Asymmetric growth of cancer cell filopodia under electric field stimulation measured by structured illumination nano-profilometry

We use structured-illumination nano-profilometry with sub-diffraction-limit lateral resolution to measure the filopodium dynamics of lung cancer cells under stimulation of DC electric fields. The cathode growth bias and enhanced expression of filopodia are observed.
