Mesenchymal stem cells (MSCs) have been widely used in the fields of tissue engineering and regenerative medicine due to their self-renewal capabilities and multipotential differentiation assurance. However, capitalizing on specific factors to precisely guide MSC behaviors is the cornerstone of biomedical applications. Fortunately, several key biophysical and biochemical cues of biomaterials that can synergistically regulate cell behavior have paved the way for the development of cell-instructive biomaterials that serve as delivery vehicles for promoting MSC application prospects. Therefore, the identification of these cues in guiding MSC behavior, including cell migration, proliferation, and differentiation, may be of particular importance for better clinical performance. This review focuses on providing a comprehensive and systematic understanding of biophysical and biochemical cues, as well as the strategic engineering of these signals in current scaffold designs, and we believe that integrating biophysical and biochemical cues in next-generation biomaterials would potentially help functionally regulate MSCs for diverse applications in regenerative medicine and cell therapy in the future.
间充质干细胞(MSCs)因其自我更新能力和多能分化特性,已在组织工程和再生医学领域得到广泛应用。然而,利用特定因素精确引导间充质干细胞的行为是生物医学应用的基石。幸运的是,生物材料的几个关键生物物理和生化线索能够协同调节细胞行为,为具有细胞指导作用的生物材料的发展铺平了道路,这类生物材料可作为促进间充质干细胞应用前景的递送载体。因此,识别这些引导间充质干细胞行为的线索,包括细胞迁移、增殖和分化,对于更好的临床效果可能尤为重要。本综述旨在全面系统地了解生物物理和生化线索,以及当前支架设计中这些信号的策略性工程,我们相信在下一代生物材料中整合生物物理和生化线索可能有助于在未来的再生医学和细胞治疗中对间充质干细胞进行功能调控,以实现多种应用。
