再生生物学主要关注化学因素和转录网络。然而,内源性离子流是细胞行为的关键表观遗传调节因子。生物电信号涉及反馈回路、远程通信、极性和多种尺度上的信息传输。了解内生电压梯度、离子流和电场的作用将有助于基本理解各种形态发生过程以及它们在扰动后强健恢复图案的方法。通过学习调节控制细胞增殖、迁移和分化的生物电信号,我们获得了一套强大的新技术,用于在生物医学环境中操纵生长和模式。本章回顾了生物电信号的独特性质,综述了研究生物电信号的分子策略和试剂,并讨论了再生医学的机会。
Regenerative biology has focused largely on chemical factors and transcriptional networks. However, endogenous ion flows serve as key epigenetic regulators of cell behavior. Bioelectric signaling involves feedback loops, long-range communication, polarity, and information transfer over multiple size scales. Understanding the roles of endogenous voltage gradients, ion flows, and electric fields will contribute to the basic understanding of numerous morphogenetic processes and the means by which they can robustly restore pattern after perturbation. By learning to modulate the bioelectrical signals that control cell proliferation, migration, and differentiation, we gain a powerful set of new techniques with which to manipulate growth and patterning in biomedical contexts. This chapter reviews the unique properties of bioelectric signaling, surveys molecular strategies and reagents for its investigation, and discusses the opportunities made available for regenerative medicine.
