Fibroblasts undergo significant morphological and functional changes in response to specific environmental cues, adopting a novel phenotype when sustaining transformative activation in wound healing and cancerous processes. The aim of this project is to characterize cytoskeletal reorganization in both control fibroblasts’ (CFs) and cancer-associated fibroblasts’ (CAFs) activation. To achieve this, we propose a novel method based on the extraction of biophysical biomarkers from epifluorescence images of the cytoskeleton of individual fibroblasts, obtained from a patient with lung cancer and activated using TGF-β. These biophysical outputs were also used to identify CAFs subpopulations. While non-tumoral fibroblasts experience larger morphological changes characterized by an increase in area and the acquisition of a robust network of actin fibers, CAFs exhibited sustained larger areas throughout the process regardless of TGF- β administration, amongst other ...
