Load-bearing, mechanically active tissues are routinely subjected to non-linear mechanical deformations. Consequently, these tissues exhibit complex mechanical properties and unique tissue organizations. Successful engineering of mechanically active tissues relies on the integration of the mechanical sensing mechanism found in the native tissues into polymeric scaffolds. Intelligent biomaterials that closely mimic the structural organizations and multi-scale responsiveness of the natural extracellular matrices (ECM), when strategically combined with multipotent cells and dynamic culture devices that generate physiologically relevant physical forces, will lead to the creation of artificial tissues that are mechanically robust and biologically functional.
承受负荷的机械活性组织通常会经历非线性机械变形。因此,这些组织表现出复杂的力学性能和独特的组织结构。成功构建机械活性组织依赖于将天然组织中的机械传感机制整合到聚合物支架中。当智能生物材料与多能细胞以及能产生生理相关物理力的动态培养装置进行策略性结合时,若能紧密模拟天然细胞外基质(ECM)的结构组织和多尺度响应性,将有助于创建出机械性能强健且具有生物学功能的人工组织。
