Skeletal muscle has an innate regenerative capacity to restore their structure and function following acute damages and injuries. However, in congenital muscular dystrophies, large volumetric muscle loss, cachexia, or aging, the declined regenerative capacity of skeletal muscle results in muscle wasting and functional impairment. Recent studies indicate that muscle mass and function are closely correlated with morbidity and mortality due to the large volume and location of skeletal muscle. However, the options for treating neuromuscular disorders are limited. Biomedical engineering strategies such as nanotechnologies have been implemented to address this issue.In this review, we focus on recent studies leveraging nano-sized materials for regeneration of skeletal muscle. We look at skeletal muscle pathologies and describe various proof-of-concept and pre-clinical studies that have used nanomaterials, with a focus on how nano-sized materials can be used for skeletal muscle regeneration depending on material dimensionality.Depending on the dimensionality of nano-sized materials, their application have been changed because of their different physical and biochemical properties.Nanomaterials have been spotlighted as a great candidate for addressing the unmet needs of regenerative medicine. Nanomaterials could be applied to several types of tissues and diseases along with the unique characteristics of nanomaterials. However, when confined to muscle tissue, the targets of nanomaterial applications are limited and can be extended in future research.
骨骼肌具有先天的再生能力,可以在急性损伤后恢复其结构和功能。然而,在先天性肌肉营养不良、大量肌肉损失、恶病质或衰老的情况下,骨骼肌的再生能力下降会导致肌肉萎缩和功能障碍。最近的研究表明,由于骨骼肌的体积大和位置,肌肉质量和功能与发病率和死亡率密切相关。然而,治疗神经肌肉疾病的选择有限。生物医学工程策略,如纳米技术,已经被应用来解决这个问题。在这篇综述中,我们重点介绍了最近利用纳米材料来再生骨骼肌的研究。我们着眼于骨骼肌病理学,并描述了各种基于概念验证和临床前的研究,这些研究都使用了纳米材料,重点关注纳米材料如何根据材料的维度来用于骨骼肌再生。根据纳米材料的维度,由于其不同的物理和生化特性,它们的应用已经发生了变化。纳米材料作为解决再生医学未满足需求的候选者备受关注。纳米材料可以应用于多种类型的组织和疾病,以及纳米材料的独特特性。然而,当局限于肌肉组织时,纳米材料应用的目标是有限的,可以在未来的研究中扩展。
