Aldh2-deficient mast cells showed enhanced Kit tyrosine kinase phosphorylation and activity after stimulation with its ligand (stem cell factor) and augmentation of downstream signaling pathways, including Stat4, MAPKs, and Akt. The cytokine stem cell factor (SCF) is mandatory for normal mast cell development; mice of the WBB6F1‐Kit W /Kit W‐v strain that have a dysfunctional form of the SCF receptor (c‐kit) have essentially no tissue mast cells 21. The activity of the phosphatase Shp-1, which attenuates Kit activity, was reduced in Aldh2−/− mast cells, along . We histologically observed a large number of mast cells in the upper dermis, some of which had migrated into the epidermis, while SCF expression was detected on the tumor cells. BM cells were grown for 3 weeks in presence of interleukin-4 (IL-4) plus stem cell factor (SCF). Immunohistochemistry demonstrated positive perinuclear staining in a cytoplasmic pattern for SCF on tumor cells, mast cells, endothelial cells, and keratinocytes in the acanthotic epidermis in both cases. That is, some mast cell growth-inducing factors may be released from lymphoid tumor cells or activated keratinocytes, and chemokines for mast cells might also be released from epidermal cells. As controls, serum was obtained from 3 patients with infiltrative stage MF without either diffuse pigmentation or itching, and from 10 normal volunteers (5 males and 5 females; age range, from 44 to 60 years). The Kit ligand SCF or stem cell factor (SCF) is a multipotent growth factor, acting as an important growth factor for human mast cells. 1987 Sep;24(9):568-71 Cell surface receptor regulation maintains proper responses to external signals and disregulation of receptors can have drastic effects. We analyzed the effects of recombinant human SCF (r-hSCF, 5-50 micrograms/kg/day, injected subcutaneously) on mast cells and melanocytes in a phase I . The first is the allergic response via the high affinity IgE receptor. A role for SCF may thus be hypothesized in diseases associated with a local increase in the number and/or activation of mast cells, as occurring in the airways in asthma. We investigated whether SCF influenced the response of mouse mast cells to an IgE-independent stimulus, eosinophil-derived granule major basic protein (MBP). It is a glycoprotein important for differentiation, proliferation, and development of many cell types, including melanocytes, mast cells, germ cells, and intestinal cells. Careers.
