Dendritic cells (DCs) are mononuclear phagocytes of hematopoietic origin residing in lymphoid and nonlymphoid tissues. DCs are often referred as the sentinels of the immune system as they can sense pathogens and danger signals. Upon activation, DCs migrate to the draining lymph nodes and present antigens to naïve T cells to trigger adaptive immunity. Hematopoietic progenitors for DCs reside in the adult bone marrow (BM). Therefore, BM cell culture systems have been developed to generate large amounts of primary DCs in vitro conveniently enabling to analyze their developmental and functional features. Here, we review various protocols enabling to generate DCs in vitro from murine BM cells and discuss the cellular heterogeneity of each culture system.
