Since the global financial crisis of 2008, research on supply chain finance (SCF) based management (SCM) has increased rapidly. The context SCF development is continuously changing, which means that it cannot function in isolation and ecology must be taken into consideration. Previous shown comprehensive studies incorporating are lacking; although was mentioned, at a descriptive level with frag...

The proliferation and differentiation of human mast cells (MCs) occur under the influence of the mitogenic agent known as stem cell factor (SCF). This study analyses the distribution of SCF and SCF receptor in human myometrial tissue to further the understanding of the role(s) of MCs in the uterus. Immunohistochemical staining revealed that the majority of uterine MCs are located in close proxi...

Stem cell factor (SCF) is produced by stromal cells as a membrane-bound molecule, which may be proteolytically cleaved at a site close to the membrane to produce a soluble bioactive form. The proteases producing this cleavage are unknown. In this study, we demonstrate that human mast cell chymase, a chymotrypsin-like protease, cleaves SCF at a novel site. Cleavage is at the peptide bond between...

Human kit ligand (KL), also known as stem cell factor (SCF), steel factor, or mast cell growth factor, is a recently identified hematopoietic growth factor whose receptor is the product of the c-kit proto-oncogene. Alternative splicing of the pre-mRNA of KL/SCF results in secreted and membrane-bound forms of the protein. We and others have recently shown that the c-kit gene product is expressed...

BACKGROUND AND PURPOSE Stroke is the leading cause of adult disability worldwide. Currently, there is no effective treatment for stroke survivors. Stem cell factor (SCF) and granulocyte-colony stimulating factor (G-CSF) are the growth factors regulating hematopoiesis. We have previously observed that SCF and G-CSF have neuroprotective and functional effects on acute brain ischemia. In the prese...

The kit ligand (KL), also termed stem cell factor (SCF), is a recently discovered hematopoietic growth factor that augments response of early progenitor cells to other growth factors and supports proliferation of continuous mast cell lines. Histological studies suggest that the receptor for SCF/KL, the c-kit proto-oncogene product, is present in bone marrow megakaryocytes. We studied the effect...

BACKGROUND Airways repair is critical to lung function following transplantation. We hypothesised that the stem cell factor (SCF) could play a role in this setting. METHODS We studied 9 lung transplant recipients (LTx recipients) during their first year postgraft, and evaluated SCF mRNA expression in bronchial biopsy specimens using on-line fluorescent PCR and SCF protein levels in bronchoalv...

PURPOSE Chemotherapy-induced apoptosis of immature hematopoietic cells is a major cause of anemia and thrombocytopenia in cancer patients. Although hematopoietic growth factors such as erythropoietin and colony-stimulating factors cannot prevent the occurrence of drug-induced myelosuppression, stem cell factor (SCF) has been previously shown to protect immature erythroid and megakaryocytic cell...

1. Stem cell factor (SCF) is a major mast cell growth factor that promotes differentiation and chemotaxis of mast cells and inhibits their apoptosis. 2. We evaluated the effect of interleukin (IL)-1beta, a major pro-inflammatory cytokine, on the constitutive expression of SCF and studied the effects of two glucocorticoids, budesonide and dexamethasone, on the IL-1beta-enhanced SCF expression. 3...

To assess the regulation of stem factor factor (SCF) gene expression during spermatogenesis, we tested the effects of hormones (FSH, testosterone, and 17beta-estradiol) and some growth factors [transforming growth factor-beta (TGF beta), TGF alpha, tumor necrosis factor-alpha, and activin] on SCF gene expression by using a transillumination-assisted microdisection technique, a seminiferous tubu...
