细胞与其细胞外基质(ECM)之间的机械相互作用调节细胞的行为,包括增殖、分化、黏附和迁移。细胞需要ECM的三维(3D)架构支撑来执行生理上真实的功能。然而,目前对细胞-ECM和细胞-细胞机械相互作用的了解主要来自2D细胞牵引力显微镜,即细胞培养在平面基质上。3D细胞牵引显微镜正在出现,用于绘制植入合成或天然衍生纤维凝胶中的单个动物细胞的牵引场。我们在这里讨论3D细胞牵引显微镜的发展,它目前的局限性,以及对这项技术的未来的展望。重点放在将3D细胞牵引显微镜应用于单个肿瘤细胞在胶原凝胶中迁移的策略上。
Mechanical interaction between the cell and its extracellular matrix (ECM) regulates cellular behaviors, including proliferation, differentiation, adhesion, and migration. Cells require the three dimensional (3D) architectural support of the ECM to perform physiologically realistic functions. However, current understanding of cell-ECM and cell-cell mechanical interactions is largely derived from 2D cell traction force microscopy, in which cells are cultured on a flat substrate. 3D cell traction microscopy is emerging for mapping traction fields of single animal cells embedded in either synthetic or natively derived fibrous gels. We discuss here the development of 3D cell traction microscopy, its current limitations, and perspectives on the future of this technology. Emphasis is placed on strategies for applying 3D cell traction microscopy to individual tumor cells migration within collagen gels.
