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

ABSTRACT: 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.

Experiment Overall Design: Using the same culture conditions, 3 paired PBMSCs and BMMSCs were obtained from 3 different GFP rats. Total cellular RNA of the passage 2 cells was isolated using a total RNA extraction mini kit and processed for the comparative gene expression profile study. Thus, within the total 6 hybridizations, there were 2 comparative groups containing 3 samples in each and each of the 3 samples in one group were paired with one of the other 3 samples in the other group.

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

Project description: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.

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

Mesenchymal stromal cell transcriptome study

Project description:Transcriptomes of mesenchymal stromal cells from bone marrow (bmMSC) were compared to MSC from term placenta (pMSC). Cells were expanded under GMP-compliant conditions. The transcriptome was explored to compare the regenerative potential of bmMSCs and pMSCs in a pre-clinical and eventually in a clinical context

Mesenchymal progenitors from hESCs & profiling vs. BMMSCs

Project description:New potential sources of stem cells for clinical application include bone marrow mesenchymal stem cells (BMMSCs), human embryonic stem cells (hESCs), and induced pluripotent stem cells (iPS). However, each source is not without its own concerns. While research continues in an effort overcome these problems, the generation of mesenchymal progenitors from existing hESC lines may circumvent many of these issues. We report here a comparison of the transcriptome of hESC-derived mesenchymal progenitors (EMPs), its parental hESC line, and 2 donors of adult BMMSCs. A custom-designed oligo-microarray of just over 11,000 highly-expressed genes in stem cells was used to profile the transcriptome of BMMSCs, EMPs, and hESCs.

Gene modification by fast-track recombineering for cellular localization and isolation of components of plant protein complexes

Project description:Genes encoding Arabidopsis subunit homologs of TFIIH kinase module were labelled with coding sequences of GFP and mCherry (green and red fluorescent proteins) using fast-track recombineering. To illustrate the applicability of recombineering for accelerating the isolation and identification of plant protein complexes, proteins associated with CDKD;2-GFP, CYCLIN-H-mCherry and DNA replication-dependent HISTONE H3.1-mCherry complexes were purified on GFP-Trap and RFP-TRAP and analysed by LC-MS/MS mass spectrometry. The results confirmed association of know TFIIH subunit homologs with CDKD;2 and CYCLIN H, and identified subunits of CAF1 (CHROMATIN ASSEMBLY FACTOR 1) and ASF1A/B histone chaperon in complex with HISTONE H3.1.
