Cardiovascular Diseases (CVDs) continue to be a leading cause of global morbidity and mortality, prompting researchers to explore innovative therapeutic approaches. Among these, stem cell therapy has emerged as a promising avenue, holding the potential to regenerate damaged cardiac tissue and improve heart function. This article provides a comprehensive overview of stem cell therapy in cardiovascular diseases, including the types of stem cells used, mechanisms of action, current clinical applications, challenges, and future directions. Stem cells are undifferentiated cells with the unique ability to differentiate into various cell types and self-renew. In the context of cardiovascular therapy, two main types of stem cells are commonly investigated: Embryonic Stem Cells (ESCs) and adult or somatic stem cells. ESCs are derived from the inner cell mass of embryos, while adult stem cells can be found in various tissues, such as the bone marrow, adipose tissue, and the heart itself. Induced Pluripotent Stem Cells (iPSCs) represent another category, generated by reprogramming adult cells to exhibit embryonic stem cell-like properties. One of the key mechanisms of stem cell therapy in cardiovascular diseases involves the differentiation of stem cells into functional cardiomyocytes. These newly formed heart cells integrate into damaged tissue, contributing to the regeneration of healthy myocardium. Stem cells also exert their therapeutic effects through paracrine signaling, where they release various growth factors, cytokines, and extracellular vesicles. These bioactive molecules promote tissue repair, angiogenesis, and anti-inflammatory responses, fostering a conducive environment for cardiac regeneration. Ischemic heart diseases, particularly Myocardial Infarction (MI), result from inadequate blood supply to the heart muscle. Stem cell therapy has shown promise in this context by enhancing myocardial regeneration, reducing scar formation, and improving overall cardiac function. Stem cells contribute to the formation of new blood vessels, a process known as angiogenesis. This is especially beneficial in ischemic conditions where improved blood supply can salvage damaged tissue and promote functional recovery. Over the past two decades, numerous clinical trials have been conducted to assess the safety and efficacy of stem cell therapy in cardiovascular diseases. Early trials focused on establishing the feasibility of using various stem cell types, such as bone marrow-derived cells, for myocardial repair. Recent advancements include trials exploring the use of iPSCs, cardiac progenitor cells, and Mesenchymal Stem Cells (MSCs). These trials aim to address specific challenges, such as improving engraftment, optimizing delivery methods, and enhancing the durability of therapeutic effects. One significant challenge in stem cell therapy for cardiovascular diseases is achieving robust engraftment and long-term survival of transplanted cells. Strategies to enhance cell survival and retention within the heart are actively being investigated. The immune response poses another challenge, particularly in allogeneic stem cell transplantation. Strategies to mitigate immunogenicity, such as using autologous cells or immunomodulatory approaches, are crucial for the success of stem cell therapies. The standardization of stem cell isolation, expansion, and delivery protocols is essential for ensuring reproducibility and comparability across different studies. This standardization is crucial for regulatory approval and widespread clinical implementation. Advancements in genome editing technologies, such as CRISPR-Cas9, offer the potential to enhance the therapeutic properties of stem cells. Precision editing can be employed to improve their engraftment, survival, and secretion of beneficial paracrine factors.
