Movie 3.

Widefield time-lapse video of cell-like compartment formation in Xenopus egg extracts. Imaged with a widefield epifluorescence microscope and a 5x objective. This movie comprises the complete set of time series images from the experiment shown in Fig. S1B. It shows key events and structures in the compartment formation process. Imaging started 1 min after the extract had commenced room temperature incubation, and therefore the time stamps started from 1 min. Related to Fig. 1.
