Abstract
We review the evidence for the presence of stem/progenitor cells in the heart and the preclinical and clinical data using diverse cell types for the therapy of cardiac diseases. We highlight the failure of adult stem/progenitor cells to ameliorate heart function in most cardiac diseases, with the possible exception of refractory angina. The use of pluripotent stem cell-derived cardiomyocytes is analysed as a viable alternative therapeutic option but still needs further research at preclinical and clinical stages. We also discuss the use of direct reprogramming of cardiac fibroblasts into cardiomyocytes and the use of extracellular vesicles as therapeutic agents in ischemic and non-ischemic cardiac diseases. Finally, gene therapies and genome editing for the treatment of hereditary cardiac diseases, ablation of genes responsible for atherosclerotic disease, or modulation of gene expression in the heart are discussed.

Abstract
Cardiovascular diseases represent the world’s leading cause of death. In this heterogeneous group of diseases, ischemic cardiomyopathies are the most devastating and prevalent, estimated to cause 17.9 million deaths per year. Despite all biomedical efforts, there are no effective treatments that can replace the myocytes lost during an ischemic event or progression of the disease to heart failure. In this context, cell therapy is an emerging therapeutic alternative to treat cardiovascular diseases by cell administration, aimed at cardiac regeneration and repair. In this review, we will cover more than 30 years of cell therapy in cardiology, presenting the main milestones and drawbacks in the field and signaling future challenges and perspectives. The outcomes of cardiac cell therapies are discussed in three distinct aspects: The search for remuscularization by replacement of lost cells by exogenous adult cells, the endogenous stem cell era, which pursued the isolation of a progenitor with the ability to induce heart repair, and the utilization of pluripotent stem cells as a rich and reliable source of cardiomyocytes. Acellular therapies using cell derivatives, such as microvesicles and exosomes, are presented as a promising cell-free therapeutic alternative.

Abstract
The BMI1 protein, a member of the PRC1 family, is a well recognised transcriptional suppressor and has the capability of maintaining the self-renewal and proliferation of tissue-specific stem cells. Numerous studies have established that BMI1 is highly expressed in a variety of malignant cancers and serves as a key regulator in the tumorigenesis process. However, our understanding of BMI1 in terminally differentiated organs, such as the heart, is relatively nascent. Importantly, emerging data support that, beyond the tumor, BMI1 is also expressed in the heart tissue and indeed exerts profound effects in various cardiac pathological conditions. This review gives a summary of the novel functions of BMI1 in the heart, including BMI1-positive cardiac stem cells and BMI1-mediated signaling pathways, which are involved in the response to various cardiac pathological stimuli. Besides, we summarize the recent progress of BMI1 in some novel and rapidly developing cardiovascular therapies. Furtherly, we highlight the properties of BMI1, a therapeutic target proved effective in cancer treatment, as a promising target to alleviate cardiovascular diseases.

Abstract
Cardiovascular disease remains the primary cause of death in the United States and in most nations worldwide, despite ongoing intensive efforts to promote cardiac health and treat heart failure. Replacing damaged myocardium represents perhaps the most promising treatment strategy, but also the most challenging given that the adult mammalian heart is notoriously resistant to endogenous repair. Cardiac regeneration following pathologic challenge would require proliferation of surviving tissue, expansion and differentiation of resident progenitors, or transdifferentiation of exogenously applied progenitor cells into functioning myocardium. Adult cardiomyocyte proliferation has been the focus of investigation for decades, recently enjoying a renaissance of interest as a therapeutic strategy for reversing cardiomyocyte loss due in large part to ongoing controversies and frustrations with myocardial cell therapy outcomes. The promise of cardiac cell therapy originated with reports of resident adult cardiac stem cells that could be isolated, expanded and reintroduced into damaged myocardium, producing beneficial effects in preclinical animal models. Despite modest functional improvements, Phase I clinical trials using autologous cardiac derived cells have proven safe and effective, setting the stage for an ongoing multi-center Phase II trial combining autologous cardiac stem cell types to enhance beneficial effects. This overview will examine the history of these two approaches for promoting cardiac repair and attempt to provide context for current and future directions in cardiac regenerative research.

Abstract
OBJECTIVE To evaluate the effects of miR-210 on cardiac stem cells (CSCs) against hypoxia-induced injury. METHODS CSCs were isolated from rat ventricular wall and cultured until passage 4. After exposure to hypoxia for 6 h, the expression of miR-210 was determined. Thereafter, transfection of miR-210 mimic and inhibitor was carried out. 1 week later, in vitro experiments were performed to measure the expression of caspase-8-associated protein 2 (Casp8ap2), Caspase 8, protein tyrosine phosphatase, non-receptor type 2 (PTPN2) and CXC chemokine receptor 4 (CXCR4), as well as migration and apoptosis of CSCs under hypoxic condition. RESULTS Hypoxia induced a significant up-regulation of miR-210 expression in CSCs. Notably, the expression of Casp8ap2, Caspase8, PTPN2 was dramatically inhibited by overexpression of miR-210 in CSCsmiR-210 Group (P < .05), but no changes in CXCR4 (P > .05), compared with the control. Additionally, a decreased apoptosis of CSCs was detected in CSCsmiR-210 Group (26.22 ± 1.15%, P < .001), compared with Control Group (34.97 ± 0.63%). Moreover, the migration of CSCs was significantly promoted in CSCsmiR-210 Group (45.73 ± 2.4, P < .001), compared with Control Group (19.6 ± 1.11). Meanwhile, down-regulation of miR-210 reversed these results (P < .05). CONCLUSIONS miR-210 was a hypoxia responsive element in CSCs, and its up-regulation inhibited apoptosis of CSCs and promoted their migration under hypoxic condition, through regulating its target genes Casp8ap2/Caspase 8 and PTPN2, which may provide a new strategy for cell therapy of ischemic heart disease.

