hematopoietic system
• expression analysis indicates a defect in the maturation of both medullary and cortical epithelial cells
• limited thymic epithelial architecture quickly deteriorates in postnatal mice with discrete cortical and medullary structures no longer seen at 3 weeks of age
• expression analysis indicates impaired proliferation of developing epithelial cells
• the double negative population is over-represented and composed primarily of B220+ B lineage cells instead of T lineage precursors
• however, the absolute number of B lineage cells in the thymus is similar to controls
• the T cell compartment in the periphery is never fully established in adult mice
• the CD3+ population in the spleen is small
• markedly reduced in proportion in the thymus at 3 weeks of age
• barely detectable at 6 weeks of age
