Cardiomyocyte regeneration following cardiac damage is challenging to study because of the inflammatory process, the multiplication of cells in the stroma, and the creation of scar tissue. In addition to the initial damage, the subsequent decrease in cardiac myocytes adds to heart failure. Piezo1 is remarkably understudied in the heart, which may be related to its recent discovery. Despite this, Piezo1 is expressed in a variety of cardiovascular cell populations, notably epithelial cells (EC), cardiac fibroblasts (CF), and cardiac myocytes (CM), in both animal and human samples, with fibroblasts expressing more than myocytes. Researchers have recently shown that disrupting Piezo1 signaling causes defects in zebrafish developing the outflow tract (OFT) and aortic valves. Platelet plasma membranes may provide lipid substrates, such as phosphatidylinositol bisphosphate, that aid in activating the piezo 1 ion channel in the cardiovascular system. In addition, CXC chemokine ligand 8/CXC chemokine receptor 1/2 (CXCL8-CXCR1/2) signaling was identified to establish the proliferation of coronary endothelial cells during cardiac regeneration. Notably, all these pathways are calcium-dependent, and cell proliferation and angiogenesis were necessary to recover myocardial cells. This review will examine the most current findings to understand further how platelet-rich plasma (PRP) and the piezo 1 channel might aid in cardiomyocyte regeneration.
由于炎症过程、基质中细胞的增殖以及瘢痕组织的形成,心脏损伤后的心肌细胞再生研究具有挑战性。除了初始损伤外,随后心肌细胞的减少会加重心力衰竭。Piezo1在心脏中的研究非常少,这可能与其最近才被发现有关。尽管如此,在动物和人类样本中,Piezo1在多种心血管细胞群体中表达,特别是上皮细胞(EC)、心脏成纤维细胞(CF)和心肌细胞(CM),其中成纤维细胞的表达多于心肌细胞。研究人员最近表明,破坏Piezo1信号会导致斑马鱼流出道(OFT)和主动脉瓣发育缺陷。血小板质膜可能提供脂质底物,如磷脂酰肌醇二磷酸,有助于激活心血管系统中的Piezo 1离子通道。此外,已确定CXC趋化因子配体8/CXC趋化因子受体1/2(CXCL8-CXCR1/2)信号在心脏再生过程中促进冠状动脉内皮细胞的增殖。值得注意的是,所有这些途径都依赖于钙,细胞增殖和血管生成对于恢复心肌细胞是必要的。本综述将研究最新发现,以进一步了解富含血小板血浆(PRP)和Piezo 1通道如何有助于心肌细胞再生。
