Abstract

Studies related to low temperature and their effect on cardiomyocytes are essential as hypothermia—like situations have been known to induce arrhythmia or ventricular fibrillation. Till date, several studies have been carried out on animals and their electrophysiological responses have been studied in the form of action potential. However, for a complete assessment of the effect of low temperature, mechanophysiological changes along with electrophysiological changes need to be investigated, at the tissue level. In this study, the effect of culture temperature on cell growth has been studied by measuring the field potential and contractility of human induced pluripotent stem cell-derived cardiomyocytes. This study has the potential to further improve the understanding of low temperature on human cells.

低温对人类诱导多能干细胞衍生心肌细胞(hiPSC-CMs)电生理学和机械生理学的影响
与低温及其对心肌细胞的影响有关的研究至关重要,因为已知类似低温的情况会诱发心律失常或心室颤动。迄今为止,已对动物进行了多项研究,并以动作电位的形式研究了它们的电生理反应。然而,为了全面评估低温的影响,需要在组织水平上对机械生理变化和电生理变化进行研究。本研究通过测量人诱导多能干细胞衍生心肌细胞的场电位和收缩力,研究了培养温度对细胞生长的影响。这项研究有可能进一步提高人们对低温对人类细胞影响的认识。
