Abstract
After more than 20 years following the introduction of regenerative medicine to address the problem of cardiac diseases, still questions arise as to the best cell types and materials to use to obtain effective clinical translation. Now that it is definitively clear that the heart does not have a consistent reservoir of stem cells that could give rise to new myocytes, and that there are cells that could contribute, at most, with their pro-angiogenic or immunomodulatory potential, there is fierce debate on what will emerge as the winning strategy. In this regard, new developments in somatic cells' reprogramming, material science and cell biophysics may be of help, not only for protecting the heart from the deleterious consequences of aging, ischemia and metabolic disorders, but also to boost an endogenous regeneration potential that seems to be lost in the adulthood of the human heart.

Safety, feasibility and effectiveness of first in-human administration of muscle-derived stem/progenitor cells modified with connexin-43 gene for treatment of advanced chronic heart failure. Eur J Heart Fail 2017; 19:148-157.

Abstract
AIMS To assess the safety and efficacy of transendocardial delivery of muscle-derived stem/progenitor cells with connexin-43 overexpression (Cx-43-MDS/PC) in advanced heart failure (HF). METHODS AND RESULTS Thirteen subjects with advanced HF, New York Heart Association (NYHA) class II-III were enrolled and treated with targeted injection of Cx-43-MDS/PCs and then monitored for at least 6 months. Overexpression of Cx43 (Cx43+) was significantly higher in all but one subject (Cx43-). Injection of MDS/PCs was associated with significant improvement of exercise capacity: NYHA (3 ± 0 vs. 1.8 ± 0.7, P = 0.003), exercise duration (388.69 ± 141.83 s vs. 462.08 ± 176.69 s, P = 0.025), peak oxygen consumption (14.38 ± 3.97 vs. 15.83 ± 3.74 ml/kg.min, P = 0.022) and oxygen pulse (10.58 ± 2.89 vs. 18.88 ± 22.63 mLO2 /heart rate, P = 0.012). Levels of BNP, left ventricular (LV) ejection fraction and LV end-diastolic volumes tended to improve. There was a significant improvement of the mean unipolar voltage amplitudes measured for the injected segments and the entire left ventricle (9.62 ± 2.64 vs. 11.62 ± 3.50 mV, P = 0.014 and 8.83 ± 2.80 vs. 10.22 ± 3.41 mV, P = 0.041, respectively). No deaths were documented, Cx43+ (n = 12) subjects presented no significant ventricular arrhythmia; one Cx43- subject suffered from ventricular tachycardia (successfully treated with amiodarone). CONCLUSIONS Injection of Cx-43-MDS/PCs in patients with severe HF led to significant improvement in exercise capacity and myocardial viability of the injected segments while inducing no significant ventricular arrhythmia. This may arise from improved electrical coupling of the injected cells and injured myocardium and thus better in-situ mechanical cooperation of both cell types. Therefore, further clinical studies with Cx43+ MDS/PCs are warranted.

Abstract
Skeletal myoblasts function as precursors to adult skeletal myocytes. More so than other muscle progenitors, their capacity for de novo self-renewal and their positive functional effects in the cardiac environment have been demonstrated, even though they do not attain a cardiomyocyte phenotype. Autologous skeletal myoblasts are easily procured by established methods and can be administered into diseased myocardium safely and without technical difficulty, features that at this time set them apart from any other myogenic cell. Clinical studies in patients with chronic myocardial disease have consistently reported modest improvements in ventricular function and clinical status. Data from the Myogenesis Heart efficiency and Regeneration Trial (MYOHEART) trial are currently being evaluated. Larger, randomized, placebo-controlled studies in patients with congestive heart failure due to postinfarction systolic left ventricular dysfunction are under way, such as Myoblast Autologous Grafting in Ischemic Cardiomayopathy (MAGIC) and Multicenter Study of the Safety and Cardiovascular Effects Of Myoblasts in Congestive Heart Failure (MARVEL). The future role of skeletal myoblasts in the clinical setting will be determined by the results of randomized trials as well as by the investigation of subsequent generations of myoblasts, engineered for enhanced efficacy.

