BACKGROUND In multiple myeloma, bone marrow mesenchymal stromal cells support myeloma cell growth. Previous studies have suggested that direct and indirect interactions between malignant cells and bone marrow mesenchymal stromal cells result in constitutive abnormalities in the bone marrow mesenchymal stromal cells. DESIGN AND METHODS The aims of this study were to investigate the constitutiv...

background: bone marrow and umbilical cord stromal cells are multipotential stem cells that have the ability to produce growth factors that play an important role in survival and generation of axons. the goal of this study was to evaluate the effects of the two different mesenchymal stem cells on peripheral nerve regeneration. materials and methods: in this experimental study, a 10 mm segment o...

INTRODUCTION: The hierarchy of stromal progenitors from the bone marrow is poorly characterized; multipotent mesenchymal cells and colony-forming units fibroblasts are isolated in culture. Mesenchymal stem do not have a unique combination surface antigens, making it difficult to obtain pure population. expression nestin gene often used as marker these cells.
 AIM: To evaluate level charact...

objective(s) mesenchymal stem cells (mscs) are nonhematopoietic stromal cells that are capable of differentiating into and contribute to the regeneration of mesenchymal tissues. human mesenchymal stem cells (hmscs) are ideal targets in cell transplantation and tissue engineering. enhanced green fluorescent protein (egfp) has been an important reporter gene for gene therapy. the aim of this stud...

Secondary lymphoid tissues such as lymph nodes are essential for the interactions between antigen presenting cells and lymphocytes that result in adaptive immune responses that protect the host against invading pathogens. The specialized architecture of these organs facilitates the cognate interactions between antigen-loaded dendritic cells and lymphocytes expressing their specific receptor as ...

Multipotent mesenchymal stromal cells (MMSCs) are plastic-adherent cells with a well-established phenotype. Equine, but not human, adipose MMSCs have been characterized ultrastructurally. The purpose of our study was to evaluate ultrastructurally the adipose-derived human MMSCs. Cell cultures were prepared from human lipoaspirate. The flow cytometry evaluation of surface markers of cultured cel...

A non-invasive method to characterize human mesenchymal stromal cells during adipogenic differentiation was developed for the first time. Seven fatty acid methyl esters (FAMEs), including methyl laurate, methyl myristate, methyl palmitate, methyl linoleate, methyl oleate, methyl elaidate and methyl stearate, were used for characterizing adipogenic differentiation using headspace solid-phase mic...

BACKGROUND Metastatic spread of tumor cells remains a serious problem in cancer treatment. Gene-directed enzyme/prodrug therapy mediated by tumor-homing genetically engineered mesenchymal stromal cells (MSC) represents a promising therapeutic modality for elimination of disseminated cells. Efficacy of gene-directed enzyme/prodrug therapy can be improved by combination of individual systems. We ...
