Time lapse imaging of the DTC at long (12 h) or short (1 h) intervals reveals growth of individual processes. Dynamics of growth differ between individuals. While average growth is close to linear (green curve in C), some DTCs experience apparent spurts of growth (blue curve in C) while others experience more even, slow growth (red curve in C).
