心血管疾病, particularly heart failure, remain a leading cause of morbidity and mortality worldwide. Despite advancements in medical therapies and surgical interventions, the ability to restore cardiac function after injury or disease remains limited. 间充质干细胞 (间充质干细胞), with their unique regenerative and immunomodulatory properties, have emerged as a promising therapeutic approach for cardiac repair. This article provides an overview of the preclinical and clinical evidence supporting the use of MSCs in cardiac regeneration, highlighting the challenges and future directions of this field.

间充质干细胞: A Novel Therapeutic Approach for Cardiac Repair

MSCs are multipotent stromal cells with the capacity to differentiate into various cell lineages, 包括成骨细胞, 软骨细胞, 和脂肪细胞. They also possess paracrine effects, secreting a range of growth factors, 细胞因子, and extracellular vesicles that promote tissue repair and regeneration. 在心脏损伤的情况下, MSCs have demonstrated the ability to improve cardiac function, 减少梗塞面积, 并促进血管生成.

Preclinical Evidence for the Therapeutic Potential of MSCs in Cardiac Regeneration

Extensive preclinical studies have established the therapeutic potential of MSCs in cardiac regeneration. Animal models of myocardial infarction have shown that MSC transplantation can significantly improve cardiac function, 减少纤维化, 并增强血管生成. MSCs have also been shown to protect against ischemia-reperfusion injury, a major cause of myocardial damage during cardiac surgery or acute coronary syndromes.

临床试验: Assessing the Safety and Efficacy of MSC Therapy in Heart Failure

Clinical trials have been conducted to evaluate the safety and efficacy of MSC therapy in patients with heart failure. Early trials demonstrated the feasibility and safety of MSC transplantation, with no major adverse events reported. Subsequent trials have shown promising results, with improvements in cardiac function, 运动能力, 和生活质量. 然而, 更大, randomized controlled trials are needed to confirm the long-term clinical benefits of MSC therapy in heart failure.

Future Directions and Challenges in MSC-Based Cardiac Regeneration

尽管临床前和临床数据有希望, several challenges remain in the field of MSC-based cardiac regeneration. 其中包括优化细胞递送方法, improving cell retention and survival, and enhancing the paracrine effects of MSCs. 此外, the standardization of MSC preparation and characterization is crucial to ensure consistency and reproducibility of therapeutic outcomes.

MSCs hold great promise as a novel therapeutic approach for cardiac repair. Preclinical and clinical studies have demonstrated the ability of MSCs to improve cardiac function, 减少梗塞面积, 并促进血管生成. 然而, further research is needed to optimize cell delivery, 增强细胞存活率, and standardize MSC preparation. With continued advancements in this field, MSC-based cardiac regeneration has the potential to revolutionize the treatment of heart failure and other cardiovascular diseases.
