Transcription profiling of monkey bone marrow-derived mesenchymal stem cells to examine the effect of age

ABSTRACT: The objective of this study was to elucidate age-related differences in gene expression profiles of rhesus monkey bone marrow-derived mesenchymal stem cells (rhMSC) obtained from fetal, infant, and adult donors relevant to their growth and other properties. Although a high degree of similarity was observed in the rhMSC gene expression profiles when comparing the three age groups, significant differences were found that strongly parallel gene expression profiles of human MSC. The potential functional relevance of differential gene expression was most apparent when comparing fetal and adult rhMSC transcript profiles. Overall, the observed gene expression profiles are consistent with a loss of rhMSC pluripotency and proliferative capacity with advancing donor age. In addition, these data highlight the importance of use of non-human primates as a model system for studying the properties of human stem cells. Experiment Overall Design: A total of eleven bone marrow-derived mesenchymal stem cell cultures were established from rhesus monkeys of diverse ages (ranging from gestation day 120 to 8 year old adults). Total RNA was harvested from these cultures and gene expression analyses were conducted using oligonucleotide microarrays. The expression profiles of a subset of genes was confirmed by qRT-PCR analysis. A detailed manuscript that details the results of our studies is currently under review.

Gene expression in fetal mesenchymal stem cells for identification of epitopes suitable for non-invasive isolation

Project description:Human mesenchymal stem cells circulate in 1st and early 2nd trimester fetal blood, but not in adults. Like other fetal cell types they cross the placenta, and can be found in maternal organs decades later. To determine potential ligands in human fetal mesenchymal stem cells not present in maternal blood, the gene expression of 1st trimester human fetal bone marrow, liver and blood derived mesenchymal stem cells will be compared to blood mononuclear cells from pregnant women using a Affymetrix human gene array system.

Retroviral Sox17 over-expression adult hematopoietic stem/progenitor cells microarray

Project description:The transcription factor SOX17 is expressed by fetal, but not adult hematoipoietic stem cells (HSCs), and is required for the maintenance of fetal and neonatal, but not adult, HSCs. In the current study we show that ectopic expression of Sox17 in adult HSCs and transiently reconstituting multipotent progenitors was sufficient to confer increased self-renewal potential and the expression of fetal HSC genes including fetal HSC surface markers. To assess the mechanisms by which ectopic Sox17 expression in adult hematopoietic progenitors increased self-renewal potential and conferred fetal HSC properties, we compared the gene expression profiles of E16.5 fetal liver HSCs, young adult bone marrow HSCs, young adult bone marrow CD48+LSK cells, and Sox17-expressing CD48+LSK cells isolated from mice that had been transplanted with MSCV-Sox17-infected bone marrow cells 12 weeks earlier.

Mesenchymal Stromal Cells of Different Donor Age

Project description:In this series we have analyzed the effect of donor age on the gene expression profile of mesenchymal stromal cells (alternatively named mesenchymal stem cells; MSC) from human bone marrow. Cells were taken from bone marrow aspirates from iliac crest (BM) of healthy donors or from the caput femoris (HIP) of elderly patients that received femoral head prosthesis.

Mesenchymal stromal cells in the bone marrow niche consist of multi-populations with distinct transcriptional and epigenetic properties [ATAC-Seq]

Project description:Although multiple studies have investigated the mesenchymal stem and progenitor cells (MSCs) that give rise to mature bone marrow, high heterogeneity in their morphologies and properties causes difficulties in molecular separation of their distinct populations. In this study, by taking advantage of the resolution of the single cell transcriptome, we analyzed Sca-1 and PDGFR-α fraction in the mouse bone marrow tissue. The single cell transcriptome enabled us to further classify the population into seven populations according to their gene expression profiles. We then separately obtained the seven populations based on candidate marker genes, and specified their gene expression properties and epigenetic landscape by ATAC-seq. Our findings will enable to elucidate the stem cell niche signal in the bone marrow microenvironment, reconstitute bone marrow in vitro, and shed light on the potentially important role of identified subpopulation in various clinical applications to the treatment of bone- and bone marrow-related diseases.
