Project description:We used human fetal bone marrow-derived mesenchymal stromal cells (hfMSCs) differentiating towards chondrocytes as an alternative model for the human growth plate (GP). Our aims were to study gene expression patterns associated with chondrogenic differentiation to assess whether chondrocytes derived from hfMSCs are a suitable model for studying the development and maturation of the GP. hfMSCs efficiently formed hyaline cartilage in a pellet culture in the presence of TGFB3 and BMP6. Microarray and principal component analysis were applied to study gene expression profiles during chondrogenic differentiation. A set of 232 genes was found to correlate with in vitro cartilage formation. Several identified genes are known to be involved in cartilage formation and validate the robustness of the differentiating hfMSC model. KEGG pathway analysis using the 232 genes revealed 9 significant signaling pathways correlated with cartilage formation. To determine the progression of growth plate cartilage formation, we compared the gene expression profile of differentiating hfMSCs with previously established expression profiles of epiphyseal GP cartilage. As differentiation towards chondrocytes proceeds, hfMSCs gradually obtain a gene expression profile resembling epiphyseal GP cartilage. We visualized the differences in gene expression profiles as protein interaction clusters and identified many protein clusters that are activated during the early chondrogenic differentiation of hfMSCs showing the potential of this system to study GP development.

Project description:Limbal stromal cells were reported to resemble mesenchymal stem cells (MSCs) with multipotential differentiation cability. However, little is known about their gene expression profiles compared to MSC derived from various sources. In this study, the gene expression profile of limbal stromal cells was compared to bone marrow, adipose stromal cells and foreskin fibroblasts. In addition, we also explored the gene expression changes of ex vivo expanded limbal stromal cells when cultured in two different systems. Expanded limbal stromal cells were divided into two groups; each cultured separately on a matrigel-coated plate in DMEM/F12 medium supplemented with bFGF and LIF and the other on a normal plate in DMEM medium supplemented with 10% fetal bovine serum (FBS). Cryopreserved bone marrow mesenchymal cells, adipose stromal cells and foreskin fibroblasts were cultured-expanded until confluent. Total RNA was extracted from all the samples and subjected to microarray experiments with an Agilent platform by using Human GE 8x60k microarrays. Data analysis was carried out with GeneSpring software. A total of 871 genes were upregulated when the limbal stromal cells were cultured in the matrigel system, whereas 58 genes were consistently differentially expressed in limbal stromal cells compared to other lineages. Besides the long intergenic non-coding RNA and unknown genes, these genes represent gene ontology for cellular components, molecular function and biological process. Samples derived from the same source were closely clustered by Hierachical clustering analysis. The limbal stromal cells have a distinct molecular signature compared to MSCs from other lineages. The culture system affected the gene expression profile of limbal stromal cells tremendously.

Derived limbal stromal cells were cultured using two different methods, one with matrigel and the other with FBS. Their gene expression profiles were compared. The gene expression profile of limbal stromal cells that were cultured with FBS also was compared to the gene expression profiles of bone marrow mesenchymal stem cells, adipose stromal cells and foreskin fibroblasts.

Project description:The aim of the current study was to identify molecular markers for articular cartilage that can be used for the quality control of tissue engineered cartilage. Therefore a genom-wide expression analysis was performed using RNA isolated from articular and growth plate cartilage, both extracted from the knee joints of minipigs. Keywords: Native material or primary cells isolated from articular cartilage and growth plate cartilage

Project description:As an essential cellular component of the bone marrow (BM) microenvironment mesenchymal stromal cells (MSC) play a pivotal role for the physiological regulation of hematopoiesis, in particular through the secretion of cytokines and chemokines. Mass spectrometry (MS) facilitates the identification and quantification of a large amount of secreted proteins (secretome), but can be hampered by the false-positive identification of contaminating proteins released from dead cells or derived from cell medium. To reduce the likelihood of contaminations we applied an approach combining secretome and proteome analysis to characterize the physiological secretome of BM derived human MSC. Our analysis revealed a secretome consisting of 315 proteins. Pathway analyses of these proteins revealed a high abundance of proteins related to cell growth and/or maintenance, signal transduction and cell communication thereby representing key biological functions of BM derived MSC on protein level. Within the MSC secretome we identified several cytokines and growth factors such as VEGFC, TGF-β1, TGF-β2 and GDF6 which are known to be involved in the physiological regulation of hematopoiesis. By comparing the peptide patterns of secretomes and cell lysates 17 proteins were identified as candidates for proteolytic processing. Taken together, our combined MS work-flow reduced the likelihood of contaminations and enabled us to carve out a specific overview about the composition of the secretome from human BM derived MSC. This methodological approach and the specific secretome signature of BM derived MSC may serve as basis foffuture comparative analyses of the interplay of MSC and HSPC in patients with hematological malignancies.
