In this study, to understand the correlation between C‐X‐C motif chemokine ligand 14 (CXCL14) in bone marrow dendritic cells (BMDCs) and antigen presentation of asthma dendritic cells (DCs), an in vitro model of BMDCs was constructed for RNA sequencing (RNA‐seq). The gene discussed is CXCL14; the disease is asthma.
