我们开发了一种从细胞骨架的共焦荧光显微镜图像重建细胞几何形状的方法。在该方法中,区域生长被实施了两次。首先,将其应用于细胞外区域,以将其与细胞内非细胞骨架区域区分开来,这些区域在荧光显微镜图像中均呈黑色,然后应用于细胞区域以进行细胞识别。形态参数分析揭示了与细胞骨架破坏相关的细胞形状的显着变化,这为了解细胞骨架在维持细胞形状中的机械作用提供了见解。所提出的分割方法有望用于研究内部细胞骨架结构的细胞形态变化。
We developed a method to reconstruct cell geometry from confocal fluorescence microscopy images of the cytoskeleton. In the method, region growing was implemented twice. First, it was applied to the extracellular regions to differentiate them from intracellular noncytoskeletal regions, which both appear black in fluorescence microscopy imagery, and then to cell regions for cell identification. Analysis of morphological parameters revealed significant changes in cell shape associated with cytoskeleton disruption, which offered insight into the mechanical role of the cytoskeleton in maintaining cell shape. The proposed segmentation method is promising for investigations on cell morphological changes with respect to internal cytoskeletal structures.
