Expression data from rat lung-resident mesenchymal stem cells and bone marrow-derived mesenchymal stem cells

ABSTRACT: Rat lung-resident mesenchymal stem cells (LR-MSCs) were isolated via bronchoalveolar lavage from fibroblast growth factor-10 (FGF-10) pretreated lungs. We characterized the similarity and diversity between LR-MSCs and bone marrow-derived mesenchymal stem cells (BM-MSCs) by transcriptional profiling of these two types of cells. In this dataset, we include the expression data obtained from LR-MSCs and BM-MSCs cultured under similar conditions at passage 5. These data are used to obtain genes that are differentially expressed by these two types of cells.

Expression data from Mesenchymal stem cells

Project description:Abnormal osteogenic differentiation of mesenchymal stem cells (MSCs) is implicated in the pathogenesis of Adolescent idiopathic scoliosis(AIS). However, the biological roles of long noncoding RNAs (lncRNAs) in the regulation of osteogenic differentiation of MSCs are unknown. We used LncRNA microarray analyses of bone marrow (BM) MSCs from non-AIS patients and AIS patients and identified significant differentially expressed lncRNAs in AIS BM-MSCs.

Human native bone marrow CD200 positive mesenchymal stromal cells exhibit characteristics of cells forming the hematopoietic stem cell niche

Project description:Bone marrow (BM) mesenchymal stem/stromal cells are non-hematopoietic (CD45-), non-endothelial (CD31-) multipotential cells capable to differentiate into osteoblastes, chondrocytes and adipocytes. In addition, different subpopulations of MSCs and some of their derivatives (early osteoblastic lineage cells) were shown to form HSC-niche. This makes a complex picture of the relationship between MSCs and HSCs. Despite growing data in mice model, few describe the human counterpart. The BM CD200+ and CD271+ fractions were previously shown to be enriched in native MSCs in human. Herein, we found heterogeneity in expression of CD200 within CD45-/CD31-/CD271+ human BM fraction. We thus selected CD200+ and CD200- cells from CD45-/CD31-/CD271+ BM samples and we analyzed their transcriptome. The differential display of gene expression between these two types of BM fractions will give new insights in the identification of native human MSCs.

Expression data from endothelial cells induced from bone marrow mesenchymal stem cells with SCD1 overexpression

Project description:Bone marrow mesenchymal stem cells (BM-MSCs) are of multi-differentiating potential and has been demonstrated to have the ability to differentiate into endothelial cells. Stearoyl-CoA desaturase 1 (SCD1) is a key enzyme in lipid metabolism, which can convert saturated fatty acids into unsaturated fatty acids. We used lentivirus to transfected SCD1 gene into BM-MSCs and found that overexpression of SCD1 could promote the differentiation of BM-MSCs into endothelial cells. We used microarrays to detect the differential gene expression profile of endothelial induced BM-MSCs with SCD1 overexpression.

Microarray analysis of differences in miRNA expression between human mesenchymal stem cells isolated from olfactory mucosa and bone

Project description:This experiment investigates differences in miRNA expression between different populations of human mesenchymal stem cells (MSCs), which are a potential treatment for multiple sclerosis (MS). Previously it has been reported that MSCs derived from human olfactory mucosa (OM-MSCs) may be a better candidate for the treatment of MS than MSCs derived from bone marrow (BM-MSCs), due to a better ability to promote CNS myelination in vitro. In this study, miRNA profiling of OM-MSCs and BM-MSCs was undertaken to investigate the differences between these two cell types in relation to their prospective therapeutic use.

miR-7977 transfer alter the transcriptome in bone marrow mesenchymal stem cells.

