近年来发现在人和动物心脏心内膜、心肌、心外膜及肺静脉肌袖存在telocytes,其telopodes插入心内/外膜内皮和心肌束之间及血管和神经末梢周围,形成相互分离而又紧密联系的网络。鉴于其存在的位置及特殊结构,推测其可能作为心脏支持细胞,参与心肌细胞更新和心脏再生等。在细胞信号传导、免疫监督和机械动力传导方面也可能有着巨大的潜能,并可能参与心脏修复和重构过程及心律失常和猝死的发生。
In recent years found in human and animal heart endocardium, myocardium, epicardial and pulmonary vein muscular sleeves present telocytes, the telopodes inserted between the endocardial / epicardial endothelium and myocardial bundles and blood vessels and nerve terminals around the formation of mutual separation Closely linked network. In view of its location and special structure, it is speculated that it may serve as cardiac support cells, involved in myocardial cell renewal and cardiac regeneration. There may also be great potential for cell signaling, immune surveillance and mechanical power transduction, and may be involved in cardiac repair and remodeling processes as well as arrhythmias and sudden death.
