The protocol was optimised for the preparation of PBMCs from human blood through using Ficoll-Hypaque density gradient centrifugation inaddition to using RPMI-10 complete medium (Gibco, United Kingdom) supplemented with penicillin/streptomycin (10 mg/ml), Glutamine (200 mM), 10% FCS, insulin and hydrocortisone.
In vitro culture and differentiation of human monocytes into dendritic cells DCs were achieved by using the Human Monocyte-derived Dendritic Cell Differentiation Kit (R&Dsystem, Minneapolis, MN, USA). This kit enables the generation of active mature DCs from human monocytes in 10 days (Amedei et al., 2011; Sabado and Bhardwaj, 2010).
