Generation of Immature, Mature, and Tolerogenic Dendritic Cells from Monocytes

Abstract

Source: Sim, W. J. et al., Generation of Immature, Mature and Tolerogenic Dendritic Cells with Differing Metabolic Phenotypes. J. Vis. Exp. (2016).

This video demonstrates the generation of immature, mature, and tolerogenic dendritic cells, or DCs, from human monocytes. The incubation of monocytes with growth factors and cytokines leads to the production of immature DCs. In response to immune regulatory molecules, immature DCs differentiate into tolerogenic and mature DCs.

Protocol

All procedures involving human participants have been performed in compliance with the institutional, national, and international guidelines for human welfare and have been reviewed by the local institutional review board. 1. Isolation of Peripheral Blood Mononuclear Cells (PBMCs)  Preparation of Reagent Prepare PBS/EDTA: phosphate-buffered saline solution (PBS) and supplement with 2 mM ethylenediaminetetraacetic acid (EDTA). Sterilize this solutio…
