Cell dynamics during late dispersed phase (Wourms’ stage 20). The second part of the dispersed phase is characterized by the presence of a larger number of EL green or red cells as opposed to early dispersed phase (Fig. 4). (a, b) Cell tracking. EVL cells are visualized as large white dots, while EL green and red cells as small green and red dots, respectively. All detected cells were tracked over time. c Quantification of the numbers of each type of cell over time. Note that the number is relatively constant for more than 10 h, while still moving. The images and graph refer to the acquired portion of the embryos, equivalent to the top superior hemisphere
