Cell Death Discov 2019; 5:78. [PMID: 30911412 PMCID: PMC6423043 DOI: 10.1038/s41420-019-0161-y] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2019] [Revised: 02/22/2019] [Accepted: 03/04/2019] [Indexed: 12/19/2022] Open
Abstract
Cyclic helix B peptide (CHBP) is a peptide derivant of erythropoietin with powerful tissue-protective efficacies in a variety of organ injuries, but without erythropoietic effect. However, the role of CHBP in acute myocardial infarction (AMI) and related mechanisms are not studied yet. In this study, we found in a murine AMI model that the administration of CHBP could ameliorate cardiac injury, increase the survival rate, inhibit cardiomyocyte apoptosis, improve cardiac function and remodeling, and reduce the expression of inflammatory cytokines in the serum and kidney tissue both at 24 h and 8 weeks following AMI. This study suggests that CHBP has the potential to be used as an effective drug in the treatment of AMI.

Combined Analysis of Endothelial, Hematopoietic, and Mesenchymal Stem Cell Compartments Shows Simultaneous but Independent Effects of Age and Heart Disease. Stem Cells Int 2017; 2017:5237634. [PMID: 28819363 PMCID: PMC5551513 DOI: 10.1155/2017/5237634] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2017] [Revised: 05/24/2017] [Accepted: 06/06/2017] [Indexed: 12/22/2022] Open
Abstract
Clinical trials using stem cell therapy for heart diseases have not reproduced the initial positive results obtained with animal models. This might be explained by a decreased regenerative capacity of stem cells collected from the patients. This work aimed at the simultaneous investigation of endothelial stem/progenitor cells (EPCs), mesenchymal stem/progenitor cells (MSCs), and hematopoietic stem/progenitor cells (HSCs) in sternal bone marrow samples of patients with ischemic or valvular heart disease, using flow cytometry and colony assays. The study included 36 patients referred for coronary artery bypass grafting or valve replacement surgery. A decreased frequency of stem cells was observed in both groups of patients. Left ventricular dysfunction, diabetes, and intermediate risk in EuroSCORE and SYNTAX score were associated with lower EPCs frequency, and the use of aspirin and β-blockers correlated with a higher frequency of HSCs and EPCs, respectively. Most importantly, the distribution of frequencies in the three stem cell compartments showed independent patterns. The combined investigation of the three stem cell compartments in patients with cardiovascular diseases showed that they are independently affected by the disease, suggesting the investigation of prognostic factors that may be used to determine when autologous stem cells may be used in cell therapy.

Cytotherapy 2015; 17:1365-73. [PMID: 26166321 DOI: 10.1016/j.jcyt.2015.05.003] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2015] [Revised: 05/09/2015] [Accepted: 05/11/2015] [Indexed: 12/17/2022]
Abstract
BACKGROUND AIMS The purpose of the study was to investigate the feasibility of in vitro and in vivo bioluminescence imaging (BLI), fluorescence imaging (FI) and magnetic resonance imaging (MRI) to trace transplanted bone mesenchymal stromal cells (BMSCs) labeled with the firefly luciferase (Fluc) reporter gene, CyI dyes and ultra-small super-paramagnetic iron oxide (USPIO) particles. METHODS Fluc-transfected BMSCs were further labeled with CyI dyes and USPIO particles, respectively. Acute myocardial infarction models of different weighted Sprague-Dawley rats and Balb/c mice were established, and BLI and FI were performed in vivo and ex vivo to determine the optimal method of optical imaging. Finally, BLI and MRI were selected to trace transplanted BMSCs in a murine model in vivo. RESULTS BLI was found to be the optimal optical imaging method in vivo, compared with FI, and mice were found to be the optimal animal model, compared with rats. A significant BLI signal intensity was detected in the heart region in the BMSC-treated mice group (40,552 ± 6073 counts, n = 26) and gradually decreased below the detection threshold. Two distinct hypo-intense regions were observed in the anterior wall of the heart, where stem cells were injected on MR images obtained with the gradient recalled echo cine sequence in the BMSC-treated mice group. CONCLUSIONS Transplanted BMSCs labeled with Fluc reporter gene and USPIO particles can be traced with the use of BLI and MRI in a mouse model of acute myocardial infarction.
