The design of hyaluronic acid (HA)-based hydrogel scaffolds to elicit highly controlled and tunable cell response and behavior is a major field of interest in developing tissue engineering and regenerative medicine applications. This review will begin with an overview of the biological context of HA, which is needed to better understand how to engineer cell-matrix interactions in the scaffolds via the incorporation of different types of signals in order to direct and control cell behavior. Specifically, recent methods of incorporating various bioactive, mechanical and spatial signals are reviewed, as well as novel HA modifications and crosslinking schemes with a focus on specificity.
设计基于透明质酸(HA)的水凝胶支架以引发高度可控和可调的细胞反应及行为,是组织工程和再生医学应用开发中一个主要的研究领域。本综述将首先概述HA的生物学背景,这对于更好地理解如何通过在支架中引入不同类型的信号来构建细胞-基质相互作用,从而指导和控制细胞行为是必要的。具体而言,本文将综述近期整合各种生物活性、力学和空间信号的方法,以及重点关注特异性的新型HA修饰和交联方案。