Abstract
Hypoxia is beneficial for the differentiation of stem cells transplanted for myocardial injury, but mechanisms underlying this benefit remain unsolved. Here, we report the impact of hypoxia-induced Jagged1 expression in cardiomyocytes (CMs) for driving the differentiation of cardiac stem cells (CSCs). Forced hypoxia-inducible factor 1α (HIF-1α) expression and physical hypoxia (5% O2) treatment could induce Jagged1 expression in neonatal rat CMs. Pharmacological inhibition of HIF-1α by YC-1 attenuated hypoxia-promoted Jagged1 expression in CMs. An ERK inhibitor (PD98059), but not inhibitors of JNK (SP600125), Notch (DAPT), NF-κB (PTDC), JAK (AG490), or STAT3 (Stattic) suppressed hypoxia-induced Jagged1 protein expression in CMs. c-Kit+ CSCs isolated from neonatal rat hearts using a magnetic-activated cell sorting method expressed GATA4, SM22α or vWF, but not Nkx2.5 and cTnI. Moreover, 87.3% of freshly isolated CSCs displayed Notch1 receptor expression. Direct co-culture of CMs with BrdU-labeled CSCs enhanced CSCs differentiation, as evidenced by an increased number of BrdU+/Nkx2.5+ cells, while intermittent hypoxia for 21 days promoted co-culture-triggered differentiation of CSCs into CM-like cells. Notably, YC-1 and DAPT attenuated hypoxia-induced differentiation. Our results suggest that hypoxia induces Jagged1 expression in CMs primarily through ERK signaling, and facilitates early cardiac lineage differentiation of CSCs in CM/CSC co-cultures via HIF-1α/Jagged1/Notch signaling.

Abstract
The adult mammalian heart doesn't regenerate after cardiomyocyte injury, which was mainly caused by the severe and persistent effects of cardiomyopathy. Recently, some studies reported that the mammalian heart can regenerate under low oxygen environment. However, the mechanism that the mammalian heart can regenerate remains unknown. Here, we used cardiac stem cells (CSCs) to be planted in serum-free medium under hypoxia environment to understand the mechanism of HIF1α/NDUFA4L2 in the regulation of hypoxia-alleviated apoptosis. Our results revealed that hypoxia can alleviated CSCs apoptosis. Hypoxia inhibited the level of cleaved-caspase3 and stimulated the expression of stabilized HIF-1α. DMOG promotes the survival of CSCs and the protein expression of NDUFA4L2. 2-ME repressed the survival of CSCs and the protein expression of NDUFA4L2. CHIP assay showed that HIF-1α regulated the survival of CSCs by augmenting the combination of HIF-1α and NDUFA4L2's HRE. Knockdown of NDUFA4L2 reversed the role of hypoxia in the survival of CSCs. Taken together, hypoxia promotes the viability of CSCs in serum-free medium by HIF-1α/NDUFA4L2 signaling pathway.

Abstract
It is well-known that cardiovascular diseases are the leading cause of death worldwide, and represent an important economic burden to health systems. In an attempt to solve this problem, stem cell therapy has emerged as a therapeutic option. Within the last 20 years, a great variety of stem cells have been used in different myocardial infarction models. Up until now, the use of cardiac stem cells (CSCs) has seemed to be the best option, but the inaccessibility and scarcity of these cells make their use unreliable. Additionally, there is a high risk as they have to be obtained directly from the heart of the patient. Unlike CSCs, adult stem cells originating from bone marrow or adipose tissue, among others, appear to be an attractive option due to their easier accessibility and abundance, but particularly due to the probable existence of cardiac progenitors among their different sub-populations. In this review an analysis is made of the surface markers present in CSCs compared with other adult stem cells. This suggested the pre-existence of cells sharing specific surface markers with CSCs, a predictable immunophenotype present in some cells, although in low proportions, and with a potential of cardiac differentiation that could be similar to CSCs, thus increasing their therapeutic value. This study highlights new perspectives regarding MSCs that would enable some of these sub-populations to be differentiated at cardiac tissue level.

