Comprehensive transcriptomic and proteomic characterization of human mesenchymal stem cells reveals source specific cellular markers

ABSTRACT: Mesenchymal stem cells (MSC) are multipotent cells with great potential in therapy, reflected by more than 500 MSC-based clinical trials registered with the NIH. MSC are derived from multiple tissues but require invasive harvesting and imply donor-to-donor variability. Embryonic stem cell-derived MSC (ESC-MSC) may provide an alternative, but how similar they are to ex vivo MSC is not known. Here we performed an in depth characterization of human ESC-MSC, comparing them to human bone marrow-derived MSC (BM-MSC) as well as hESC by transcriptomics (RNA-Seq) and quantitative proteomics (nano LC-MS/MS using SILAC). Data integration highlighted and validated a central role of vesicle-mediated transport and exosomes in MSC biology and also demonstrated, through enrichment analysis, their versatility and broad application potential. A particular emphasis was placed on comparing profiles between ESC-MSC and BM-MSC and assessing their equivalency. Data presented here shows that differences between ESC-MSC and BM-MSC are similar in magnitude to those reported for MSC of different origin and the former may thus represent an alternative source for therapeutic applications. Finally, we report an unprecedented coverage of MSC CD markers, as well as membrane associated proteins which may benefit immunofluorescence-based applications and contribute to a refined molecular description of MSC.

Project description:Cyclic regeneration of the endometrium, and its repair after parturition or injury, are crucial for successful reproduction. Mesenchymal stem cells (MSCs) derived from bone marrow (BM-MSC) facilitate tissue repair via their secretome, which contains growth factors and cytokines that promote wound healing. Despite the implication of MSCs in endometrial regeneration and repair, the mechanisms remain unclear. This study tested the hypothesis that the secretome of MSCs from human BM upregulates human endometrial stromal cell (HESC) proliferation, migration and invasion, and activates pathways to increase HESC motility. MSCs were purchased from ATCC (BM-MSC-1) and cultured from the BM aspirate of a healthy female donor (BM-MSC-2). Indirect co-culture of MSCs and hTERT-immortalized HESCs via a transwell system studied the effect of the BM-MSC secretome on HESC proliferation, migration, and invasion. To study the effect of the MSC secretome on HESC gene expression, HESCs were exposed to the BM-MSC secretome via indirect co-culture for 24 h. Total RNA was extracted from HESCs for RNA sequencing (RNA-Seq). Differentially expressed genes (DEG) and significantly altered pathways were identified. Indirect co-culture of HESCs with BM- MSCs resulted in significant increase in HESC migration and invasion regardless of the source of MSCs. Effects on cellular proliferation varied among the BM-MSC source. Exposure of HESCs to the secretome of BM-MSCs changed the expression of 10,141 genes with FDR < 0.05. There was overlap among 4351 genes between HESCs exposed to BM-MSC-1 and BM-MSC-2, including upregulated expression of cell motility genes common to both BM-MSC exposures. Increased HESC motility by the secretome of BM-MSC appears to be mediated by paracrine and autocrine mechanisms, in part by modifying HESC gene expression. These data support the potential for leveraging the MSC secretome as a novel cell-free therapy in the treatment of disorders of endometrial regeneration.

Project description:Background: Systemic sclerosis (SSc) is a chronic autoimmune disease. We tested the safety of a single intravenous injection of intrafamilial allogeneic bone marrow-derived mesenchymal stromal cells (BM-MSC) to treat severe SSc. Methods: We conducted the first prospective, monocentric, dose-escalation, phase I/II clinical trial investigating the feasibility and safety of a single allogeneic BM-MSC infusion in 20 severe SSc patients who were refractory or had a contraindication to conventional immunosuppressive therapy or autologous hematopoietic stem cell transplant. Patients were assigned to an infusion of either 1x10^6 BM-MSC/kg or 3x10^6 BM-MSC/kg obtained from 20 independent intrafamilial donors. Primary endpoint was the rate of grade ≥ 3 Severe Adverse Events (SAE; NCI Common Terminology Criteria for Adverse Events (v5.0)) in the first 10 days post-BM-MSC infusion. Secondary endpoints included adequacy of BM-MSC production, medium-term SAE, as well as clinical and immunological response. Findings: No Grade 3 ≥ SAE occurred in the first 10 days following MSC infusion in the 20 SSc patients. A significant improvement in modified Rodnan Skin Score (p<0.0001) was observed after BM-MSC infusion, which peaked at 3 months and was sustained for 1 year. No changes in health-related quality of life or pulmonary function were observed. CD8pos T-Cell and NK cell counts slightly increased after infusion (p<0.05) and two patients developed de novo donor-specific anti-HLA. Circulating TGF-β level at baseline was significantly higher in non-responder compared to responder patients (p<0.05). A pattern of low IDO activity, CCL2 production, and HLA-DR expression in BM-MSC batches under in vitro stimulation by IFN-beta was associated with a lack of clinical response in recipient SSc patients. Interpretation: A single infusion of allogeneic BM-MSC transplant was safe in severe SSc patients and triggered short-term disease modifying effects. Clinical response was associated with both the recipients biological features and the functional properties of infused BM-MSC.
