• Involves validated and straightforward procedures

• Does not require specialized instrumentation

Why Differentiate Treg Cells In Vitro?

Forkhead Box P3 (FoxP3)⁺ regulatory T (Treg) cells are a suppressive subset of CD4⁺ T cells that function to antagonize immune responses. Treg cells have the capacity to prevent potentially damaging autoimmune and protective immune responses, so the number of Treg cells is a crucial determinant of the regulatory burden on the immune system. In vitro differentiation of Treg cells from the larger naïve CD4⁺ T cell population provides increased numbers of Treg cells to facilitate downstream research.
