hematopoietic system
increased B cell apoptosis ( J:194616 )
• in pro-B, pre-B and immature B cells of tamoxifen-treated mice
• however, apoptosis is rescued by exogenous Bcl2 or Mdm2 and Bcl2
decreased pro-B cell number ( J:194616 )
• in the bone marrow of tamoxifen-treated mice
abnormal T cell differentiation ( J:194616 )
• few early T cell progenitors in the thymus of tamoxifen-treated mice
decreased DN2 thymocyte number ( J:194616 )
• in tamoxifen-treated mice
abnormal common lymphocyte progenitor cell morphology ( J:194616 )
• reduced 7-fold in tamoxifen-treated mice
decreased B cell number ( J:194616 )
• in the bone marrow of tamoxifen-treated mice
• however, the number of B cells in the spleen, lymph node and peripheral blood is normal
decreased immature B cell number ( J:194616 )
• to one-fifth of wild-type levels in the bone marrow of tamoxifen-treated mice
decreased pre-B cell number ( J:194616 )
• in the bone marrow of tamoxifen-treated mice
decreased hematopoietic stem cell number ( J:194616 )
• reduced LSK and lymphoid-primed multipotent progenitors in tamoxifen-treated mice
abnormal hematopoietic stem cell physiology ( J:194616 )
• tamoxifen-treated LSK cells exhibit a complete loss of lymphoid development
