Characterization of canine mesenchymal stromal cell lines (MSC)

ABSTRACT: The bone marrow microenvironment is a complex mixture of cells that function in concert to regulate hematopoiesis. Cellular components include fixed nonhematopoietic stromal elements (MSC) as well as monocytes and resident macrophages, which are derived from the hematopoietic stem cells. Clinical studies have shown healing effects, direct or indirect, from the injection of MSC int Keywords: Cell type comparison

Characterization of canine mesenchymal stromal cell lines (MSC)

Project description:The bone marrow microenvironment is a complex mixture of cells that function in concert to regulate hematopoiesis. Cellular components include fixed nonhematopoietic stromal elements (MSC) as well as monocytes and resident macrophages, which are derived from the hematopoietic stem cells. Clinical studies have shown healing effects, direct or indirect, from the injection of MSC int Keywords: Cell type comparison Canine bone marrow stromal cells were immortalized by transduction with a replication-defective recombinant retrovirus containing the human papilloma virus E6/E7 genes (pLXSN-16 E6E7), as described for human stromal cell lines in Roecklein and Torok-Storb (Blood 85:997-1005, 1995). Transduced clones were selected with 50 ug/ml G418 and resistant clones were isolated, grown to confluency and characterized for morphology, cytokine production and cell surface molecule expression. These cells are intended for clinical research in the canine transplantation model, as a complement for existing human stromal cell lines, for mitigation of graft-versus-host disease and radiation effects.

Transcription profiling of human monocytes grown in CM from functionallu distinct cell lines HS5 and HS27a

Project description:The bone marrow microenvironment is a complex mixture of cells that function in concert to regulate hematopoiesis. Cellular components include fixed nonhematopoietic stromal elements as well as monocytes and resident macrophages, which are derived from the hematopoietic stem cells. Although these monocyte-lineage cells are reported to modify stromal cell function, the reverse also occurs. Given the secretory capability of the monocyte/macrophage and their various potential functions, it is not surprising that stromal cells contained within a particular niche can modify monocyte gene expression and functional maturation. Experiment Overall Design: Monocytes were isolated from peripheral blood mononuclear cells from 2 different normal donors and cultured for 48h in conditioned medium (CM). The CM was collected from each of two functionally distinct human bone marrow stromal cell lines (HS5 and HS27a) representing different compartments of the bone marrow microenvironment (Roecklein BA, Torok-Storb B. Blood. 1995;85:997-1005). Four samples were analyzed, with two biological replicates for each CM.

Exosomes from MSC facilitate diabetic wound healing by promoting angiogenesis

Project description:Mesenchymal stem cell (MSC)-derived exosomes had been reported to be a prospective candidate in accelerating diabetic wound healing. Hence, this study intended to explore whether exosomes originating from the human umbilical cord MSC (hucMSC) could display a superior proangiogenic effect on diabetic wound repair and its underlying molecular mechanism.

Effect of MSC and MSC-derived extracellular vesicles on human blood coagulation

Project description:Mesenchymal stem cells (MSC) have emerged as potent therapeutic tool for a number of pathologies, including immune ones. However, unwelcome effects of MSC on the blood coagulation were revealed in some cases, which require more in-depth analysis. In this study, we explored the trombotic properties of human MSC from umbilical cord. We revealed strong procoagulant effects of umbilical cord MSC toward human and rat whole blood and platelets-free plasma using rotational thromboelastometry and thrombodynamics tests. The similar potentiation of clotting was demonstrated for MSC-derived extracellular vesicles (EV). In order to suggest approaches to avoid unwanted effects we studied the impact of heparin supplement on MSC/EV procoagulation properties. We found that therapeutic doses of unfractionated heparin injected in the patient's blood (administered in vivo) did not abrogate the procoagulant properties of MSC. Mass-spectrometry analysis of proteins of MSC and EV involved in coagulation-associated pathways was used to evaluate mechanisms of protrombotic effects.

Comparison of transciptome of hiPS-MSC versus MSC (2D culture) and analyze regulated trascripts during differentiation of hiPS-MSC and MSC on a 3D scaffold

Project description:Expression data from hiPS lines after commitment towards mesenchymal lineage (hiPS-MSC) and expression data of mesenchymal lines (MSC), used as positive control of commitment. Following this, hiPS-MSC and MSC are seeded on scaffold to differentiate in a ligamentous (middle) and osseous (edges) part (post 21 days 3D differentiation) We used microarrays to validate efficient commitment of hiPS to generate hiPS-MSC and do whole transcriptome comparison of hiPS-MSC vs isolated MSC (positive control) and then compare the enhanced biological functions after differentiation of these cells on a scaffold

Quantitative proteomic characterization of lung-MSC and bone marrow-MSC using DIA-mass spectrometry

Project description:Mesenchymal stromal cells (MSC) are ideal candidates for cell therapies, due to their immune-regulatory and regenerative properties. We have previously reported that lung-derived MSC are tissue-resident cells with lung-specific properties compared to bone marrow-derived MSC. Assessing relevant molecular differences between lung-MSC and bone marrow-MSC is important, given that such differences may impact their behavior and potential therapeutic use. Here, we present an in-depth mass spectrometry (MS) based strategy to investigate the proteomes of lung-MSC and bone marrow-MSC. The MS-strategy relies on label free quantitative data-independent acquisition (DIA) analysis and targeted data analysis using a MSC specific spectral library. We identified several significantly differentially expressed proteins between lung-MSC and bone marrow-MSC within the cell layer (352 proteins) and in the conditioned medium (49 proteins). Bioinformatics analysis revealed differences in regulation of cell proliferation, which was functionally confirmed by decreasing proliferation rate through Cytochrome P450 stimulation. Our study reveals important tissue-specific differences within proteome and matrisome profiles between lung- and bone marrow-derived MSC that may influence their behavior and affect the clinical outcome when used for cell-therapy.
