Abstract:

Cardiovascular diseases (CVDs) are currently the leading cause of death in China. Although current medical interventions can alleviate symptoms and reduce adverse cardiac remodeling, they fail to address the underlying problem of irreversible loss of cardiac tissue. Under certain conditions, stem cells can directionally differentiate into cardiomyocytes. And it is an ideal way to restore normal heart function by treating impaired hearts with pluripotent stem cell-derived cardiomyocytes (PSC-CMs) . During the differentiation of stem cells into cardiomyocytes, multiple transcription factors and signaling pathways follow a certain pattern of expression at different periods, which can be regulated to improve the efficiency of harvesting PSC-CMs. In the last decade or so, the role of non-coding RNA (ncRNA) , especially microRNA (miRNA) , long non-coding RNA (lncRNA) and circular RNA (circRNA) , as critical molecules in the regulation of gene expression, has been extensively investigated. The biological regulatory functions of ncRNAs occur at the epigenetic level and during transcriptional and post-transcriptional levels. The development of the heart is also regulated by ncRNAs. In this review, we outlined the regulatory mechanisms of ncRNAs during cardiomyocyte differentiation and maturation to provide theoretical guidance for more effective acquisition of high-quality PSC-CMs to be used in the clinical treatment of CVDs.

Key words: Stem cells, Cardiomyocytes, Differentiation, non-coding RNA
