Cardiovascular diseases resulting from ischemic heart diseases remain to be the main causes of heart failure and death despite significant advances in medical treatment. The development of new therapies for heart failure is thus required to improve the outcome in these patients, and this has led to the development of cell-based therapies. Animal studies showed interesting results using various cell types. Some stem cell based therapies have been tested in clinical trials. Although the results were encouraging, challenges remain...

Mesenchymal stem cells (MSCs) are multipotent stem cells that reside in various organs. They have the capacity to differentiate into various cell types, including cardiomyocytes, vascular endothelial cells, and vascular smooth muscle cells. Among the various MSCs, bone marrow-derived MSCs (BMMSCs) have been widely used for treating acute myocardial infarction (AMI) and ischemic heart failure (IHF) in preclinical and clinical studies. Although the beneficial effects of BMMSCs in treating AMI and IHF were originally attributed to their capacity to differentiate into cardiac cell types, recent evidence suggests that the differentiation capacity of BMMSCs appears to be minimal and that BMMSCs exert cardioprotective effects by secreting paracrine factors...

Peripartum cardiomyopathy (PPCM) refers to irreversible cardiomyocyte damage that occurs during the last month of pregnancy, or within 5 months after giving birth. It is characterized by systolic heart failure. This life-threatening condition is relatively uncommon, but the incidence has been climbing up. Because of its high mortality, it is crucial for physicians to have high suspicious for the disease. Studies have been done to search into specific lab test and treatment for PPCM. Therapies like anti-viral, anti-inflammatory and immunosuppression regimen have been explored...

Diabetic subjects are at risk of developing cardiovascular disease, which accounts for 60-80% of diabetes-related mortality. Atherosclerosis is still considered as a leading cause of heart failure in diabetic patients, but it could also be an intrinsic and long-term effect of contractile cardiac cells malfunction, known as diabetic cardiomyopathy (DCM). Pathologically, this cardiac dysfunction is manifested by inflammation, apoptosis, fibrosis, hypertrophy and altered cardiomyocytes metabolism. However, the underlying molecular mechanisms of DCM pathophysiology are not clearly understood...

Myocardial hypertrophy is a common cardiac condition in response to hemodynamic and neurohormonal alterations. Pathological hypertrophic growth in hearts caused the decline of cardiac functions, and finally developed into congestive heart failure. The exosomes are small membrane vesicles which are secreted by various cells and play important roles in cellular communication, migration, proliferation and differentiation. Recent studies uncovered that the exosomes from cardiac fibroblasts and other tissues participates in the development of myocardial hypertrophy...

Cardiovascular diseases (CVDs) have a high prevalence and annually increasing incidence with high mortality and morbidity. Identification of biomarkers with high sensitivity and specificity for assessing the prognosis of CVDs is necessary for optimizing personalized treatment and reducing mortality. Exosomes have been proved to be accessible in nearly all body fluids and they can reflect disease stage or progression. Here we summarized exosomes-based biomarkers for the prognosis of coronary artery diseases, heart failure, stroke, hypertension, cardiac arrhythmia, cardiomyopathy, valvular heart diseases and pulmonary arterial hypertension...

Myxomatous mitral valve disease (MMVD) is functionally and histologically identical to mitral valve prolapse (MVP) in humans. Currently, there are no medical treatments that can delay the progression of this valvular disease or associated cardiac remodelling. Therefore, there is a need to understand the molecular pathology associated with MMVD and MVP better, and thus identify potential therapeutic targets. Circulating exosomes contain small RNA, including miRNA, which reflect cell physiology and pathology...

BACKGROUND: Exosomes are cell-derived circulating vesicles that play an important role in cell-cell communication. Exosomes are actively assembled and carry messenger RNAs, microRNAs and proteins. The "gold standard" for cardiac allograft surveillance is endomyocardial biopsy (EMB), an invasive technique with a distinct complication profile. The development of novel, non-invasive methods for the early diagnosis of allograft rejection is warranted. We hypothesized that the exosomal proteome is altered in acute rejection, allowing for a distinction between non-rejection and rejection episodes...

Diabetic cardiomyopathy is characterised in its early stages by diastolic relaxation abnormalities and later by clinical heart failure in the absence of dyslipidaemia, hypertension and coronary artery disease. Insulin resistance, hyperinsulinaemia and hyperglycaemia are each independent risk factors for the development of diabetic cardiomyopathy. The pathophysiological factors in diabetes that drive the development of cardiomyopathy include systemic metabolic disorders, inappropriate activation of the renin-angiotensin-aldosterone system, subcellular component abnormalities, oxidative stress, inflammation and dysfunctional immune modulation...

