Description

Cardiovascular disease is the world's biggest cause of death, making it a serious issue for global public health. Coronary Heart Disease (CHD) is the primary disease type generating the majority of fatalities among cardiovascular illnesses. Nowadays, medication, percutaneous coronary intervention (PCI), and surgery are the major methods used to treat CHD. These therapies may help with the symptoms of myocardial ischemia and heart failure to some extent. While the occluded artery is made clear again by the surgical procedures, the damage to the myocardial wall is permanent. The present surgical and pharmaceutical treatments can only provide palliative effects. The frequency of heart transplantation is being hampered by a lack of donor hearts and expensive costs. In 2001, researchers showed that autologous Bone Marrow Mesenchymal Stem Cells (BMSCs) mostly developed into cardiomyocytes after being implanted into a rat heart that had been injured. This significant finding inspired researchers to conduct several studies on the use of stem cells to treat Myocardial Infarction (MI). The conditions for cell culture and the method for generating differentiation in vitro have both seen significant advancements in the MSC research area. Using differentiated myocardial cells derived from stem cells to treat heart disorders offers hope. Adult Stem Cells (ASCs) and Embryonic Stem Cells (ESCs) are both types of stem cells that are capable of self-renewal and differentiation, respectively. Adult Stem Cells (ASCs) may be extracted from a number of adult tissues and developed into a wide range of cell types. Mesenchymal Stem Cells (MSCs), a kind of ASC, have been identified in almost all postnatal tissues or organs, including bone marrow, umbilical cord blood, and placenta. With several differentiation potentials, MSCs are a rare progenitor population. They have the capacity to develop into a variety of mesenchymal lineages, including those that produce cartilage, muscle, vascular endothelial cells, and epidermic cells. MSCs offer a high application potential in the individualized treatment of cardiovascular illnesses due to the benefit of autologous transplantation, which eliminates the immunological rejection and ethical problems. Biochemical drug induction in vitro, such as 5-aza, BMP-2, AngII, DMSO, and other herbs, are techniques to stimulate BMSC differentiation into cardiomyocyte-like cells. It is well recognized that chemical inducers may be harmful. Chemical inducers can cause cell death even at the optimum doses and during the ideal inducing period. Chemical inducers are not suitable for clinical translation because of their toxicity and unwanted effects. Additionally, the differentiation of BMSCs may be impacted by the cardiac microenvironment. As a result, it makes sense to develop culture conditions that more nearly resemble the heart environment, such as cardiomyocyte lysate, a medium for myocardial cell growth. Methods of differentiation that take into account the cardiac microenvironment will thus be more promising. According to a study, Clinical Laboratory Management (CLM) has a better inducing rate for cardiac cells than culture medium. According to the research, cardiomyocytes may emit certain soluble chemicals that help to induce BMSC development. Yet, unless the myocardial cells are ruptured, these compounds cannot be released. By directly coculturing with cardiomyocytes, MSCs interact with them in a paracrine and autocrine manner, resulting in physical stimulations including electrical activity and mechanical traction. Hence, CLM and direct coculturing with cardiac cells may be more practical among the several induction techniques. It is anticipated that using CLM and coculturing would help MSCs differentiate into cardiomyocytes even more. Mesenchymal stem cells from human bone marrow offer a wide range of potential applications since they may be acquired autologously and immunological rejection is not an issue. Moreover, it is simple to cultivate in vitro and has a variety of methods for inducing myocardial cell differentiation. Yet, there are still a number of issues that require attention. It is currently unclear what exact routes and control mechanisms cause hMSCs to differentiate into cells that resemble cardiomyocytes. To identify the ideal infusion dosage and time with various induction techniques, more research is required. It requires to increase the induction circumstances and further boost differentiation effectiveness to fulfil the clinical utilization.

Conclusion

The clinical translation of stem-cell-based therapy is a more difficult procedure, and many preclinical trials must be conducted to properly study and assess the efficacy of the therapy on a larger sample size. Consequently, the examination of the best/safest cell type and improvement following clinical therapy for MI are essential in stem cell research. More thought, a well-thought-out design, and careful experimentation are required for persuasive study. The application of BMSC transplantation to treat MI is expected to have a promising future with the advancement of technology and further study.
