cx2

• Allelic Composition: Stat5a^tm1Jni/Stat5a^tm1Jni; Stat5b^tm2Jni/Stat5b^tm2Jni
• Genetic Background: involves: 129 * C57BL/6

mortality/aging

premature death ( J:122463 )

• 40% of the mice die within the first few months

immune system

abnormal mast cell differentiation ( J:84889 )

• bone marrow cells die of apoptosis when cultured in WEHI-3 cell-conditioned media that normally supports mast cell differentiation

• mutant bone marrow cells fail to produce mast cells as wild-type bone marrow does when transferred into mast cell deficient kit^w-v mice

• however, mast cells can be derived from bone marrow cells when cultured with IL-3 and SCF

absent mast cells ( J:84889 )

• mast cells are absent in these mice as determined by histology and flow cytometry

decreased CD4-positive, CD25-positive, alpha-beta regulatory T cell number ( J:122463 )

• reduction of CD4+CD25+ suppressor T cells

abnormal mast cell physiology ( J:84889 )

• bone marrow derived mast cells die of apoptosis when culture is supplemented with only low levels of IL-3 or SCF

• 80-fold more IL-3 or 50-fold more SCF is needed than controls to prevent apoptosis in cultured mast cells

• mast cells delay entering into S-phase when cultured with SCF or IL-3 taking almost twice as long as to reach half-maximal entry into S phase

• these mast cells survive and proliferate when cultured with IL-3 and SCF
