Biomechanical Analysis Of Breast Cancer Cells: A Comparative Study Of Invasive And Non-Invasive Cell Lines Using Digital Holographic Microscopy

This study investigates the biomechanical properties of breast cancer cells, focusing on the invasive MDA-MB-231 and non-invasive MCF-7 cell lines, using phase-shifting digital holographic microscopy and an acousto-holographic system for non-invasive strain measurement. Findings reveal higher strain values in MDA-MB-231 cells, indicative of their aggressive, metastatic nature, compared to lower strain values in MCF-7 cells. This variance in mechanical properties, potentially linked to distinct metabolic states and responses to external stimuli, underscores the role of cellular mechanics in cancer progression. The study advances understanding of breast cancer cell mechanics, highlighting biomechanical analysis as a crucial tool in cancer research and potential therapeutic interventions.
