Abstract:
The quantitative analysis of biomechanical profiles at the single-cell level can provide additional information. It is usually not available in traditional cell biology approaches, but may be crucial to assess and understand tumor prognosis and response to chemotherapy. In this study, the on-line changes of cell elastic properties after the addition of cancer target drug LHRH-PE40 were monitored by atomic force microscopy ( AFM) on living HeLa cell surface under physiological condition. The results from AFM based force spectroscopy showed that LHRH-PE40 induced a distinct increase of the cell surface elasticity of HeLa cells. The fluorescence images implied that the target drug LHRH-PE40 would affect the re-organization of cell actions, which led to the increase of the elasticity of HeLa cells.
