Despite high interests on microenvironmental regulation of leukemic cells, little is known for bone marrow (BM) niche in leukemia patients. Our recent study on BMs of acute myeloid leukemia (AML) patients showed that the mesenchymal stromal cells (MSCs) are altered during leukemic conditions in a clinical course-dependent manner. Leukemic blasts caused reprogramming of transcriptomes in MSCs an...
Mesenchymal stromal cells (MSCs) are one of the most intensively studied stem cell types with application aims. However, the molecular characterisation and the relationship between the molecular characterisation and functional properties of MSCs are largely unknown. In this study, we purified the surface proteins from rat bone marrow MSCs (rBMMSCs) and characterised their surface proteome by LC...
The contribution of the bone marrow microenvironment in myelodysplastic syndrome is controversial. We therefore analyzed the functional properties of primary mesenchymal stromal cells from patients with myelodysplastic syndrome in the presence or absence of lenalidomide. Compared to healthy controls, clonality and growth were reduced across all disease stages. Furthermore, differentiation defec...
1.1 The definition of MSCs Bone marrow (BM) was the first tissue described as a source of plastic-adherent, fibroblastlike cells that develops colony-forming unit fibroblastic (CFU-F) when seeded in tissue culture plates (Friedenstein et al., 1982; 1987). These cells, originally designated stromal cells, elicited much attention, and the main goal of thousands of studies conducted using these ce...
The engraftment capacity of bone marrow-derived mesenchymal cells was investigated in 41 patients who had received a sex-mismatched, T-cell-depleted allograft from human leukocyte antigen (HLA)-matched or -mismatched family donors. Polymerase chain reaction (PCR) analysis of the human androgen receptor (HUMARA) or the amelogenin genes was used to detect donor-derived mesenchymal cells. Only 14 ...
We have studied a rapid cultivation method for human mesenchymal stromal cells based on CellGroTM medium and human serum, supplemented with insulin, ascorbic acid, dexamethasone, epidermal growth factor, platelet-derived growth factor BB, macrophage colony-stimulating factor and fibroblast growth factor 2. This study has shown that ...
More than 95% of ovarian cancers originate from the epithelial cells on the surface of the ovary, which are termed ovarian surface epithelium (OSE). These OSE cells are modified peritoneal mesothelial cells separated from underlying ovarian surface stromal tissue by a basal lamina of dense collagenous connective tissue. Mesenchymal-epithelial cell interactions between stromal cells and OSE cell...
Background & Aim: Gastrointestinal stromal tumors(GISTs) are the most common mesenchymal tumors of gastrointestinal tract. They are known to express c-kit, which is important in their diagnosis and treatment. The aim of our study was to assess the morphologic and immunohistochemical features of gastrointestinal stromal tumors and the significance of c-kit expression in them. Materials and M...
