Growing cell-based myocardial therapies which could lead to successful myocardial repair attracts medical interest. Even more intriguing is the observation that MSCs appears to be a more potent material among kinds of stem cells for the transplantation, the mechanism for this benefit remains unclear. However, the therapeutic contribution of MSCs to myocardial repair can be caused by multiple factors including: direct differentiation into cardiac tissue including cardiomyocytes, smooth muscle cell, and vascular endothelial cells; secreting a variety of cytokines and growth factors that have paracrine activities; spontaneous cell fusion; and stimulating endogenous repair. In addition, MSCs possess local immunosuppressive properties, and MSCs mobilization is widely used clinically for transplantation. We will discusses the potential mechanisms of MSCs repair for ischemic heart diseases.
能够成功实现心肌修复的基于细胞的心肌治疗方法日益受到医学关注。更令人感兴趣的是,在各类干细胞中,间充质干细胞似乎是用于移植的更具潜力的材料,但其产生这种优势的机制仍不清楚。然而,间充质干细胞对心肌修复的治疗作用可能由多种因素引起,包括:直接分化为心脏组织,如心肌细胞、平滑肌细胞和血管内皮细胞;分泌具有旁分泌活性的多种细胞因子和生长因子;自发细胞融合;以及刺激内源性修复。此外,间充质干细胞具有局部免疫抑制特性,并且间充质干细胞动员在临床上广泛用于移植。我们将探讨间充质干细胞修复缺血性心脏病的潜在机制。
