Biomaterial cues can act as potent regulators of cell niche and microenvironment. Epigenetic regulation plays an important role in cell functions, including proliferation, differentiation, and reprogramming. It is now well appreciated that biomaterials can alter epigenetic states of cells. In this study, we systematically reviewed the underlying epigenetic mechanisms of how different biomaterial cues, including material chemistry, topography, elasticity, and mechanical stimulus, influence cell functions, such as nuclear deformation, cell proliferation, differentiation, and reprogramming, to summarize the differences and similarities among each biomaterial cues and their mechanisms, and to find common and unique properties of different biomaterial cues. Moreover, this work aims to establish a mechanogenomic map facilitating highly functionalized biomaterial design, and renders new thoughts of epigenetic regulation in controlling cell fates in disease treatment and regenerative medicine.
生物材料线索可以作为细胞生态位和微环境的有效调节剂。表观遗传调控在细胞功能中起着重要作用,包括增殖、分化和重编程。现在人们已经充分认识到,生物材料可以改变细胞的表观遗传状态。在这项研究中,我们系统地综述了不同生物材料线索(包括材料化学、形貌、弹性和机械刺激)如何影响细胞功能的潜在表观遗传机制,例如核变形、细胞增殖、分化和重编程,以总结每种生物材料线索及其机制之间的差异和相似之处,并找到不同生物材料线索的共同和独特性质。此外,这项工作旨在建立一个机械基因组图谱,以促进高度功能化的生物材料设计,并为疾病治疗和再生医学中控制细胞命运的表观遗传调控提供新的思路。
