摘要
心力衰竭代表了具有挑战性的临床和公共卫生问题,并且与显着的发病率和死亡率相关。机械地,心肌细胞的丧失导致失代偿的心室重塑,其最终发展为心力衰竭。旨在补充功能性心肌细胞的再生医学被认为是有效治疗心力衰竭的有前途的方法。在过去的几十年中,对心脏再生的研究揭示了心肌细胞增殖的调节网络。最近,研究工作已针对用于心脏再生的非心肌细胞,包括心脏成纤维细胞,心外膜细胞,内皮细胞,干/祖细胞和免疫细胞。心脏成纤维细胞不仅显着影响细胞外基质沉积的组成,其对心肌细胞的功能和增殖至关重要,而且还直接转化为心肌细胞。心外膜在功能上是重要的,因为它通过心外膜 - 间充质转化参与心脏发育和再生。此外,发现几种免疫细胞谱系散布在心脏组织中。发现免疫细胞浸润与炎症反应相结合可刺激损伤后新生小鼠心脏的再生反应。在这篇综述中,我们提出并讨论了非心肌细胞研究的最新进展,这些研究直接调节出生后心脏再生过程中心肌细胞的增殖和分化,试图提供有关治疗心力衰竭的潜在靶点的信息。

摘要: Heart failure represents a challenging clinical and public health problem and is associated with significant morbidity and mortality. Mechanistically, loss of cardiomyocytes leads to decompensated ventricular remodeling, which eventually progresses to cardiac failure. Regenerative medicine aimed to supplement functional cardiomyocytes is supposedly a promising approach for the effective treatment of heart failure. Over the past decades, investigations on heart regeneration have revealed the regulating networks of cardiomyocyte proliferation. Recently, the research effort has been directed to non-cardiomyocytes for heart regeneration, including cardiac fibroblasts, epicardial cells, endothelial cells, stem/progenitor cells, and immune cells. Cardiac fibroblasts not only substantially influence the composition of extracellular matrix deposition which is vital for the function and proliferation of cardiomyocytes, but also directly convert into cardiomyocytes. The epicardium is functionally important since it is involved in the cardiac development and regeneration via epicardial-mesenchymal transformation. Moreover, several immune cell lineages are found to be interspersed in heart tissue. Immune cell infiltration in combination with inflammatory reaction is found to stimulate the regenerative response in neonatal mouse heart after injury. In this review, we presented and discussed recent development in the studies on non-cardiomyocytes that directly regulate cardiomyocyte proliferation and differentiation during postnatal cardiac regeneration, with an attempt to provide information on the potential targets for the treatment of heart failure.