Project description:Acute myeloid leukemia (AML) cells release abundant exosomal miR-7977 that transfer into bone marrow (BM) mesenchymal stromal cells (MSCs). We have shown that exosomal miR-7977 was highly released from AML cells and was transferred into BM MSCs. It has been well known that a microRNA has multiple targets. In fact, miRDB predicted 633 targets. Based on these findings, control and miR-7977mimic were transferred into BM MSCs. Subsequently, alteration of transcriptome was analyzed to gain insight into the role of miR-7977 in bone marrow micro environment.

miR-146a-5p circuitry uncouples cell proliferation and migration, but not differentiation, in human mesenchymal stem cells

Project description:Administration of mesenchymal stem cells (MSCs) has the potential to ameliorate degenerative disorders and to repair damaged tissues. The homing of transplanted MSCs to injured sites is a critical property of engraftment. Our aim was to identify microRNAs involved in controlling MSC proliferation and migration. MSCs can be isolated from bone marrow and umbilical cord Wharton's jelly (BM-MSCs and WJ-MSCs, respectively), and WJ-MSCs show poorer motility yet have a better amplification rate compared to BM-MSCs.

Expression data from porcine mandibular- and tibial-derived bone marrow mesenchymal stem cells.

Project description:Objective: Craniofacial bone defects caused by injuries and congenital diseases are a formidable challenge to clinicians. Research has shown promise in using bone marrow mesenchymal stem cells (BM-MSCs) from limb bones for craniofacial bone regeneration; yet little is known about the potential of BM-MSCs from craniofacial bones. This study compared BM-MSCs isolated from limb and craniofacial bones in pigs, a preclinical model closely resembling humans. Design: Bone marrow was aspirated from the tibia and mandible of four-month-old pigs (n=4), followed by BM-MSC isolation, culture-expansion and confirmation by flow cytometry. Proliferation rates were compared using population doubling times. Osteogenic differentiation was evaluated by quantifying alkaline phosphatase (ALP) activity. Total mRNA was extracted from freshly isolated BM-MSCs and analyzed to compare gene expressions of tibial and mandibular BM-MSCs using an Affymetrix GeneChip porcine genome array, followed by real-time RT-PCR evaluation of two neural crest markers. Results: BM-MSCs from both locations expressed MSC markers without expression of hematopoietic markers. Mandibular BM-MSCs proliferated significantly faster than tibial BM-MSCs. Without osteogenic inducers, mandibular BM-MSC alkaline phosphatase activities were 3.3-fold greater than those of tibial origin. Microarray analysis identified 383 differentially expressed genes in mandibular and tibial BM-MSCs, including higher expression of cranial neural crest-related genes nestin and BMP-4 in mandibular BM-MSCs, a trend also confirmed by real-time RT-PCR. Among differently expressed genes, only 47 showed greater than 1.5-fold differences in expression. Conclusions: These data indicate that despite many similarities in gene expression, mandibular BM-MSCs express of number of genes differently than tibial BM-MSCs and have a phenotypic profile that may make them advantageous for craniofacial bone regeneration.

An insight into Exosomal Cargo Isolated from three tissue specific Mesenchymal Stem Cells: Implication in Translational Research

Project description:Adult Mesenchymal stem cells (MSCs) derived exosomes have recently gained importance as a cell-free therapy for several chronic and inflammatory diseases. It is believed that these exosomes contain several biologically active molecules (i.e. miRNAs, proteins) which help to cure the diseases. The majority of published reports to date that have investigated the secretome of MSCs have done so using canonical expansion of cell culture conditions. However, the microenvironment experience by MSC post administration into animal models and patients is strikingly different. Thus instead of using secretome, Exosomes purified from adipose tissue (AD), Wharton Jelly (WJ) and Bone marrow BM) are widely studied. However, the content of the exosomes may differ based on their sources from where they are originated. It remains unclear, however, which types of proteins are packaged into exosomes compared with the cells from which they are derived. To explore these exosomes as a cell-free therapy for specific diseases, it is therefore, important to get comprehensive knowledge of the bioactive molecules present in the exosomes. In this study, we have purified the exosomes from three different sources (AD, WJ, and BM) and using RNA-Seq approach, we have categorized the common and different microRNAs present in the exosomes.
