While human MBCs are traditionally measured using blood, there is a growing interest in elucidating their behavior within lymphoid tissues, which are the main sites where adaptive immune responses are orchestrated. In this chapter, we introduce a high-throughput organoid system that is derived from primary human lymphoid tissues. The approach can recapitulate many hallmarks of successful adaptive immune responses and capture inter-individual variation in response to a variety of stimuli. Lymphoid tissue organoids enable characterization of pre-existing antigen-specific MBCs within an entirely human system and can provide valuable insights into MBC dynamics.
