Background Mesenchymal stem cells (MSC) are adult stem cells present in bone marrow (BM), fat and in many other tissues. MSC have strong immunosuppressive qualities in vitro. The immunosuppression seems to work both by paracrine action and cell-cell contact. MSC inhibit NKcells, B-cells, dendritic cells, Th1-cells and activate regulatory T-cells. The presence of floating single MSC in human syn...
We present methods to characterize mesenchymal stromal cells (MSC) over long time periods in vitro. The methods entail passaging cells multiple times and performing differentiation studies with the cells at each passage. Using an array of surface markers and flow cytometric quantification, the data can be correlated to traditional measures of differentiation such as PCR and staining. Using thes...
Myelodysplastic syndrome (MDS) are a group of progressive, clonal, neoplastic bone marrow disorders characterized by hematopoietic stem cell dysregulation and abnormalities in the immune system. Mesenchymal stem cells (MSC) have gained further interests after the demonstration of an immunoregulatory role. Nevertheless, the immunoregulatory function of MDS bone marrow derived MSC (MDS-MSC) remai...
Mesenchymal stem cells are showing increasing promise in applications such as tissue engineering and cell therapy. MSC are low in number in bone marrow, and therefore in vitro expansion is often necessary. In vivo, stem cells often reside within a niche acting to protect the cells. These niches are composed of niche cells, stem cells, and extracellular matrix. When blood vessels are damaged, a ...
the aim of this study was to investigate the interactions between rat intestine decellularized scaffold and human adipose derived mesenchymal stem cells. rat large intestine was dissected in fragments and decellularized by physicochemical methods. the scaffolds were loaded by human adipose derived mesenchymal stem cells expressing green fluorescent protein. microscopic sections were prepared fr...
INTRODUCTION Normal and malignant breast tissue contains a rare population of multi-potent cells with the capacity to self-renew, referred to as stem cells, or tumor initiating cells (TIC). These cells can be enriched by growth as "mammospheres" in three-dimensional cultures. OBJECTIVE We tested the hypothesis that human bone-marrow derived mesenchymal stem cells (MSC), which are known to sup...
We have previously shown that mesenchymal stem cells (MSC) inhibit tumour cell proliferation, thus promising a novel therapy for treating cancers. In this study, MSC were generated from human bone marrow samples and characterised based on standard immunophenotyping. When MSC were co-cultured with BV173 and Jurkat tumour cells, the proliferation of tumour cells were profoundly inhibited in a dos...
in vitro expansion of mesenchymal stem cell (mscs) into large number is necessary for their application in cell-based treatment of articular cartilage defects. on the other hand, some studies have indicated that bio (6-bromoindirubin-3-oxime) possesses mitogenic effects on cell culture. the objective of the present study was to examine the effect of bio on in vitro expansion and chondrogenic di...
Human tissue repair deficiencies can be supplemented through strategies to isolate, expand in vitro, and reimplant regenerative cells that supplant damaged cells or stimulate endogenous repair mechanisms. Bone marrow-derived mesenchymal stromal cells (MSCs), a subset of which is described as mesenchymal stem cells, are leading candidates for cell-mediated bone repair and wound healing, with hun...
The vast majority of literature pertaining to mesenchymal stem cells (MSC) immunomodulation has focussed on bone marrow-derived MSC that are systemically infused to alleviate inflammatory conditions. Rheumatoid arthritis (RA) is the commonest autoimmune joint disease that has witnessed significant therapeutic advances in the past decade, but remains stubbornly difficult to treat in a subset of ...
