Transition from early to late dispersed phase. a–h Time lapse showing the transition from a stage with few EL red or green cells could be detected through multiple reactivation and division events up to a relatively stable condition where the number of green EL cells is ~ 5 times their original number. g Quantification of green EL cell numbers over time. The letters a–h correspond to the pictures shown in a–h. Multiple peaks of synchronized proliferation are clearly visible (c, e, g) and divided by phases when cells synchronously enter into G1 phase (d, f, h). The images and graph refer to the acquired portion of the embryos, equivalent to the superior hemisphere
