Project description

Lens-less video microscopy has made it possible to remove certain limits in observation of cell, allowing for the dynamic observation of cellular life, both microscopically and mesoscopically, over a wide field of view and over time periods ranging from a few days to several weeks. Furthermore, it enables to evaluate cell-to-cell variability using a very large number of cells. Based on this approach we recently started a new quantitative study of the human cell cycle (cell growth and proliferation) observing the kinetics of thousands of cells without any synchronization or labelling, over a wide field of (29.4 mm²) and over periods of up to several days (several cell cycles), and with a fairly rapid acquisition rate (5 min). Thus, we hope to better characterize the human cell cycle of both healthy and cancerous cell.
