单层细胞压缩力刺激系统

细胞被均匀地限制/压缩在两个亚微米分辨率的两个平行表面之间。

不同的限制高度（例如1um – 300um）

允许长期细胞培养和细胞增殖，同时保持对封闭的完美控制

与高分辨率光学显微镜系统兼容

可以处理足够多的细胞以进行完整的基因表达分析

可与生物功能化的微结构化底物和/或不同的基质（几何形状控制）结合使用

可以与凝胶结合（硬度控制）

兼容任何细胞培养底物（培养皿至96孔板）

应用：

Cell migration 2.5D, migration and interaction of non-adhesive cells, cell squeezing, imaging of flat cells (organelles aligned in 2D), super-resolution video-microscopy (organelles move less), contractility assay, etc

Confinement illustration
HeLa cells: not confined, 5 ?m, 3 ?m.
