Figure A1.
Altered maturation of CD4+ SP medullary thymocytes in the fetal thymus of lig4R/R and rag1S/S mice. Upper panels: Representative FACS plots of CD4+ SP medullary thymocytes at various stages of maturation according to the expression of CD69 and Qa2 surface markers. Lower panels: Distribution of the different populations of SP1–SP4 cells. lig4R/R and rag1S/S mice have a significant accumulation of SP3 thymocytes. Mean values ± SE are shown. At least three to five mice per group were analyzed.
