Segmentation and Morphometric Analysis of Cells from Fluorescence Microscopy Images of Cytoskeletons

Abstract EN

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.
