Why Expand and Differentiate Mouse Th1 and Th2 Cells Ex Vivo?
T helper type 1 (Th1) cells are a lineage of CD4+ effector T cells that promote cell-mediated immune responses against intracellular viral and bacterial pathogens. Enhanced Th1 responses are associated with autoimmune diseases including rheumatoid arthritis, multiple sclerosis, inflammatory bowel disease, and type-1 diabetes. Differentiation of CD4+ effector T cells into the Th1 lineage is promoted by cytokines such as IL-12 and IFN-gamma. Th1 cells secrete IFN-gamma, IL-10, and TNF-alpha. The CellXVivo™ Mouse Th1 Cell Differentiation Kit contains optimized reagents for Th1 differentiation from naïve CD4+ cells.
This kit contains the following reagents for the ex vivo differentiation of mouse Th1 cells.
- Hamster Anti-Mouse CD3, Th1
- Mouse Th1 Reagent 1
- Mouse Th1 Reagent 2
- Mouse Th1 Reagent 3
- Mouse Th1 Reagent 4
- Reconstitution Buffer 1
- Reconstitution Buffer 2
- 20X Wash Buffer
The quantity of components in this kit is sufficient to differentiate approximately 8 x 106 naïve CD4+ T cells, and generate 8 x 107 CD4+ cells of which 70-90% are IFN-gamma+ Th1 polarized cells.
Note: Results may vary due to strain, age, and/or the health of the mice used for isolation.

| Intracellular Cytokine Staining of Differentiated Mouse Th1 Cells. Flow cytometry data of mouse naïve CD4+ T cells (A, C) and differentiated Th1 cells (B, D) generated using reagents included in this kit. After 6 days of differentiation, naïve CD4+ cells or differentiated Th1 cells were stimulated with Cell Activation Cocktail (Tocris®, Catalog # ) and stained with conjugated Anti-Mouse IFN-gamma (R&D Systems, Catalog # ), Anti-Mouse IL-4 (Clone 11B11), and Anti-Mouse IL-17A (Novus Biologicals, Catalog # ) Monoclonal Antibodies. Quadrants were set based on isotype-stained controls. |
| Th1-differentiated Mouse CD4+ Cells Secrete High Levels of IFN-γ. Mouse naïve CD4+ T cells were differentiated for 6 days using the reagents included in this kit. On day 6 of differentiation cells were harvested and re-stimulated with Anti-Mouse CD3 and Anti-Mouse CD28 overnight. The cell culture supernatant was collected and cytokine secretion was determined using the Mouse IFN-gamma Quantikine® ELISA Kit (Catalog # ), the Mouse IL-4 Quantikine® ELISA Kit (Catalog # ), and the Mouse IL-17 Quantikine® ELISA Kit (Catalog # ). |
| Upregulation of T-bet, TNF-alpha, and IL-18R alpha in Th1-polarized Mouse CD4 Cells. Mouse CD4 cells were isolated and differentiated into Th1 cells using the CellXVivo™ Mouse Th1 Cell Differentiation Kit. Differentiated mouse Th1 cells (A, B, C) and naïve mouse CD4 cells (D, E, F) were analyzed by flow cytometry for (A, D) T-bet expression using Human T-bet/TBX21 Alexa Fluor® 488-conjugated Antibody (Catalog # ), (B, E) TNF-alpha expression using Mouse TNF-alpha PE-conjugated Antibody (Catalog # ), and (C, F) IL-18R alpha expression using Mouse IL-18 R alpha /IL-1 R5 APC-conjugated Antibody (Catalog # ). Cells were also gated on CD4 expression using the Mouse CD4 Alexa Fluor® 700-conjugated Antibody (Catalog # ). Differentiated mouse Th1 cells were stimulated with Cell Activation Cocktail (Tocris®, Catalog # ) for 4 hours prior to antibody staining. Quadrants were determined by naïve CD4 T cells expression levels. |
