We found that c-kit-positive, lineage marker-negative, Thy-1lo cells are present in both bone marrow and thymus ("BM c-kit" and "thymus c-kit" cells). Although the two cell types are phenotypically similar, only BM c-kit cells showed the potential to form colonies in vitro as well as in vivo. However, both of them revealed extensive growth and differentiation potential to T cells after direct t...
c-Kit, a receptor tyrosine kinase, is involved in intracellular signaling, and the mutated form of c-Kit plays a crucial role in occurrence of some cancers. The function of c-Kit has led to the concept that inhibiting c-Kit kinase activity can be a target for cancer therapy. The promising results of inhibition of c-Kit for treatment of cancers have been observed in some cancers such as gastroin...
Most mouse thymocytes undergoing positive selection are found on one of two pathways; the c-Kit+ and the c-Kit- pathways. Here, we show that c-Kit and interleukin-7 receptor (IL-7R)-mediated signals support positive selection during the transition from the subpopulation that first expresses cell surface T cell receptor (TCR)-the TCRalpha/betaloCD4(int)/CD8(int) (DPint) c-Kit+ cells to TCRalpha/...
The stem cell factor c-kit signaling pathway (SCF/c-kit) has been previously implicated in normal hematopoiesis, melanogenesis, and gametogenesis through the formation and migration of c-kit(+) cells. These biologic functions are also determinants in epithelial-mesenchymal transitions during embryonic development governed by the Snail family of transcription factors. Here we show that the activ...
We have analyzed c-kit expression by hematopoietic progenitors from normal and 5-fluorouracil (5-FU)-treated mice by staining with monoclonal anti-c-kit antibody ACK-4. Marrow cells that were enriched for progenitors by a combination of metrizamide density separation and negative immunomagnetic selection with lineage-specific monoclonal antibodies (MoAbs) were separated into three populations b...
BACKGROUND Adipose tissue-derived mesenchymal stem cells (ASCs) improve the regenerative ability and retention of fat grafts for breast reconstruction in cancer patients following mastectomy. However, ASCs have also been shown to promote breast cancer cell growth and metastasis. For the safety of ASC application, we aimed to identify specific markers for the subpopulation of ASCs that enhance t...
The Src-like-adaptor protein (SLAP) is an adaptor protein sharing considerable structural homology with Src. SLAP is expressed in a variety of cells and regulates receptor tyrosine kinase signaling by direct association. In this report, we show that SLAP associates with both wild-type and oncogenic c-Kit (c-Kit-D816V). The association involves the SLAP SH2 domain and receptor phosphotyrosine re...
BACKGROUND Receptor tyrosine kinase, c-Kit (CD117) plays a pivotal role in the maintenance and expansion of hematopoietic stem/progenitor cells (HSPCs). Additionally, over-expression and/or mutational activation of c-Kit have been implicated in numerous malignant diseases including acute myeloid leukemia. However, the translational regulation of c-Kit expression remains largely unknown. METHO...