Abstract
Despite significant therapeutic advances, the prognosis of patients with heart failure (HF) remains poor, and current therapeutic approaches are palliative in the sense that they do not address the underlying problem of the loss of cardiac tissue. Stem cell-based therapies have the potential to fundamentally transform the treatment of HF by achieving what would have been unthinkable only a few years ago-myocardial regeneration. For the first time since cardiac transplantation, a therapy is being developed to eliminate the underlying cause of HF, not just to achieve damage control. Since the initial report of cell therapy (skeletal myoblasts) in HF in 1998, research has proceeded at lightning speed, and numerous preclinical and clinical studies have been performed that support the ability of various stem cell populations to improve cardiac function and reduce infarct size in both ischemic and nonischemic cardiomyopathy. Nevertheless, we are still at the dawn of this therapeutic revolution. Many important issues (eg, mechanism(s) of action of stem cells, long-term engraftment, optimal cell type(s), and dose, route, and frequency of cell administration) remain to be resolved, and no cell therapy has been conclusively shown to be effective. The purpose of this article is to critically review the large body of work performed with respect to the use of stem/progenitor cells in HF, both at the experimental and clinical levels, and to discuss current controversies, unresolved issues, challenges, and future directions. The review focuses specifically on chronic HF; other settings (eg, acute myocardial infarction, refractory angina) are not discussed.

Abstract
Angiogenic gene therapy and stem cell administration represent two "biologic" interventions for the treatment of cardiac disease that were first introduced more than 15 years ago but still have not achieved approval for clinical use for the treatment of myocardial ischemia and heart failure. Challenges that have been encountered in the clinical testing of these new treatment strategies have included a lack of placebo controls in phase I surgical trials and the incorporation of potentially ineffectual agent delivery via intracoronary routes. Although enthusiasm for these approaches may therefore have ebbed, new refinements in these technologies and insights into their appropriate clinical testing suggest that a resurgence of interest in these "biointerventions" may be expected in the near future.

Abstract
Stem cells provide an alternative curative intervention for the infarcted heart by compensating for the cardiomyocyte loss subsequent to myocardial injury. The presence of resident stem and progenitor cell populations in the heart, and nuclear reprogramming of somatic cells with genetic induction of pluripotency markers are the emerging new developments in stem cell-based regenerative medicine. However, until safety and feasibility of these cells are established by extensive experimentation in in vitro and in vivo experimental models, skeletal muscle-derived myoblasts, and bone marrow cells remain the most well-studied donor cell types for myocardial regeneration and repair. This article provides a critical review of skeletal myoblasts as donor cells for transplantation in the light of published experimental and clinical data, and indepth discussion of the advantages and disadvantages of skeletal myoblast-based therapeutic intervention for augmentation of myocardial function in the infarcted heart. Furthermore, strategies to overcome the problems of arrhythmogenicity and failure of the transplanted skeletal myoblasts to integrate with the host cardiomyocytes are discussed.

Abstract
Satellite cells are committed precursor cells residing in the skeletal muscle. These cells provide an almost unlimited regeneration potential to the muscle, contrary to the heart, which, although proved to contain cardiac stem cells, possesses a very limited ability for self-renewal. The idea that myoblasts (satellite cell progenies) may repopulate postinfarction scar occurred around the mid-1990s. Encouraging results of preclinical studies triggered extensive research, which led to the onset of clinical trials. These trials have shown that autologous skeletal myoblast transplantation to cure heart failure is feasible and relatively safe (observed incidences of arrhythmia). Because most of the initial studies on myoblast application into postischemic heart have been carried out as an adjunct to routine surgical procedures, the true clinical outcome of such therapy in regard to cell implantation is blurred and requires to be elucidated. The mechanism by which implantation of skeletal myoblast may improve heart function is not clear, especially in the light of inability of these cells to couple electromechanically with a host myocardium. Successful myoblast therapy depends on a number of factors, including: delivery to the target tissue, long-term survival, efficacious engraftment, differentiation into cardiomyocytes, and integration into the new, unique microenvironment. All these steps constitute a potential goal for cell manipulation aiming to improve the overall outcome of such therapy. Precise understanding of the mechanism by which cells improve cardiac function is essential in giving the sensible direction of further research.

Abstract
Over the past decade, cell therapy has emerged as a potential new treatment of a variety of cardiac diseases, including acute myocardial infarction, refractory angina, and chronic heart failure. A myriad of cell types have been tested experimentally, each of them being usually credited by its advocates of a high "regeneration" potential. This has led to a flurry of clinical trials entailing the use of skeletal myoblasts or bone marrow-derived cells either unfractionated or enriched in progenitor subpopulations. As often in medicine, the hype generated by the early uncontrolled and small-sized studies has been dampened by the marginally successful outcomes of the subsequent, more rigorously conducted randomized trials. Although they may have failed to achieve their primary end points, these trials have been positive in the sense that they have allowed to identify some key issues and it is reasonable to speculate that if these issues can now be addressed by appropriately focused benchwork, the outcomes of the second generation of cell-transplantation studies would likely be upgraded. It, thus, appears that not "one cell fits all" but that the selection of the cell type should be tailored to the primary clinical indication. On the one hand, it does not make sense to develop an "ideal" cell in a culture dish, if we remain unable to deliver it appropriately and to keep it alive, at least for a while, which requires to improve on the delivery techniques and to provide cells along with the vascular and extracellular matrix type of support necessary for their survival and patterning. On the other hand, the persisting mechanistic uncertainties about cell therapy should not preclude continuing clinical trials, which often provide the unique opportunity of identifying issues missed by our suboptimal preclinical models. Finally, regardless of whether cells are expected to act paracrinally or by physically replacing lost cardiomyocytes and, thus, effecting a true myocardial regeneration, safety remains a primary concern. It is, thus, important that clinical development programs be shaped in a way that allows the final cell-therapy product to be manufactured from fully traceable materials, phenotypically well characterized, consistent, scalable, sterile, and genetically stable as these characteristics are those that will be required by the ultimate gatekeeper, i.e., the regulator, and are thus unbypassable prerequisites for an effective and streamlined leap from bench to bedside.

