包括创伤性脑损伤、中风、原发性和转移性脑肿瘤以及神经退行性疾病在内的神经系统疾病影响着全世界数百万人。疾病进展伴随着大脑微环境的变化,但这些生物化学,生物物理和细胞特性的变化如何有助于修复结果或持续变性在很大程度上是未知的。组织工程方法可用于开发体外模型,以了解大脑微环境如何促进与神经系统疾病相关的病理生理过程,并且还可以提供促进体内愈合和再生的结构。在这个角度,我们总结了正常和病理生理状态下大脑微环境的特征,并强调了模拟这种环境来模拟疾病,研究神经干细胞生物学和促进再生愈合的策略。我们讨论了目前的局限性和由此产生的机会,以开发组织工程工具,更忠实地概括方面的大脑微环境在体外和体内的应用。
Neurological disorders including traumatic brain injury, stroke, primary and metastatic brain tumors, and neurodegenerative diseases affect millions of people worldwide. Disease progression is accompanied by changes in the brain microenvironment, but how these shifts in biochemical, biophysical, and cellular properties contribute to repair outcomes or continued degeneration is largely unknown. Tissue engineering approaches can be used to develop in vitro models to understand how the brain microenvironment contributes to pathophysiological processes linked to neurological disorders and may also offer constructs that promote healing and regeneration in vivo. In this Perspective, we summarize features of the brain microenvironment in normal and pathophysiological states and highlight strategies to mimic this environment to model disease, investigate neural stem cell biology, and promote regenerative healing. We discuss current limitations and resulting opportunities to develop tissue engineering tools that more faithfully recapitulate the aspects of the brain microenvironment for both in vitro and in vivo applications.
