小鼠胚胎是研究人类心脏发育和先天性心脏缺陷调控机制的既定模型。由于培养的小鼠胚胎对任何操作和环境波动都非常敏感,因此控制小鼠胚胎心脏功能的改变是非常具有挑战性的,这是哺乳动物心脏生物力学研究的主要障碍。这篇手稿首次介绍了培养的小鼠胚胎的心脏动力学和血液动力学的光遗传操作。光遗传起搏与4D(3D+Time)OCT结构和多普勒成像相结合,表明在光遗传起搏下胚胎心脏可以有效地工作并产生强大的血流。这项研究表明,该方法是一种强大的工具,可以在实时可视化下对心脏动力学和血流进行快速、一致、可逆的控制,使各种实时心脏生物力学研究能够更好地了解人类的正常心脏发生和先天性心脏病。
The mouse embryo is an established model for investigation of regulatory mechanisms controlling cardiac development and congenital heart defects in humans. Since cultured mouse embryos are very sensitive to any manipulations and environmental fluctuations, controlled alterations in mouse embryonic cardiac function are extremely challenging, which is a major hurdle in mammalian cardiac biomechanics research. This manuscript presents first optogenetic manipulation of cardiodynamics and hemodynamics in cultured mouse embryos. Optogenetic pacing was combined with 4D (3D+Time) OCT structural and Doppler imaging, demonstrating that embryonic hearts under optogenetic pacing can function efficiently and produce strong blood flows. This study demonstrates that the presented method is a powerful tool giving quick, consistent, reversible control over heart dynamics and blood flow under real time visualization, enabling various live cardiac biomechanics studies toward better understanding of normal cardiogenesis and congenital heart defects in humans.
