BACKGROUND: The combination of autologous mesenchymal stem cells (MSCs) and cardiac stem cells (CSCs) synergistically reduces scar size and improves cardiac function in ischemic cardiomyopathy. Whereas allogeneic (allo-)MSCs are immunoevasive, the capacity of CSCs to similarly elude the immune system remains controversial, potentially limiting the success of allogeneic cell combination therapy (ACCT). OBJECTIVES: This study sought to test the hypothesis that ACCT synergistically promotes cardiac regeneration without provoking immunologic reactions...

Hypoxia treatment enhances paracrine effect of mesenchymal stem cells (MSCs). The aim of this study was to investigate whether exosomes from hypoxia-treated MSCs (Exo(H)) are superior to those from normoxia-treated MSCs (Exo(N)) for myocardial repair. Mouse bone marrow-derived MSCs were cultured under hypoxia or normoxia for 24 h, and exosomes from conditioned media were intramyocardially injected into infarcted heart of C57BL/6 mouse. Exo(H) resulted in significantly higher survival, smaller scar size and better cardiac functions recovery...

Previous studies of the authors have indicated that the transplantation of mesenchymal stem cells (MSCs) can attenuate cardiac fibrosis through the secretion of antifibrotic factors, such as adrenomedullin (ADM). Therefore, the authors addressed the hypothesis that ADM overexpression could enhance the antifibrotic effect of MSCs transplantation in a rat model of heart failure. The results of the present study demonstrated that, compared with the group that received the GFP‑MSCs, the transplantation of ADM‑MSCs significantly improved heart function and decreased the percentage of fibrotic area and the expression of matrix metalloproteinase 2...

The aim was to evaluate the tadalafil-mediated effects at molecular level on bone marrow-derived mesenchymal stem cells (MSCs) survival and their homing into the infarcted hearts to promote cardiac repair and improve function. MSCs were pretreated in vitro with inhibitors of PKG, MAPK, FasL, nitric oxide synthase (NOS) (L-NAME), CXCR4 (AMD3100), or miR-21 inhibitors (+/-luciferase construction +/-Fas) prior to tadalafil treatment for 2 h. These MSCs were then subjected to H2O2 stress to assess their injury...

Pulmonary hypertension is a critical problem in infants with bronchopulmonary dysplasia. This study determined the therapeutic effects of human mesenchymal stem cells (MSCs) on pulmonary hypertension in an animal model. Pregnant Sprague-Dawley rats were intraperitoneally injected with lipopolysaccharide (LPS, 0.5 mg/kg/day) on gestational days 20 and 21. The pups were randomly assigned to two treatment conditions: room air (RA) or an O2-enriched atmosphere. On postnatal day 5, they were intratracheally transplanted with human MSCs (3 × 10(5) and 1 × 10(6) cells) in 0...

To date, a completely in vitro repopulated tissue-engineered heart valve has not been developed. This study focused on sequentially seeding 2 cell populations onto porcine decellularized heart valve leaflets (HVL) and pericardia (PER) to obtain fully repopulated tissues. For repopulation of the interstitium, porcine valvular interstitial cells (VIC) and bone marrow-derived mesenchymal stem cells (BM-MSC) or adipose tissue-derived stem cells (ADSC) were used. In parallel, the culture medium was supplemented with ascorbic acid 2-phosphate (AA) and its effect on recolonization was investigated...

Dilated cardiomyopathy (DCM) is a disease of the heart characterized by pathological remodeling, including patchy interstitial fibrosis and degeneration of cardiomyocytes. In the present study, the beneficial role of human umbilical cord‑derived mesenchymal stem cells (HuMSCs) derived from Wharton's jelly was evaluated in the myosin‑induced rat model of DCM. Male Lewis rats (aged 8‑weeks) were injected with porcine myosin to induce DCM. Cultured HuMSCs (1x106 cells/rat) were intravenously injected 28 days after myosin injection and the effects on myocardial fibrosis and the underlying signaling pathways were investigated and compared with vehicle‑injected and negative control rats...

Adipose-tissue derived mesenchymal stem cell (ADSC)-based therapy is a promising option for patients with atherosclerotic conditions, including coronary artery disease. However, the potential differences in the metabolic characteristics between bone marrow-derived mesenchymal stem cells (BMSCs) and ADSCs have remained to be fully elucidated. The present study aimed to compare the metabolic profiles of BMSCs and ADSCs via liquid chromatography quadrupole time-of-flight mass spectrometry. BMSCs and ADSCs obtained from elderly coronary heart disease patients were cultured, and after three passages, supernatants of each cell type were collected and systematically analysed...