Abstract
OBJECTIVES Heart failure is a significant cause of mortality worldwide, and most current therapies treat only its symptoms. The results of cardiac stem cell research suggest a promising treatment option for heart failure, but there is currently an unmet demand for better research models. We have therefore, for the first time, isolated, expanded and differentiated progenitor cells obtained from juvenile pig hearts to use as a platform for cardiac stem cell research. DESIGN Progenitor cells were isolated from the left ventricles of porcine hearts using collagenase enzymatic digestion and Percoll®-gradient centrifugation. Cells were proliferated in Matrigel®-coated wells. Cell differentiation was initiated by applying 5-azacytidine and subsequently controlled by modifying the serum concentration. Western blotting and qPCR were used to determine protein and gene expression, respectively. RESULTS Cardiac-specific genes, from the following proteins: troponin I-3, and myosin-heavy-chain 7 were stably expressed during proliferation and differentiation. Connexin-43 was upregulated and Actinin alfa 2 was downregulated during differentiation. The immature-cardiomyocyte marker GATA binding protein 4 was stably expressed but with a decrease in expression at day 4 of differentiation. Smooth muscle actin decreased in expression and Von Willebrand factor were stably expressed during differentiation. Smooth muscle protein expression was documented but no expression of cardiac-specific proteins after differentiation was found. CONCLUSION The isolated progenitor cells had key cardiac-lineage gene expression characteristics but they did not express cardiac-specific proteins. Smooth muscle protein was expressed confirming commitment to the smooth muscle lineage.

Abstract
Cell sheets (CS) from c-kit+ cardiac stem cell (CSC) hold a potential for application in regenerative medicine. However, manufacture of CS may require thermoresponsive dishes, which increases cost and puts one in dependence on specific materials. Alternative approaches were established recently and we conducted a short study to compare approaches for detachment of CS from c-kit+ CSC. Our in-house developed method using chelation by Versene solution was compared to UpCell™ thermoresponsive plates in terms of CSC proliferation, viability, gap junction formation and engraftment in a model of myocardial infarction. Use of Versene solution instead of thermoresponsive dishes resulted in comparable CS thickness (approximately 100mcm), cell proliferation rate and no signs of apoptosis detected in both types of constructs. However, we observed a minor reduction of gap junction count in Versene-treated CS. At day 30 after delivery to infarcted myocardium both types of CS retained at the site of transplantation and contained comparable amounts of proliferating cells indicating engraftment. Thus, we may conclude that detachment of CS from c-kit+ CSC using Versene solution followed by mechanical treatment is an alternative to thermoresponsive plates allowing use of routinely available materials to generate constructs for cardiac repair.

Abstract
Congestive heart failure (CHF) secondary to chronic coronary artery disease is a major cause of morbidity and mortality world-wide. Its prevalence is increasing despite advances in medical and device therapies. Cell based therapies generating new cardiomyocytes and vessels have emerged as a promising treatment to reverse functional deterioration and prevent the progression to CHF. Functional efficacy of progenitor cells isolated from the bone marrow and the heart have been evaluated in preclinical large animal models. Furthermore, several clinical trials using autologous and allogeneic stem cells and progenitor cells have demonstrated their safety in humans yet their clinical relevance is inconclusive. This review will discuss the clinical therapeutic applications of three specific adult stem cells that have shown particularly promising regenerative effects in preclinical studies, bone marrow derived mesenchymal stem cell, heart derived cardiosphere-derived cell and cardiac stem cell. We will also discuss future therapeutic approaches.

Abstract
As the search for new cell types for cardiovascular regeneration continues, it has become increasingly important to optimize ex vivo cell processing. We aimed to develop an optimal processing strategy for human cardiac progenitor cells. We hypothesized that enhancing the stemness potential and promoting the secretory activity for paracrine effects are mutually exclusive routes. Therefore, we investigated the two divergent cell processing methods to enhance cellular potency and humoral activity, respectively. We obtained human right ventricular tissues and sequentially generated primary cardiosphere (CS), primary CS-derived cells (PCDC) and secondary CSs. During secondary CS formation, inhibiting the ERK pathway, using selective RTK1 and TGF-β inhibitors, Oct4 increased 20 fold and VEGF was decreased. When the ERK pathway was stimulated by addition of EGF and TGF-β, VEGF expression was upregulated and Oct4 was downregulated, indicating that the ERK pathway serves a directional role for cellular potency versus paracrine capacity. Transplantation of PCDCs or secondary CSs into the infarcted heart of immunocompromised mouse showed significant angiogenic effects compared with PBS injection. Interestingly, combined transplantation of the two differently-processed, dual-purpose secondary CSs resulted in an additional increase in neovascularization. Human VEGF was primarily produced from secondary CSs under ERK stimulating conditions. Cardiomyocyte-like cells were produced from secondary CSs under ERK inhibitory conditions. These findings indicate that combined transplantation of specifically-processed human secondary CSs enhances infarct repair through the complementary enhancement of cardiopoietic regenerative and paracrine protective effect. Furthermore, these results underscore the fact that optimal cell processing methods have the potential to maximize the therapeutic benefits.
