Source: Lu, Y., et al. In Vitro Differentiation of Mouse Granulocyte-macrophage-colony-stimulating Factor (GM-CSF)-producing T Helper (THGM) Cells. J. Vis. Exp. (2018).
This video demonstrates the in vitro differentiation of granulocyte-macrophage-colony-stimulating factor or GM-CSF-producing T helper cells (THGM). Isolated naïve T cells are stimulated for differentiation into THGM, which is confirmed by detecting high intracellular GM-CSF production and a low expression of other T helper cell-specific cytokines.
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board.

2. Preparation of Murine Splenocytes
3. Isolation of CD4+ T Cells Using Magnetic CD4 Microbeads and a Cell Separation Column
4. Purification of the Naive CD4+ T cells (CD4+CD25–CD44loCD62Lhi) by Fluorescence-activated Cell Sorting and THGM differentiation
5. Analysis of the Mouse THGM Cells Generated In Vitro
