N
• spleen architecture is largely restored compared to Lta-deficient mice; extensive networks of T zone stromal cells are observed
• splenic dendritic cell numbers are restored
• although T zone stromal areas are extensive compared to Lta-deficient mice, distribution of gp38+ staining differs from wild-type with a higher concentration of positive cells near the boundary of the B and T zones
• transgene expression does not restore lymph node or Peyer's patch development in Lta-deficient mice

hematopoietic system
• although T zone stromal areas are extensive compared to Lta-deficient mice, distribution of gp38+ staining differs from wild-type with a higher concentration of positive cells near the boundary of the B and T zones
