N	normal phenotype

immune system

abnormal mast cell physiology ( J:142439 )

• bone marrow derived mast cells proliferate at 60% the rate as controls when cultured for three days with SCF

• these mast cells also have a third slower migration rate towards SCF in transwell assays than controls

• in vivo, less mast cells migrate to the skin when SCF is administered than in controls

decreased mast cell degranulation ( J:145444 )

• bone marrow derived mast cells have a 3-fold reduction in granule release upon Fc-epsilionRI stimulation compared to controls

• calcium flux from the extracellular environment is significantly reduced after receptor stimulation compared to controls

• when passive cutaneous anaphylaxis (PCA) is induced in the ear of mice, the mast cells fail to respond

• similar results are observed when mutant mast cells are transferred into mast-cell deficient mice and PCA is induced

immune system

abnormal mast cell physiology ( J:142439 )

• bone marrow derived mast cells proliferate at 60% the rate as controls when cultured for three days with SCF
