In recent years, human pluripotent stem cell-derived cardiomyocytes (hPSC-CMs) have emerged as a vital cell source for in vitro modeling of genetic cardiovascular disorders, drug screening, and in vivo cardiac regeneration research. Looking forward, the ability to efficiently cryopreserve hPSC-CMs without compromising their normal biochemical and physiologic functions will dramatically facilitate their various biomedical applications. Although working protocols for freezing, storing, and thawing hPSC-CMs have been established, the question remains as to whether they are optimal. In this chapter, we discuss our current understanding of cryopreservation appertaining to hPSC-CMs, and proffer key questions regarding the mechanical, contractile, and regenerative properties of cryopreserved hPSC-CMs.
近年来,人多能干细胞衍生的心肌细胞(hPSC-CMs)已成为用于遗传性心血管疾病体外建模、药物筛选及体内心脏再生研究的重要细胞来源。展望未来,能够在不损害其正常生化和生理功能的前提下高效冷冻保存hPSC-CMs,将极大地促进其在各种生物医学领域的应用。尽管已经建立了hPSC-CMs冷冻、储存和解冻的操作方案,但这些方案是否最优仍有待探讨。在本章中,我们讨论了目前对hPSC-CMs冷冻保存的认识,并提出了有关冷冻保存的hPSC-CMs的力学、收缩和再生特性的关键问题。
