CD90
  • Also called Thy-1
  • May mediate differentiation of hematopoietic stem cells and synaptogenesis in the CNS
  • CD34+ CD90+ cells include hematopoietic stem cells that serve as autologous grafts to replace the bone marrow in patients with malignancies (Biol Blood Marrow Transplant 2000;6:262)
  • Mediates adhesion of various white blood cells to activated endothelial cells (J Immunol 2004;172:3850)
  • Uses by pathologists: hematopoietic stem cell marker
  • Positive staining - normal:
  • Negative staining - disease: Ewing sarcoma and some rhabdomyosarcomas (Am J Clin Pathol 2003;119:643)

CDw92
CD93
CD94
CD95
CD96
  • Also called T cell activated increased late expression (TACTILE)
  • May be involved in adhesion of activated T and NK cells late in immune response
  • Binds CD155
  • No significant clinical use by pathologists
  • Positive staining - normal: activated T cells and NK cells, B cells (low levels)
  • Positive staining - disease: T-ALL (Exp Hematol 1998;26:1209)