Mesenchymal stem cells (MSCs) are multipotent stromal cells that merit the differentiation into various cell types. The present study was designed to test the hypothesis that the cardioprotective effect of MSCs transplantation and digoxin treatment is mediated via the regulation of messenger RNA gene expression of pro-inflammatory cytokines and apoptotic markers. Myocardial infarction was induced in Wistar rats via isoproterenol injection in a dose of (85 mg/kg, subcutaneously, twice at an interval of 24 h)...

Using an innovative, tissue-independent approach to decellularized tissue processing and biomaterial fabrication, the development of a series of "tissue papers" derived from native porcine tissues/organs (heart, kidney, liver, muscle), native bovine tissue/organ (ovary and uterus), and purified bovine Achilles tendon collagen as a control from decellularized extracellular matrix particle ink suspensions cast into molds is described. Each tissue paper type has distinct microstructural characteristics as well as physical and mechanical properties, is capable of absorbing up to 300% of its own weight in liquid, and remains mechanically robust (E = 1-18 MPa) when hydrated; permitting it to be cut, rolled, folded, and sutured, as needed...

BACKGROUND: Diabetes mellitus is a risk factor for coronary artery disease and diabetic cardiomyopathy, and adversely impacts outcomes following coronary artery bypass grafting. Current treatments focus on macro-revascularization and neglect the microvascular disease typical of diabetes mellitus-induced cardiomyopathy (DMCM). We hypothesized that engineered smooth muscle cell (SMC)-endothelial progenitor cell (EPC) bi-level cell sheets could improve ventricular dysfunction in DMCM. METHODS: Primary mesenchymal stem cells (MSCs) and EPCs were isolated from the bone marrow of Wistar rats, and MSCs were differentiated into SMCs by culturing on a fibronectin-coated dish...

For years, sufficient progress has been made in treating heart failure following myocardial infarction; however, the social and economic burdens and the costs to world health systems remain high. Moreover, treatment advances have not resolved the underlying problem of functional heart tissue loss. In this field of research, for years we have actively explored innovative biotherapies for cardiac repair. Here, we present a general, critical overview of our experience in using mesenchymal stem cells, derived from cardiac adipose tissue and umbilical cord blood, in a variety of cell therapy and tissue engineering approaches...

BACKGROUND/PURPOSE: Cardiac mesenchymal stem cells (MSCs) could stimulate cell-specific regenerative mechanisms after myocardial infarction (MI) depending on spatial origin, distribution, and niche regulation. We aimed at identifying and isolating tissue-specific cardiac MSCs that could contribute to regeneration. METHODS: Following permanent ligation of the left anterior descending coronary artery in rats (n = 16), early cardiac tissues and cardiac mononuclear cells (MNCs) were analyzed by immunohistology, confocal laser scanning microscopy, and flow cytometry, respectively...

The envisioned routine application of human pluripotent stem cell (hPSC)-derived cardiomyocytes (CMs) for therapies and industry-compliant screening approaches will require efficient and highly reproducible processes for the mass production of well-characterized CM batches.On their way toward beating CMs, hPSCs initially undergo an epithelial-to-mesenchymal transition into a primitive-streak (PS)-like population that later gives rise to all endodermal and mesodermal lineages, including cardiovascular progenies (CVPs)...

Mesenchymal stem cells (MSCs) are attractive tools for regenerative medicine because of their multi-differentiation potential and immunomodulation capacity. In congenital heart defect surgical correction, replacement grafts lacking growth potential are commonly used. Tissue engineering promises to overcome the limitations of these grafts. In this study, we hypothesized that human thymus derived MSCs are a suitable tool to tissue engineer a living vascular graft with good integration and patency once implanted in vivo...

The poor survival of cells in ischemic sites diminishes the therapeutic efficacy of stem cell therapy. Previously we and others have reported that Cannabinoid receptor type II (CB2) is protective during heart ischemic injury for its anti-oxidative activity. However, whether CB2 activation could improve the survival and therapeutic efficacy of stem cells in ischemic myocardium and the underlying mechanisms remain elusive. Here, we showed evidence that CB2 agonist AM1241 treatment could improve the functional survival of adipose-derived mesenchymal stem cells (AD-MSCs) in vitro as well as in vivo...

Background -Cell therapy remains the most promising approach against ischemic heart injury. However, the poor survival of engrafted stem cells in the ischemic environment limits their therapeutic efficacy for cardiac repair post myocardial infarction (MI). C1q/tumor necrosis factor-related protein-9 (CTRP9) is a novel pro-survival cardiokine with significantly downregulated expression after MI. Here, we tested a hypothesis that CTRP9 might be a cardiokine required for a healthy microenvironment promoting implanted stem cell survival and cardioprotection...
