Transcription profiling of human mesenchymal stem cells (six batches)

ABSTRACT: Human mesenchymal stem cells (hMSCs), which are multipotent cells to differentiate into several cell types, are expected to be a useful tool for cellular therapy. In some clinical settings, hMSCs have immuno-suppressive effects for GVHD (Graft-versus-host disease) and are expanded in vitro before application. To find biomarkers that indicate the culture stage of hMSCs, we performed microarray analysis for hMSCs derived from bone marrow, using Affymetrix GeneChip Human Genome U133 Plus 2.0 (54,613 probe sets). Experiment Overall Design: We profiled the gene expression in 6 different batches of hMSCs. The cells were cultured and subjected to total RNA extraction. We performed microarray analysis using 6 batches provided by 6 different individuals in early stage (passage #4 or 5), middle stage (#7 or 9) or senescing stage (#22, 24, or 28).

Cell senescence abrogates the immunomodulatory therapeutic potential of human mesenchymal stem cells

Project description:In this study, we have addressed how cellular senescence influences the immunomodulatory potential of human mesenchymal stem cells (hMSCs). We induced cell senescence in a panel of bone marrow-derived hMSC samples by means of gamma-irradiation, and performed both gene expression and miRNA microarray analyses on the untreated and senescent samples. We also compared the gene expression profile of untreated and senescent hMSCs with those obtained from several hMSCs samples used in an ongoing allogeneic clinical study of Graft Versus Host Disease (GVHD), of which their therapeutic efficacy is known. We have identified several genes (PLEC, C8orf48, TRPC4, and ZNF14) differentially expressed in senescent hMSCs that are similarly regulated in hMSC samples that did not show a therapeutic effect in the GVHD study. These genes might be useful as markers to evaluate the therapeutic potential of hMSCs used in future clinical studies. We compared the gene and miRNA expression profiles of untreated (WT) control bone marrow-derived hMSCs with the same primary cell lines 10 days after gamma-irradiation (SEN) and with several hMSCs samples used in a clinical stydy of GVHD. The samples used in the clinical study were classified in two groups, depending on whether they elicited a therapeutic response (G1) or not (G2). A total of four independent samples (biological replicates) were used for WT and SEN conditions. For the samples used in the clinical study, a total of five samples were used for the G1 group, and three samples for the G2 group.

Gene Expression Profiles of PBMC Subsets in Acute GVHD Following Cord Blood Transplantation (IMS v.2)

Project description:In comparison with allogeneic hematopoietic stem cell transplantation using other sources, umbilical cord blood transplantation (UCBT) offers substantial clinical advantages including a lower incidence and severity of acute graft-versus-host disease (GVHD) despite the use of allogeneic UCB stem cells with more disparate HLA. However, detailed pathophysiology of acute GVHD developed after UCBT has not yet been clarified. Here, we examined the roles of inflammatory cells in the pathogenesis of acute GVHD following UCBT, by expression profiling of a total of 615 genes in each of 4 subsets (CD4+, CD8+, CD14+, and CD56+) of peripheral blood mononuclear cells (PBMCs), which were taken from 5 patients with hematologic malignancy, in whom acute GVHD had developed after UCBT. By comparing expression profiles measured during acute GVHD with those measured upon discharge (recovery phase), for each subset of PBMCs, we identified immuno-regulatory genes which were assumed to be linked to the pathogenesis of acute GVHD. Keywords: disease state analysis CD4+, CD8+, CD14+, and CD56+ cell subsets were isolated from the peripheral blood mononuclear cells (PBMCs) of 5 patients with hematologic malignancy, in whom acute GVHD had developed after cord blood transplantation. PBMCs were taken twice â during acute GVHD phase and upon discharge (recovery phase), from each patient. By using a custom-made fibrous oligonucleotide DNA microarray Genopal (Mitsubishi Rayon), we compared expression profiles of 615 unique genes measured during acute GVHD with those measured upon discharge (recovery phase), for each subset of PBMCs.

However, detailed pathophysiology of acute GVHD developed after UCBT has not yet been clarified. Here, we examined the roles of inflammatory cells in the pathogenesis of acute GVHD following UCBT, by expression profiling of a total of 595 genes in each of 4 subsets (CD4+, CD8+, CD14+, and CD56+) of peripheral blood mononuclear cells (PBMCs), which were taken from 3 patients with hematologic malignancy, in whom acute GVHD had developed after UCBT. We compared expression profiles measured during acute GVHD with those measured opon discharge (recovery phase), for each subset of PBMCs to identify immuno-regulatory genes which were assumed to be linked to the pathogenesis of acute GVHD. Keywords: disease state analysis Peripheral blood mononuclear cells (PBMCs) were taken from 3 patients with hematologic malignancy, in whom acute GVHD had developed after cord blood transplantation. CD4+, CD8+, CD14+, and CD56+ cell subsets were isolated from the PBMCs of 2 patients, while only CD8+ and CD56+ cell subsets were isolated from the PBMCs of a patient. PBMCs were taken twice - during acute GVHD phase and upon discharge (recovery phase), from each patient. By using a custom-made fibrous oligonucleotide DNA microarray Genopal (Mitsubishi Rayon), we compared expression profiles of 595 unique genes measured during acute GVHD with those measured upon discharge (recovery phase), for each subset of PBMCs.

RNA-Seq of lymph node fibroblastic reticular cells isolated from bone marrow transplant recipient mice with or without acute Graft-versus-host disease on day 7 or untransplanted control mice

Project description:Acute GVHD is known to damage the structure of peripheral lymphoid organs. This study investigates how peripheral tolerance induction is affected by lymph node stroma damage in the context of graft-versus-host disease. Fibroblastic reticular cells (FRC) were flow sorted on day 7 post allo-BMT in mice developing acute GVHD, transplanted no GVHD-recipients or untransplanted control mice. The single miHA-mismatch female into male transplantation model was used (acute GVHD group: T-cell depleted bone marrow (TCDBM) + HY-specific TCR-transgenic MataHari CD8+ T cells into C57BL/6 male recipients; no GVHD group: TCDBM only).

Tc17 cells are a pro-inflammatory, plastic lineage of pathogenic CD8+ T-cells that induce GVHD without anti-leukemic effects

Project description:IL-17-producing cells are important mediators of graft-versus-host disease (GVHD) after allogeneic stem cell transplantation (SCT). Here we demonstrate that a distinct CD8+ Tc17 population develops rapidly after SCT but fails to maintain lineage fidelity such that they are unrecognizable in the absence of a fate reporter. Tc17 differentiation is dependent on alloantigen presentation by host-DC together with IL-6. Tc17 cells express high levels of multiple prototypic lineage-defining transcription factors (e.g. RORgt, T-bet) and cytokines (e.g. IL-17A, IL-22, IFNg, GM-CSF, IL-13). Targeted depletion of Tc17 early after transplant protects from lethal acute GVHD, however Tc17 cells are non-cytolytic and fail to mediate graft–versus–leukemia (GVL) effects. Thus, the Tc17 differentiation program during GVHD culminates in a highly plastic, hyper-inflammatory, poorly-cytolytic effector population which we term inflammatory Tc17 (iTc17). Since iTc17 mediate GVHD without contributing to GVL, therapeutic inhibition of iTc17 development in a clinical setting represents an attractive approach for separating GVHD and GVL.
