Phase imaging with a high-resolution wavefront sensor is a useful setup for biological imaging. Our setup is based on a quadriwave lateral shearing interferometer mounted on a non-modified transmission white-light microscope. We propose here to study long-time duration imaging on different type of adherent cells: green monkey kidney COS7 cells, human breast epithelial MCF10A cells, and human breast cancer derived from MDA-231 cells. This study permits a enhanced visualization of the whole cell life at different levels of confluence. Post treatments on phase-shift images are proposed and become very interesting for enhanced visualization of small details and thresholding.
