Thymocyte development in GIMAP1/CD2-cKO mice. (A) Representative FACS plots of thymocytes from GIMAP1^fl/flhCD2-iCre⁻ and GIMAP1^fl/flhCD2-iCre⁺ mice stained for CD4, CD8, and TCR (the latter to exclude CD8⁺ intermediate SP cells). (B) Mean numbers (± SD) of thymocyte subsets (■ indicates GIMAP1^fl/flhCD2-iCre⁻, n = 22; □, GIMAP1^fl/flhCD2-iCre⁺, n = 18). (C) Mean numbers (± SD) of mature (Qa2^hiCD24⁻) CD4 and CD8 SP thymocytes (■ indicates GIMAP1^fl/flhCD2-iCre⁻, n = 6; □, GIMAP1^fl/flhCD2-iCre⁺, n = 4).
