Why Generate Monocyte-derived Dendritic Cells Ex Vivo?
Dendritic cells are a heterogeneous population of functionally homologous immune cells that act as key mediators of the innate and adaptive immune responses. Under homeostatic conditions, dendritic cells are present in large numbers in areas of intense antigen exposure such as the skin, lung, and intestine and can be difficult to isolate and harvest. However, in response to an immune stimulus, CD14+ monocytes, which are present in high numbers in the periphery and circulation, can differentiate into inflammatory/monocyte-derived dendritic cells. Harvesting CD14+ monocytes from peripheral blood mononuclear cells and driving their differentiation into either immature or mature dendritic cells provides an abundant source of monocyte-derived dendritic cells for downstream studies.
This kit contains the following optimized reagents for the differentiation of monocyte-derived dendritic cells.
- Serum-Free Dendritic Cell Base Media
- Recombinant Human IL-4
- Recombinant Human GM-CSF
- Recombinant Human TNF-alpha
- Reconstitution Buffer 2

Morphology of Immature Human Dendritic Cells Cultured in Differentiation Media for 7 days. Human CD14+monocytes were differentiated into immature human dendritic cells by culturing for 7 days using reagents included in this kit. Immature dendritic cells exhibit characteristic dendritic cell morphology.

Phenotypic Analysis of Cultured Immature and Mature Monocyte-derived Dendritic Cells. Following culture in complete monocyte-derived differentiation media provided in this kit, day 7 immature dendritic cells (top) and day 10 TNF-alpha treated mature dendritic cells (bottom) were stained with the indicated antibodies for DC-SIGN/CD209 (Catalog # MAB161), B7-1/CD80 (Catalog # MAB140), B7-2/CD86 (Catalog # MAB141), CD83 (Catalog # MAB1774; open histograms), or an appropriate isotype control antibody (filled histograms). Stained cells were analyzed using a Becton Dickinson FACSCalibur™.

Mature Dendritic Cells Induce Proliferation of Allogeneic T-cells. Serial dilutions of day 10 TNF-alpha treated mature dendritic cells were incubated with allogeneic (blue) or autologous (red) human T cells for 3 days.3H-Thymidine (3H-TdR) was added to the culture for the final 18 hours. Cells were harvested and the incorporation of3H-TdR was measured using a scintillation counter. Results are presented as the mean cpm of triplicates.
Assay Procedure
Refer to the product datasheet for complete product details.
Briefly, mature human monocyte-derived dendritic cells can be generated using the following procedure:

FAQs
-
What method should be used for dissociation of cells in CellXVivo Human Monocyte-derived DC Differentiation Kit, Catalog # CDK004?
Cell scraping is prefered but dissociation in 2 mM EDTA can be used as an alternative method.
-
For CellXVivo Human Monocyte-derived DC Differentiation Kit, Catalog # CDK004, are the dendritic cells harvested on day 7 and day 10 adherent or in suspension?
When using Catalog # CDK004, the dendritic cells harvested on day 7 and day 10 are a mixture of cells in suspension and adherent cells. Typically ~50-90% of the cells are in suspension at day 7 and ~40-80% of the cells are suspension at day 10.
-
The Cloudz NK Cell Expansion protocol, Catalog # CDL004, recommends using T25 flasks. Do you have a protocol or recommended starting cell numbers for larger flasks, such as T75?
It is important to maintain a higher density of cells in the beginning of the culture, so start in a T25 and then scale up to a T75/T175 after 6-9 days when the cells are expanding exponentially. The cells expand dramatically at some point between day 6-9, dependent on donor.
-
Can dendritic cells be split after day 7 when following the protocol in Catalog # CDK004, CellXVivo Human Monocyte-derived DC Differentiation Kit?
Cells obtained on day 7 using Catalog # CDK004 kit are immature dendritic cells. If the desired application calls for immature dendritic cells, day 7 cells can be used. However, if mature dentritic cells are needed, the maturation protocol should be continued preferably in the same plate and cells should not be split at this stage.