Abstract
Although most cardiac cell therapy trials have focused on patients with acute myocardial infarction, attempts at "regenerating" chronically failing hearts have also been performed. These studies have entailed use of skeletal myoblasts and bone marrow-derived cells. In the case of skeletal myoblasts, the randomized placebo-controlled myoblast autologous grafting in ischemic cardiomyopathy (MAGIC) trial has failed to show that myoblast injections increased ejection fraction beyond that seen in controls but the finding that the highest dose of myoblasts resulted in a significant antiremodeling effect compared with the placebo group provides an encouraging signal. In the case of bone marrow cells, surgical injections of the mononuclear fraction combined with coronary artery bypass surgery have not shown a substantial benefit but positive results have been reported with intraoperative epicardial injections of CD133(+) progenitors. There are three possible reasons for these mixed results. The first is the marked heterogeneity of cell functionality (particularly in the case of bone marrow), which would expectedly translate into variable clinical outcomes. The second reason is the low rate of sustained engraftment. The third possible explanation is a mismatch between the choice of end points and the presumed mechanism of action of the cells. The initial assumption that adult stem cells could effect myocardial tissue regeneration has led to usual focus on ejection fraction as the major surrogate endpoint. It is now increasingly recognized that adult stem cells, in contrast to their embryonic counterparts, have little if any regenerative capacity and that their presumed beneficial effects more likely involve paracrine signaling, in which case infarct size, perfusion, or left ventricular volumes might be more appropriate markers. Altogether, these observations provide a framework for future research, the results of which will then have to be integrated in the protocol design of second-generation clinical trials.

Abstract
Background—
Phase I clinical studies have demonstrated the feasibility of implanting autologous skeletal myoblasts in postinfarction scars. However, they have failed to determine whether this procedure was functionally effective and arrhythmogenic.
Methods and Results—
This multicenter, randomized, placebo-controlled, double-blind study included patients with left ventricular (LV) dysfunction (ejection fraction ≤35%), myocardial infarction, and indication for coronary surgery. Each patient received either cells grown from a skeletal muscle biopsy or a placebo solution injected in and around the scar. All patients received an implantable cardioverter-defibrillator. The primary efficacy end points were the 6-month changes in global and regional LV function assessed by echocardiography. The safety end points comprised a composite index of major cardiac adverse events and ventricular arrhythmias. Ninety-seven patients received myoblasts (400 or 800 million; n=33 and n=34, respectively) or the placebo (n=30). Myoblast transfer did not improve regional or global LV function beyond that seen in control patients. The absolute change in ejection fraction (median [interquartile range]) between 6 months and baseline was 4.4% (0.2; 7.3), 3.4% (−0.3; 12.4), and 5.2% (−4.4; 11.0) in the placebo, low-dose, and high-dose groups, respectively (
P
=0.95). However, the high-dose cell group demonstrated a significant decrease in LV volumes compared with the placebo group. Despite a higher number of arrhythmic events in the myoblast-treated patients, the 6-month rates of major cardiac adverse events and of ventricular arrhythmias did not differ significantly between the pooled treatment and placebo groups.
Conclusions—
Myoblast injections combined with coronary surgery in patients with depressed LV function failed to improve echocardiographic heart function. The increased number of early postoperative arrhythmic events after myoblast transplantation, as well as the capability of high-dose injections to revert LV remodeling, warrants further investigation.

Ischemic central necrosis in pockets of transplanted myoblasts in nonhuman primates: implications for cell-transplantation strategies. Transplantation 2007; 84:1307-15.

