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:Mesenchymal stromal cells (MSCs) derived from bone marrow (BM) have stronger potential for endochondral ossification compared to white adipose tissue (WAT)-MSCs, umbilical cord (UC)-MSCs, and skin fibroblasts (FB). We assessed uniquely accessible enhancers facilitating bone regeneration potential.
Project description:Mesenchymal stromal cells (MSCs) derived from bone marrow (BM) have stronger potential for endochondral ossification compared to white adipose tissue (WAT)-MSCs, umbilical cord (UC)-MSCs, chondrocytes (CH) and skin fibroblasts (FB). We assessed active regulatory regions facilitating bone-regeneration potential.
Project description:Expression analysis of migrating and non-migrating mesenchymal stromal cells (MSC) in fetal bone marrow Keywords: fetal bone marrow, mesenchymal stromal cells, migration, gene expression, genomics Three biological replates for both migrating and non-migrating mesenchymal stromal cells (MSC) in fetal bone marrow
Project description:Fibrocytes from human peripheral blood mononuclear cells were isolated using the vacutainer method and allowed to differentiate under cultured conditions for 14 days with harvesting occuring at days 0, 1, 7, and 14. Fibrocytes isolated using the lysis method were differentiated and collected on day 14. The following cell types related to fibrocytes were additionally analyzed: bone marrow-derived mesenchymal stromal cells, dermal fibroblasts, and human vocal fold fibroblasts
Project description:Isolated mesenchymal stromal cells (MSC) were obtained from either adipose or bone marrow from rat and sheep. Human MSC were purchased from Lonza. All MSC were expanded on tissue culture plastic in standard culture conditions.
Project description:To characterize and compare XF-iMSC (XenoFree-induced Mesenchymal stem/stromal cells) and various types of MSCs (Adipose-, Bone marrow-, Unbilical cord-derived), we performed a transcriptome analysis of these MSCs
Project description:Adipose-derived mesenchymal stromal cells from subcutaneous (n=4) and visceral (n=4) tissue, along with dermal fibroblasts (n=3) were analyzed by single-cell RNA sequencing.
