Why Differentiate Th17 Cells In Vitro?
T helper type 17 (Th17) cells are a subset of CD4+ effector T cells that promote cell-mediated immune responses against extracellular bacteria and fungi. Differentiation into the Th17 lineage is promoted by cytokines such as TGF-beta and IL-6, while their survival and expansion are dependent on IL-21 and IL-23. Th17 cells secrete TNF-alpha, IL-6, IL-9, IL-17A, IL-17F, IL-21, IL-22, and (human) IL-26/AK155. Th17 polarized cells are present in low abundance in normal human peripheral blood. In vitro differentiation of Th17 cells from the larger naïve CD4+ T cell population provides increased numbers of Th17 cells to facilitate downstream research.
This kit contains the following optimized proteins and reagents to drive efficient differentiation of naïve CD4+ T cells into Th17 polarized cells.
- Mouse Anti-Human CD3 Antibody
- Mouse Anti-Human CD28 Antibody
- Human Th17 Reagent 1
- Human Th17 Reagent 2
- Human Th17 Reagent 3
- Human Th17 Reagent 4
- Human Th17 Reagent 5
- Reconstitution Buffer 1
- Reconstitution Buffer 2
- Reconstitution Buffer 3
- 20X Wash Buffer
The quantity of the components in the kit is sufficient to differentiate one 24-well plate, or approximately 2.5-5 x 106 naïve CD4+ T cells, and generate a 20-fold increase of Th17 polarized cells within your starting CD4+ T cell population.
Stability and Storage
Store the unopened kit at 2 to 8 °C. After opening the kit, Mouse Anti-Human CD3 Antibody, Mouse Anti-Human CD28 Antibody, and Human Th17 Reagents 1-5 can be stored at 2-8 °C under sterile conditions for up to 30 days or at -20 °C to -70 °C in a manual defrost freezer for up to 3 months. Reconstitution Buffer 1, Reconstitution Buffer 2, Reconstitution Buffer 3, and 20X Wash Buffer may be stored under sterile conditions for up to 3 months at 2 to 8 °C. Do not use beyond the expiration date of the kit.

Intracellular Cytokine Staining of Differentiated Human Th17 Cells. Flow cytometry data showing human peripheral blood naïve CD4+ T cells without (A, C) and with (B, D) a 10-day differentiation using reagents included in this kit. On day 10 of differentiation, the cells were stimulated with Cell Activation Cocktail (Tocris®, Catalog # 5476) and stained with APC-conjugated Mouse Anti-Human IL-17 Monoclonal Antibody (Catalog # IC317A), PE-conjugated Mouse Anti-Human IFN-gamma Monoclonal Antibody (Catalog # IC285P) and a Fluorescein-conjugated Mouse Anti-Human IL-4 Monoclonal Antibody (Catalog # IC204F). Quadrants were placed based on isotype control-stained samples. |

Th17-differentiated Human CD4+ Cells Secrete IL-17. Human peripheral blood naïve CD4+ T cells were differentiated for 10 days under Th17 polarization conditions using reagents included in this kit. On day 10, cell culture supernatant was collected and cytokine expression was determined using the Human IL-17 Quantikine® ELISA Kit (Catalog # D1700), the Human IFN-gamma Quantikine® ELISA Kit (Catalog # DIF50), and the Human IL-4 Quantikine® ELISA Kit (Catalog # D4050). |

R&D Systems Protocol for human Th2 cell differentiation
Coat wells of a 24-well plate with Mouse Anti-Human CD3 Antibody.
Isolate PBMCs from human blood.
Isolate human naïve CD4+ T cells from PBMCs (e.g., using magnetic cell selection).
Perform a cell count.
Suspend 1-2 x 105 naïve CD4+ T cells/mL in Human Th17 Cell Differentiation Media
