PG - 109-119 LID - 10.1007/978-1-0716-2938-3_8 [doi] AB - Dendritic cells (DCs) comprise a heterogeneous population of antigen (Ag)-presenting cells that play a critical role in both innate and adaptive immunity. DCs orchestrate protective responses against pathogens and tumors while mediating tolerance to host tissues. Evolutionary conservation between species has allowed the successful use of murine models to identify and characterize DC types and functions relevant to human health. Among DCs, type 1 classical DCs (cDC1) are uniquely capable of inducing antitumor responses and therefore present a promising therapeutic target. However, the rarity of DCs, particularly cDC1, limits the number of cells that can be isolated for study. Despite significant effort, progress in the field has been hampered by inadequate methods to produce large quantities of functionally mature DCs in vitro. To overcome this challenge, we developed a culture system in which mouse primary bone marrow cells are cocultured with OP9 stromal cells expressing Notch ligand Delta-like 1 (OP9-DL1) to produce CD8alpha(+) DEC205(+) XCR1(+) cDC1 (Notch cDC1). This novel method provides a valuable tool to facilitate the generation of unlimited cDC1 for functional studies and translational applications such as antitumor vaccination and immunotherapy.
