Abstract

Brain injury often caused irreversible loss of neural tissue and resulted in serious neurological disability. Owing to the extreme complexity of the brain, it is still challenging to regenerate the brain tissue from injury and restore its normal function. Growth factors are critical signaling molecules that promote endogenous neural stem/progenitor cells (NSPCs) proliferation, migration and differentiation, resulting in functional brain recovery from injury. However, the labile nature of growth factor motivated us to develop advanced growth factor delivery strategies to precisely control over its release profile in vivo. In this review, we will discuss growth factor delivery via biomaterials for brain regeneration after injury. This review begins with an overview of some major forms of brain injury. The characteristic properties of growth factors are described to provide a biological basis for their use in the brain regeneration. The specific biomaterials that generally used for delivering growth factor to treat brain injury are also detailed summarized. In particular, we focus on an engineering strategy that promote endogenous repair by creating growth factor concentration gradients in vivo. The last part of the review introduces current challenges and perspectives for growth factor delivery via biomaterials.

基于生物材料的生长因子输送用于损伤后脑再生
脑损伤往往造成神经组织的不可逆损失,并导致严重的神经功能障碍。由于大脑的极端复杂性,使脑组织从损伤中再生并恢复其正常功能仍然具有挑战性。生长因子是促进内源性神经干/祖细胞(NSPCs)增殖、迁移和分化,导致脑功能损伤恢复的关键信号分子。然而,生长因子的不稳定性促使我们开发先进的生长因子递送策略,以精确控制其在体内的释放。在这篇综述中,我们将讨论通过生物材料递送生长因子用于损伤后的脑再生。这篇综述首先概述了一些主要形式的脑损伤。本文描述了生长因子的特性,为其在脑再生中的应用提供了生物学基础。并对目前用于输送生长因子治疗脑损伤的特定生物材料进行了详细的综述。我们特别关注一种通过在体内创造生长因子浓度梯度来促进内源性修复的工程策略。回顾的最后一部分介绍了当前的挑战和前景的生长因子输送通过生物材料。
