similarly important for controlling the expanding lymphocyte pool.
