Résumé

Based on the current study of the influence of mechanical factors on cell behavior which relies heavily on experiments 目前研究力学因素对细胞行为的影响很大程度上依赖于离体实验,基于此本文研制了一种具有较大均匀应变区域的培养室,其中含有以直线电机为动力,频率高达20 Hz的细胞拉伸加载装置,可对细胞施加力学作用。本文以应变均匀为目标,基底厚度为变量,利用有限元技术对传统培养室的基板底部进行优化,最后构建了切面为“M”型结构的新型培养室三维模型,并采用三维数字图像相关法(3D-DIC)检测应变场和位移场的分布,以验证数值模拟结果。实验结果表明,新型细胞培养室增大了应变加载的准确性和均匀区域,较优化前提高了49.13%~52.45%。另外,利用该新型培养室初步研究了在同一应变、不同加载时间下舌鳞癌细胞的形态变化。综上,本文构建的新型细胞培养室结合了以往技术的优点,可传递均匀精准的应变,以便用于广泛的细胞机械生物学研究。.
