We report a strategy to rewire cell surfaces for the dynamic control of ligand composition on cell membranes and the modulation of cell–cell interactions to generate three‐dimensional (3D) tissue structures applied to stem‐cell differentiation, cell‐surface tailoring, and tissue engineering. We tailored cell surfaces with bioorthogonal chemical groups on the basis of a liposome‐fusion and ‐delivery
我们报告了一种重新连接细胞表面的策略,用于动态控制细胞膜上的配体组成以及调节细胞间相互作用,从而生成应用于干细胞分化,细胞表面剪裁和组织的三维(3D)组织结构工程。我们基于脂质体融合和递送方法,通过生物正交化学基团对细胞表面进行剪裁,以通过涉及化学选择性缀合和释放的化学方法创建动态,电活性和可切换的细胞组织组装体。可以通过无创,无标签的分析技术来监控和调节修饰细胞表面的每个步骤:激活,缀合,释放和再生。
