Abstract

Stem cell transplantation has emerged as a potential modality in cardiovascular therapeutics due to their inherent characteristics of self-renewal, unlimited capacity for proliferation and ability to cross lineage restrictions and adopt different phenotypes. Constrained by extensive death in the unfriendly milieu of ischemic myocardium, the results of heart cell therapy in experimental animal models as well as clinical studies have been less than optimal. Several factors which play a role in early cell death after engraftment in the ischemic myocardium include: absence of survival factors in the transplanted heart, disruption of cell-cell interaction coupled with loss of survival signals from matrix attachments, insufficient vascular supply and elaboration of inflammatory cytokines resulting from ischemia and/or cell death. This article reviews various signaling pathways involved in triggering highly complex forms of cell death and provides critical appreciation of different novel anti-death strategies developed from the knowledge gained from using an ischemic preconditioning approach. The use of pharmacological preconditioning for up-regulation of pro-survival proteins and cardiogenic markers in the transplanted stem cells will be discussed.

摘要

由于干细胞具有自我更新、无限增殖能力以及跨越谱系限制并呈现不同表型的内在特性,干细胞移植已成为心血管治疗的一种潜在方式。受缺血心肌不利环境中大量细胞死亡的限制,实验动物模型以及临床研究中的心脏细胞治疗结果并不理想。移植到缺血心肌后早期细胞死亡中起作用的几个因素包括:移植心脏中缺乏存活因子、细胞间相互作用的破坏以及基质附着的存活信号丧失、血管供应不足以及缺血和/或细胞死亡导致的炎性细胞因子的产生。本文综述了引发高度复杂细胞死亡形式所涉及的各种信号通路,并对基于缺血预处理方法所获知识开发的不同新型抗死亡策略进行了批判性评价。还将讨论使用药理学预处理上调移植干细胞中促存活蛋白和心脏发生标志物的问题。
