Fig. 4: The 3D segmentation results of EmbSAM for the drastic shape dynamics of dividing cells and newborn daughters (non-transparent), as well as their squeezed neighbors (semi-transparent) at 10-second intervals.
From: EmbSAM: cell boundary localization and Segment Anything Model for fast images of developing embryos
A E cell division that squeezes ABplp, in accordance with Supplementary Movie 6. B ABpr cell division that squeezes C, in accordance with Supplementary Movie 7. The swapped cell-cell contact interface orientation originating from the hard cell and pointing the soft cell is highlighted by the starting and ending moments of the top three rows. For (A, B), the developmental time is shown, with the moment of complete cell nuclei separation as time zero. C, D Curves of cell-cell contact interface curvature with sign changed over time, corresponding to (A, B) respectively. Data: the embryo sample “Emb5”. For (A–D), the developmental time is shown, with the moment of complete cell nuclei separation as time zero. Source data: Supplementary Data 9 for (C) and Supplementary Data 10 for (D).
