  1. The numbers in the first column correspond to the numbering in Fig. 3F. The column “Lineage” contains the consensus lineage name based on the literature and multiple time-lapse recordings. The “Support” column indicates the number of time-lapse recordings with the given cell lineage/the number of total time-lapse recordings analyzed for a given cell type. “Refs” indicates additional support from published literature [23]. The column “Last observed division” refers to the time point at which the last cell division was observed. Since most of the cells in this table show terminal differentiation characteristics, we consider the time of the last observed division being identical to cell cycle exit. The “rID” column contains the reference ID of the given cell type which corresponds to the rID in the tracking files (Additional files 4 and 7 and the tracking files of individual embryos provided in online data repository [28]) and the consensus lineage tree (Additional file 10: Figure S2)
