Induced pluripotent stem cells (iPSCs) are reprogrammed somatic cells by defined factors, and have great application potentials in tissue regeneration and disease modeling. Biomaterials have been widely used in stem cell-based studies, and are involved in human iPSCs based studies, but they were not enough emphasized and recognized. Biomaterials can mimic the extracellular matrix and microenvironment, and act as powerful tools to promote iPSCs proliferation, differentiation, maturation, and migration. Many classic and advanced biofabrication technologies, such as cell-sheet approach, electrospinning, and 3D-bioprinting, are used to provide physical cues in macro-/micro-patterning, and in combination with other biological factors to support iPSCs applications. In this review, we highlight the biomaterials and fabrication technologies used in human iPSC-based tissue engineering to model neuromyopathic diseases, particularly those with genetic mutations, such as Duchenne Muscular Dystrophy (DMD), Congenital Heart Diseases (CHD) and Alzheimer's disease (AD).
诱导多能干细胞(iPSC)是通过特定因子重编程的体细胞,在组织再生和疾病建模方面具有巨大的应用潜力。生物材料已广泛应用于基于干细胞的研究中,也参与了基于人类iPSC的研究,但它们尚未得到足够的重视和认可。生物材料可以模拟细胞外基质和微环境,是促进iPSC增殖、分化、成熟和迁移的有力工具。许多经典和先进的生物制造技术,如细胞片层法、静电纺丝和3D生物打印,被用于在宏观/微观图案化中提供物理线索,并与其他生物因子结合以支持iPSC的应用。在本综述中,我们重点介绍了用于基于人类iPSC的组织工程以模拟神经肌肉疾病,特别是那些具有基因突变的疾病,如杜氏肌营养不良症(DMD)、先天性心脏病(CHD)和阿尔茨海默病(AD)的生物材料和制造技术。
