PURPOSE OF REVIEW The typical remodeling process after cardiac injury is scarring and compensatory hypertrophy. The limited regeneration potential of the adult heart is thought to be due to the post-mitotic status of postnatal cardiomyocytes, which are mostly binucleated and/or polyploid. Nevertheless, there is evidence for cardiomyocyte turnover in the adult heart. The purpose of this review is to describe the recent findings regarding the proliferative potential of mononuclear cardiomyocytes and to evaluate their function in cardiac turnover and disease. RECENT FINDINGS There is overwhelming evidence from carbon-dating in humans and multi-isotope imaging mass spectrometry in mice that there is a very low but detectable level of turnover of cardiomyocytes in the heart. The source of this renewal is not clear, but recent evidence points to a population of mononuclear, diploid cardiomyocytes that are still capable of authentic cell division. Controversy arises when their role in cardiac repair is considered, as some studies claim that they contribute to repair by cell division while other studies do not find evidence for hyperplasia but hypertrophy. Stimulation of the mononuclear cardiomyocyte population has been proposed as a therapeutic strategy in cardiac disease. The studies reviewed here agree on the existence of a low annual cardiomyocyte turnover rate which can be attributed to the proliferation of mononuclear cardiomyocytes. Potential roles of mononucleated cardiomyocytes in cardiac repair after injury are discussed.

单核心肌细胞在心脏周转和再生中的作用。

审查的目的心脏损伤后的典型重塑过程是瘢痕形成和代偿性肥大。成年心脏再生潜力有限被认为是由于产后心肌细胞的有丝分裂状态所致,这些细胞大部分为双核和/或多倍体。然而,有证据表明成年心脏中的心肌细胞更新。这篇综述的目的是描述有关单核心肌细胞增殖潜力的最新发现,并评估它们在心脏更新和疾病中的作用。最近的发现,从人类的碳约会和小鼠的多同位素成像质谱分析中获得了压倒性的证据,即心脏中心肌细胞的周转水平非常低,但可检测到。续约的来源尚不清楚,但是最近的证据表明,单核二倍体心肌细胞群仍然能够进行真正的细胞分裂。考虑到它们在心脏修复中的作用时会引起争议,因为一些研究声称它们通过细胞分裂促进修复,而其他研究则没有发现增生而是肥大的证据。已经提出刺激单核心肌细胞群体作为心脏病的治疗策略。这里回顾的研究同意存在低的年心肌细胞更新率,这可归因于单核心肌细胞的增殖。讨论了单核心肌细胞在损伤后心脏修复中的潜在作用。考虑到它们在心脏修复中的作用时会引起争议,因为一些研究声称它们通过细胞分裂促进修复,而其他研究则没有发现增生而是肥大的证据。已经提出刺激单核心肌细胞群体作为心脏病的治疗策略。这里回顾的研究同意存在低的年心肌细胞更新率,这可归因于单核心肌细胞的增殖。讨论了单核心肌细胞在损伤后心脏修复中的潜在作用。当考虑到它们在心脏修复中的作用时会引起争议,因为一些研究声称它们通过细胞分裂来促进修复,而其他研究则没有发现增生而是肥大的证据。已经提出刺激单核心肌细胞群体作为心脏病的治疗策略。这里回顾的研究同意存在低的年心肌细胞更新率,这可以归因于单核心肌细胞的增殖。讨论了单核心肌细胞在损伤后心脏修复中的潜在作用。已经提出刺激单核心肌细胞群体作为心脏病的治疗策略。这里回顾的研究同意存在低的年心肌细胞更新率,这可以归因于单核心肌细胞的增殖。讨论了单核心肌细胞在损伤后心脏修复中的潜在作用。已经提出刺激单核心肌细胞群体作为心脏病的治疗策略。这里回顾的研究同意存在低的年心肌细胞更新率,这可归因于单核心肌细胞的增殖。讨论了单核心肌细胞在损伤后心脏修复中的潜在作用。