Abstract
BACKGROUND Several cell-transplantation strategies implicate the injection of cells into tissues. Avascular accumulations of implanted cells are then formed. Because the diffusion of oxygen and nutrients from the surrounding tissue throughout the implanted cell accumulations may be limited, central ischemic necrosis could develop. We analyzed this possibility after myoblast transplantation in nonhuman primates. METHODS Macaca monkeys were injected intramuscularly with different amounts of myoblasts per single site. These sites were sampled 1 hr later and at posttransplantation days 1, 3, 5, and 7 and analyzed by histological techniques. RESULTS One day posttransplantation, the largest pockets of implanted cells showed cores of massive necrosis. The width of the peripheral layer of living cells was approximately 100-200 microm. We thus analyzed the relationship between the amount of myoblasts injected per site and the volume of ischemic necrosis. Delivering 0.1 x 10(6) and 0.3 x 10(6) myoblasts did not produce ischemic necrosis; pockets of 1 x 10(6), 3 x 10(6), 10 x 10(6), and 20 x 10(6) myoblasts exhibited, respectively, a mean of 2%, 9%, 41%, and 59% of central necrosis. Intense macrophage infiltration took place in the muscle, invading the accumulations of necrotic cells and eliminating them by posttransplantation days 5 to 7. CONCLUSIONS The desire to create more neoformed tissue by delivering more cells per injection site is confronted with the fact that the acute survival of the implanted cells is restricted to the peripheral layer that can profit of the diffusion of oxygen and nutriments from the surrounding recipient's tissue.

Abstract
Cellular transplantation has been employed for several years to deliver donor cardiomyocytes to normal and injured hearts. Recent reports of a variety of stem cells with apparent cardiomyogenic potential have raised the possibility of cell transplantation-based therapeutic interventions for heart disease. Here we review the preclinical studies demonstrating that intracardiac transplantation of skeletal myoblasts, cardiomyocytes and cardiomyogenic stem cells is feasible. In addition, recent clinical studies of skeletal myoblast and adult stem cell transplantation for heart disease are discussed.

Abstract
Cell transplantation is emerging as a new treatment designed to improve the poor outcome of patients with cardiac failure. Its rationale is that implantation of contractile cells into postinfarction scars could functionally rejuvenate these areas. Primarily for practical reasons, autologous skeletal myoblasts have been the first to be considered for a clinical use. A large number of experimental studies have consistently documented a robust engraftment of myoblasts, their in-scar differentiation into myotubes, and an associated improvement in left ventricular function. The early results of phase I clinical trials have then established both the feasibility and safety of this procedure with the caveat of arrhythmic events. Efficacy data are equally encouraging but definitely need to be validated by large prospective placebo-controlled, double-blind randomized trials such as the Myoblast Autologous Grafting in Ischemic Cardiomyopathy (MAGIC) study, the results of which are now pending. In addition to assessing the effect of myoblast transplantation on regional and global heart function, these results will also provide comprehensive safety data and thus allow a more objective assessment of the risk-benefit ratio. However, it is already apparent that the outcome of myoblast transfer could most likely be improved by optimizing the purity of the cell yield (by selecting muscle-derived progenitors less lineage-committed than the myoblasts), the mode of delivery (by increasing the accuracy of cell injections while decreasing their invasiveness), and the survival of the engrafted cells (by concomitant graft vascularization and incorporation of cells in three-dimensional matrices). Most, if not all, of these changes will have to be incorporated before skeletal myoblasts can acquire the status of therapeutic agents. Furthermore, there is increasing evidence that myoblasts may act by attenuating left ventricular remodeling or paracrinally affecting the surrounding myocardium but not by generating new cardiomyocytes because of their strict commitment to a myogenic lineage. Thus, improvement of function is not tantamount of myocardial regeneration, and if such a regeneration remains the primary objective, it is worth considering alternate cell types able to generate new cardiac cells that will be electromechanically coupled with the host cardiomyocytes. In the setting of this second generation of cells, human cardiac-specified embryonic stem cells may hold the greatest promise.

Abstract
Cardiac cell therapy has been initially designed to regenerate the infarcted myocardium through its repopulation by new cells able to restore function of scar areas. Six years after the first human application of this novel approach, it is timely appropriate to review the results of the first randomised trials in the three major indications, i.e., acute myocardial infarction, heart failure, and refractory angina. It should be recognized that the results are mixed, with benefits ranging from absent to transient and, at most, marginal. However, lessons drawn from this first wave of clinical series and the experimental data that have been concomitantly collected are multiple and highly informative. They indicate that adult stem cells, whether muscular or bone marrow-derived, fail to generate new cardiomyocytes. They suggest that the potential benefits of cardiac cell therapy are thus mediated by alternate mechanisms such as limitation of left ventricular remodelling or paracrine activation of signalling pathways involved in angiogenesis. They highlight the fact that the therapeutic benefits of grafted cells will not be fully exploited until issues of cell transfer and postengraftment survival have not been adequately addressed. These observations thus allow us to better fine-tune upcoming research, which should specifically concentrate on the development of cells featuring a true regeneration potential. In this setting, the greatest promises are currently held by embryonic stem cells.
