The purpose of this study was to develop a monoclonal antibody (mAb) that can identify porcine dendritic cells (DCs) that have differentiated from bone marrow progenitor cells. Hybridoma technology was used to obtain mAbs, and bone marrow-derived DCs (BMDCs) were employed as immunogens for producing antibodies. The generated PD9-9 mAbs exhibited considerable reactivity towards porcine BMDCs with applications in flow cytometry and immunostaining. The antibody was composed of heavy immunoglobulin gamma-1 chains and light kappa chains. The PD9-9 mAb recognized fully differentiated porcine BMDCs and cells undergoing DC differentiation. In contrast, bone marrow cells and macrophages were not recognized by PD9-9. In addition, the PD9-9 mAb promoted porcine DC proliferation. Consequently, the PD9-9 mAb may be a biomarker for porcine DCs and will be advantageous for investigating porcine DC biology.
