The gene expression pattern of bone marrow mesenchymal stem cells from patients with psoriasis

ABSTRACT: Object: To study the difference of gene expression pattern of bone marrow mesenchymal stem cells (BMMSCs) between psoriatic patients, normal adults and aborted fetuses, and then to explore the influence of bone marrow mesenchymal stem cells to immune system. Methods: Bone marrow mononuclear cells (BMMNC) of 7 psoriatic patients, 4 healthy volunteers and 3 aborted fetuses were isolated and the BMMSCs were cultured using the adherent method. Gene expression of 14 samples was detected by gene microarray and the different expressed genes were analysised by SAM software. Results: 654 differentially expressed genes (66 up regulated, 588 down regulated) were detected between the psoriatic patients and normal adults, which were enriched in immune response, chemotaxis and cell adhesion etc. 2020 differentially expressed genes (888 up regulated, 1132 down regulated) were detected between the aborted fetuses and normal adults. These genes were enriched in cell cycle, cell division, immune response and MHC class II antigen etc. Conclusion: The gene expression pattern such as immune response, chemotaxis was aberrant in psoriatic BMMNCs, which was consistent with aborted fetuses in some immune related genes. Bone marrow mononuclear cells (BMMNC) of 7 psoriatic patients, 4 healthy volunteers and 3 aborted fetuses were isolated and the BMMSCs were cultured using the adherent method. Gene expression of 14 samples was detected by gene microarray and the different expressed genes were analyzed by SAM software.

Gene expression signatures for rat liver grafts

Project description:Acute rejection remains an important risk factor affecting the survival of recipients following transplantation. Bone marrow mesenchymal stem cells (BMMSCs) are used in the treatment of organ transplantation due to their immunomodulatory ability. BMMSCs were isolated from rat bone marrow and modified with the adenovirus for heme oxygenase 1 (HO-1) gene. Saline solution, BMMSCs or HO-1/BMMSCs were perfused into the donor liver in vitro using a normothermic machine perfusion (NMP) system, followed by liver transplantation. The liver grafts were collected at 7 days post-transplantation. Gene chip technology was used to detect differential gene expression.

Bone marrow-derived multipotent mesenchymal stromal cells promote tongue cancer invasion by inducing collagen production

Project description:Tumor microenvironment (TME) is an active player in malignant growth and spread. Changes in the composition and structure of TME and extracellular matrix can result in either suppression or facilitation of malignant tumor growth. Carcinoma‐associated fibroblasts, bone marrow-derived multipotent mesenchymal stromal cells (BMMSCs), tumor associated macrophages and other inflammatory cells all affect the composition of TME, proliferation and survival of cancer cells, angiogenesis, invasion and metastasis. The objective of this work was to investigate the effect of the interaction between bone marrow-derived BMMSCs and human oral tongue squamous cell carcinoma (OTSCC) cells in the processes of invasion and gene expression. Co-cultures of OTSCC cancer cells and BMMSCs in 3D organotypic invasion assay were used in addition to cell culture, immunological, microarray, and RNA interference techniques. Total number of 4 samples were analyzed. 2 replicates of cultured human oral tongue squamous cell carcinoma (OTSCC) cells, and 2 replicates of OTSCC cells co-cultured with bone marrow-derived multipotent mesenchymal stromal cells

Transcriptional gene profile of peripheral blood derived mesenchymal stromal cells from GFP transgenic rat

Project description:Using culture conditions similar to those defined for bone marrow derived mesenchymal stromal cells (BMMSCs), peripheral blood derived mesenchymal stromal cells (PBMSCs) from green fluorescent protein (GFP) transgenic rats were isolated and expanded. Despite the highly similar profile in the putative mesenchymal characteristics including fibroblastic morphology, molecular markers such as CD90, CD44, CD106, vimentin, etc., osteogenic and adipogenic differentiation potentials, significant differential expression between PBMSCs and BMMSCs was discovered in 167 genes by Affymetrix microarray. Of the 167 sequences, were there 81 genes up-regulated and 86 genes down-regulated in the PBMSCs vs BMMSCs. The gene ontological (GO) analysis further revealed that ontology terms such as cell differentiation, development, cell communication, extracellular region, etc., were significantly enriched in these 167 genes, implying potential different biological function of PBMSCs from their counterpart BMMSCs. These genes and associated proteins may also be used as markers for defining PBMSCs from BMMSCs, and more important, may provide further direction to study this elusive cell population. Keywords: mesenchymal stromal cells (MSCs), peripheral blood (PB), bone marrow (BM), green fluorescent protein (GFP) transgenic rat, microarray

Human bone-derived mesenchymal stem cells: SLE patients vs normal controls

Project description:Previous studies showed that bone marrow derived-mesenchymal stem cells (BMMSCs) from patients with systemic lupus erythematosus (SLE) and lupus animal models have deficiency in their capacities of proliferation, differentiation, secretion of cytokines and other functions. In this study, we aim to investigate the different gene patterns of BMMSCs between normal and SLE individuals using genome-scale DNA microarrays. We found that among all the genes investigated in microarray slides, a total of 1, 905 genes were differentially expressed by BMMSCs SLE patients, in which 652 genes were up-regulated and 1253 genes were down-regulated. Gene ontology analysis showed that the majority of these genes were related to cell cycle and protein binding. Pathway analysis showed that differentially regulated signal pathways involved actin cytoskeleton, focal adhesion, tight junction and TGF-β pathway. Our data suggested that there were differential gene expression patterns of BMMSCs between normal and SLE individuals, and further studies are needed to reveal the mechanisms for such differences. Bone marrow (BM) was obtained from 4 patients with SLE and 4 normal controls. BMMSCs were cultured and mRNA was extracted. Standard human reference RNA were purchased. Every slide: SLE or normal vs control, then SLE vs normals.

DNA methylation in progenitor cells: MeDIP study

Project description:We surveyed DNA methylation profiles of all human RefSeq promoters in relation to gene expression and differentiation in adipose tissue, bone marrow and muscle mesenchymal progenitors, as well as in bone marrow-derived hematopoietic progenitors. We unravel strongly overlapping DNA methylation profiles between adipose stem cells (ASCs), bone marrow mesenchymal stem cells (BMMSCs) and muscle progenitor cells (MPCs), while hematopoietic progenitor cells (HPCs) are more epigenetically distant from MSCs seen as a whole. Differentiation resolves a fraction of methylation patterns common to MSCs, generating epigenetic divergence.