Exosomes are small vesicles that contain proteins, DNA and RNA, and play an important role in inflammation; however, the underlying mechanism remains unclear. In the present study, we found increased plasma-derived exosomes in chronic heart failure patients compared with healthy controls. Further, our data demonstrated that plasma-derived exosomes carried mtDNA, and triggered an inflammatory response via the TLR9-NF-κB pathway, as well, the inflammatory effect was closely related to exosomal mtDNA copy number...

The finances of patients and countries are increasingly overwhelmed with the plague of cardiovascular diseases as a result of having to chronically manage the associated complications of ischemia such as heart failures, neurological deficits, chronic limb ulcers, gangrenes, and amputations. Hence, scientific research has sought for alternate therapies since pharmacological and surgical treatments have fallen below expectations in providing the desired quality of life. The advent of stem cells research has raised expectations with respect to vascular regeneration and tissue remodeling, hence assuring the patients of the possibility of an improved quality of life...

Stimulation of the renin-angiotensin-aldosterone system (RAAS) and β-adrenergic receptors plays an important role in adult heart failure (HF). Despite the demonstrated benefits of RAAS inhibition and β-adrenergic receptor blockade in adult HF patients, no substantial improvement in survival rate has been observed in children with HF. This suggests that the underlying disease mechanism is uniquely regulated in pediatric HF. Here, we show that treatment of human-induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs) and neonatal rat ventricular myocytes (NRVMs) with serum from pediatric dilated cardiomyopathy (DCM) patients induces pathological changes in gene expression, which occur independently of the RAAS and adrenergic systems, suggesting that serum circulating factors play an important role in cardiac remodeling...

Cardiovascular disease is the leading cause of death worldwide. The heart is susceptible to pathologies that impact the myocardium directly, such myocardial infarction and consequent heart failure, as well as conditions with indirect cardiac effects, such cancer treatment-related cardiotoxicity. As the contractile cells of the heart, cardiomyocytes are essential for normal cardiac function. Various stress stimuli may result in transient damage or cell death in cardiomyocytes through apoptosis, necrosis or maladaptive autophagy...

For almost two decades, cell-based therapies have been tested in modern regenerative medicine to either replace or regenerate human cells, tissues, or organs and restore normal function. Secreted paracrine factors are increasingly accepted to exert beneficial biological effects that promote tissue regeneration. These factors are called the cell secretome and include a variety of proteins, lipids, microRNAs, and extracellular vesicles, such as exosomes and microparticles. The stem cell secretome has most commonly been investigated in pre-clinical settings...

Mesenchymal stem cells (MSCs) have been used to treat patients suffering from acute myocardial infarction (AMI) and subsequent heart failure. Although it was originally assumed that MSCs differentiated into heart cells such as cardiomyocytes, recent evidence suggests that the differentiation capacity of MSCs is minimal and that injected MSCs restore cardiac function via the secretion of paracrine factors. MSCs secrete paracrine factors in not only naked forms but also membrane vesicles including exosomes containing bioactive substances such as proteins, messenger RNAs, and microRNAs...

Every year 13.3 million people suffer acute kidney injury (AKI), which is associated with a high risk of death or development of long-term chronic kidney disease (CKD) in a substantial percentage of patients besides other organ dysfunctions. To date, the mortality rate per year for AKI exceeds 50 % at least in patients requiring early renal replacement therapy and is higher than the mortality for breast and prostate cancer, heart failure and diabetes combined.Until now, no effective treatments able to accelerate renal recovery and improve survival post AKI have been developed...

BACKGROUND: Cell-based therapies are being explored as a therapeutic option for patients with chronic heart failure following myocardial infarction. Extracellular vesicles (EV), including exosomes and microparticles, secreted by transplanted cells may orchestrate their paracrine therapeutic effects. We assessed whether post-infarction administration of EV released by human embryonic stem cell-derived cardiovascular progenitors (hESC-Pg) can provide equivalent benefits to administered hESC-Pg and whether hESC-Pg and EV treatments activate similar endogenous pathways...

Injured or ischemic cardiac tissue has limited intrinsic capacity for regeneration. While stem cell transplantation is a promising approach to stimulating cardiac repair, its success in humans has thus far been limited. Harnessing the therapeutic benefits of stem cells requires a better understanding of their mechanisms of action and methods to optimize their function. Cardiac stem cells (CSC) represent a particularly effective cellular source for cardiac repair, and pre-conditioning CSC with electrical stimulation (EleS) was demonstrated to further enhance their function, although the mechanisms are unknown...

Intercellular communication mediated by extracellular vesicles is crucial for preserving vascular integrity and in the development of cardiovascular disease. Extracellular vesicles consist of apoptotic bodies, microvesicles, and exosomes that can be found in almost every fluid compartment of the body like blood, saliva, and urine. In the recent years, a lot of reports came up suggesting that major cardiovascular and metabolic pathologies like atherogenesis, heart failure, or diabetes are highly influenced by transfer of microRNAs via extracellular vesicles leading to altered protein expression and phenotypes of recipient cells...
