Figure 2. (A) Fetal Thymic Organ Culture analysis of WT and Itk−/− thymocyte development.

Figure 2

FTOC from embryonic day 16 of WT and Itk null mice incubated in vitro for the indicated days, gated on TCRhi and analyzed for CD4 and CD8 (data representative of 3–4 mice). (B) Active Itk kinase activity is required for T cell development. Thymocytes from WT, Itk−/−, Tg(Lck-ItkΔKin)Itk−/− and Tg(CD2-Itktg)Itk−/− mice were gated first on the TCRhi and analyzed for expression of CD4 and CD8.
