hematopoietic system
thymus hypoplasia ( J:87435 )
• thymic cellularity reduced to 1/8 normal
increased double-negative T cell number ( J:87435 )
• most thymocytes are double negative
• a lower percentage of double negative stage 4 cells (DN4) and increase in DN3 cells
decreased T cell number ( J:87435 )
• only moderate reductions in mature T cells in spleen and lymph nodes
decreased double-positive T cell number ( J:87435 )
• absolute numbers of double positive cells reduced
