phenotype observed in females
phenotype observed in males
N normal phenotype
mortality/aging
• median survival is 430 days

hematopoietic system
• impaired ability to engraft in a competitive repopulation assay
• severe block in B cell development with few cells progressing past the early pro-B cell stage
• normal architecture is largely replaced by myeloid progenitors in mice at 3 and 12 months of age
• decrease in the fraction of functional c-Kit+ Sca-1+ Lin-(KSL)-signaling lymphocyte activation molecule (KSL-SLAM) cells
• increase in the fractions of c-Kit+ Sca-1+ Lin- (KSL) and multipotent progenitor (Lin-c-Kit+Sca-1+CD135+CD34+) cells in the bone marrow
• architecture disruption and cellular expansion at 3 and 12 months of age
• detected at 12 weeks of age
• treatment with either Lestaurtinib or Sorafenib decreases bone marrow cell proliferation

skeleton
