缺血性心脏病(IHD)是全球死亡的主要原因。干细胞移植是近几十年来治疗缺血性心脏病的一种有前途的方法。临床前细胞治疗是一种有效的治疗方法,其结果令人鼓舞,包括预防或减少心肌细胞死亡、抑制瘢痕形成、促进血管生成和改善心脏功能。然而,临床研究尚未达到预期的结果,甚至多项临床研究显示矛盾的结果。除此之外,还有许多根本性的难题有待解决,例如,什么是最佳的交付时间和方式?此外,有限的细胞植入和存活、具有挑战性的细胞命运监测以及尚未完全了解的功能机制都是临床转化的障碍。在这里,我们回顾了一些目前的困境,在干细胞为基础的治疗缺血性心脏病,沿着我们的努力和意见,对这些关键问题。
Ischemic heart disease (IHD) is the leading cause of mortality worldwide. Stem cell transplantation has become a promising approach for the treatment of IHD in recent decades. It is generally recognized that preclinical cell-based therapy is effective and have yielded encouraging results, which involves preventing or reducing myocardial cell death, inhibiting scar formation, promoting angiogenesis, and improving cardiac function. However, clinical studies have not yet achieved a desired outcome, even multiple clinical studies showing paradoxical results. Besides, many fundamental puzzles remain to be resolved, for example, what is the optimal delivery timing and approach? Additionally, limited cell engraftment and survival, challenging cell fate monitoring, and not fully understood functional mechanisms are defined hurdles to clinical translation. Here we review some of the current dilemmas in stem cell-based therapy for IHD, along with our efforts and opinions on these key issues.
