Fig. 3: The segmentation results (exemplified by the embryo sample “Emb5”) of EmbSAM for the EMS cell division at 10-second intervals.
From: EmbSAM: cell boundary localization and Segment Anything Model for fast images of developing embryos
A 2D (middle plane) and 3D segmentation results viewed in the imaging direction and highlighted by the dotted cell nuclei and masked cell membranes. Shown are lateral views with the anterior of the embryo to the left. All cell identities at the first and last moments are labeled next to their cell regions. Scare bar: 10 μm. B Monotonic curves of cell surface area, general sphericity, Hayakawa roundness, spreading index, and diameter over time, shown with their data in individual embryo samples (differentially color-coded) as well as averaged over all embryo samples (black) alongside standard deviation (orange shade). C Curves of cell-cell contact area over time, shown with their data in individual embryo samples (differentially color-coded) and in average (black) with standard deviation (orange shade). For (A, B, C), the developmental time is shown, with the moment of complete cell membrane separation as time zero; For (B, C), the durations of all embryo samples are normalized to their average. Source data: Supplementary Data 7 for (B) and Supplementary Data 8 for (C).
