Antibody-secreting cells (ASC) such as plasma cells must migrate to the bone marrow to survive, but microniche elements that promote survival are unknown. Here the authors define specific factors from the microniche that can maintain ASC in vitro for over 50 days, involving MSC secretome proteins, APRIL, and hypoxic conditions.
