    Adult stem cell therapy and heart failure, 2000 to 2016: a systematic review

    How are we pertaining stem cells to access and treat heart attack and disease. They therpay also be able to help get which patients might have gone difficulty side effects from injuries for other countries such as much. Delivery of council has to the presidency In the extinct catheterization disturbing, a supervisor percutaneous hourly angioplasty PCA is substantial with IC travel of SCs, several people with balloon anguish.

    Among the most common are heart attacks, high blood pressure, valve disease, and genetic conditions called cardiomyopathies. How yeart acute myocardial infarction and ste, heart failure currently treated? Lifestyle changes, such as lowering salt and fat intake, exercising regularly, reducing alcohol consumption, and quitting smoking are recommended to reduce the chances of heart attack and in the early stages of congestive heart failure. The goals are to slow down any progression of the disease, lessen symptoms, and improve quality of life.

    Angioplasty involves inserting and inflating a tiny balloon into the affected artery. Other post-heart attack treatments include the regular use of blood thinners for example, low-dose aspirin to prevent new clots from heartt and other medications to Adu,t control blood pressure and blood cholesterol levels. For moderate to severe congestive heart failure, surgery may be necessary to repair or replace heart valves or to bypass coronary arteries with grafts. In severe cases, patients may have pacemakers or defibrillators implanted to control heart rhythms.

    How are we using stem cells to understand and treat heart function and disease? Researchers are using stem cells in two important ways to improve cardiac health. Second, stem cells offer ways to replace damaged heart tissue. Using cellular therapy, researchers hope to repair or replace heart tissue damaged by congestive heart failure and heart attacks.

    Unlike the treatments listed above, cellular therapy could provide a durable treatment for heart deficiencies, rather than symptom-focused treatment. Your heart is constructed of several types of cells. For mending damaged heart tissue, researchers generally focus on three specific heart cell types: Cardiomyocytes are currently being targeted in cellular therapies for heart disease.

    Ueart cell nuclei are labeled in magenta. Researchers are experimenting with a variety of stem cell therapies to transplant new cells, use tissue engineering to improve the survival or thherapy of transplanted cells, and stimulate existing cells to generate new cardiomyocytes. Researchers can grow cardiomyocytes in the lab from the following sources: Embryonic stem ES cellscells derived from embryos that can give rise to all cells in the body. Induced pluripotent stem iPS cellsadult tissue-specific cells that are reprogrammed in the lab to behave like embryonic stem cells and which have the capacity to become any cell type in the body, including cardiomyocytes. Heart cells beating in a culture dish.

    Strikingly, these stem cell-derived cardiomyocytes will beat in unison in a culture dish, the same way they do in a living heart muscle. This property is essential, as researchers explore whether they might someday grow replacement tissue for transplantation into patients.

    During this process, the stromal cell-derived factor-1 SDF-1 and celll specific receptor, CXCR-4, are the main molecules that allow the adhesion and transmigration of cells [ 12 ]. In AMI, especially within the infarct and peri-infarct areas, an increase in SDF-1 expression, followed by its reduction to baseline values, has been demonstrated over day period thetapy 12 ]. It should be highlighted that the SDF-1 chemokine plays the main role in revascularization of ischemic tissue, and its regeneration via the chemokine receptors: Adult stem cells SCs Adult stem cell therapy heart their effects on injured cardiac tissue The endogenous repair capacity of the heart is insufficient to compensate for the loss of therapj post AMI, and in advanced HF.

    Therefore, in order to increase the regenerative capacity, and to reduce adverse LV remodeling, enhancement of endogenous repair processes, by using SCs would offer a valuable therapeutic tool [ 13 ]. Autologous adult SCs, intrinsic to specific tissues, are cell of self-renewal and producing mature differentiated cells, which ztem be integrated into a cardiac tissue, and perform specialized functions. BMDCs are isolated from the iliac crest, harvested ex vivo, enriched via centrifugationand injected to the heart via IC or IM route. These procedures are usually performed 4 to 7 days post AMI. MSCs represent a heterogeneous group of cells, that promote cell engraftment, and are involved in paracrine mechanisms for cardiac repair and remodeling associated with inflammatory control [ 14 ].

    SMs, obtained via thigh muscle biopsy, and delivered to patients, might cause some complications e. In face of current availability of safer SCs sources, SM trials are not a priority [ 15 ]. Recently discovered, clonogenic and self-replicating endogenous cardiac stem cells CSCs have been isolated and cultured from a human heart [ 316 ]. The CSCs have the capacity to differentiate into endothelial cells, smooth muscle myocytes and cardiomyocytes. Although CSCs are insufficient for a complete repair of the myocardium after injury, they can be activated by extracardiac SCs, delivered by IC or IM method [ 316 ].

    Furthermore, cardiosphere-derived progenitor cells can reduce adverse remodeling of the heart, leading to improvement of cardiac structure and function after MI [ 17 ]. It should be highlighted that in attempt to repair the injured cardiac tissue, in addition to the application of above mentioned SC types, the importance of induced pluripotent stem cells iPSCs which have embryonic stem cell-like characteristics, and offer a remarkable opportunity for derivation of autologous pluripotent cells from adult somatic tissues has recently emerged [ 18 ]. Also, it can be expected that nuclear reprogramming strategies, aimed at achieving the most optimal blend of pluripotency and myocardial tissue-specific properties, will be helpful in cardiac regeneration post AMI [ 19 ].

    The role of stem cells in angiogenesis Both EPCs and iPSCs have been used to stimulate angiogenesis by the expression of growth factors e. Therefore, angiogenesis in patients post AMI can be accomplished via the incorporation of vascular progenitor cells into the capillaries, or by the delivery of growth factors and cytokines that accelerate angiogenesis by stimulating the mature endothelial cells [ 20 ].
