We present a reproducible protocol for fabrication of polyacrylamide (PAA) hydrogel-based nano-patterns and nano-textures with a wide range of elastic rigidities to study fundamental cell behaviors, such as mechanosensitivity and motility. We explore the benefits of this protocol by successfully testing the compatibility of the PAA platforms with super-resolution microscopy, which is largely unavailable with platforms of nano-scale textures made from different polymers. We also utilized soft and rigid nano-textures to study the mechanosensing basis of T cell behavior and phenotype. For complete information on the generation and use of this protocol, please refer to Tabdanov et al. (2018b).
我们提出了一种可重现的聚丙酰胺(PAA)水凝胶基纳米图案和纳米纹理的制造方案,该方案具有广泛的弹性硬度范围,可用于研究基本的细胞行为,如机械敏感性和运动性。我们通过成功测试 PAA 平台与超分辨率显微镜的兼容性,探索了该方案的优势,而这种兼容性在使用不同聚合物制成的纳米级纹理平台上是很难实现的。我们还利用软质和硬质纳米纹理来研究 T 细胞行为和表型的机械传感基础。有关该方案的生成和使用的完整信息,请参考 Tabdanov 等人(2018b)。
