Figure Lengend Snippet: A . Representative 3D-rendered dendritic segment illustrating how vGAT and gephyrin puncta were categorized for analysis, including colocalized, non-colocalized, and overlapped populations. B. Representative images of cultured hippocampal neurons transfected at DIV7 with expressing GFP alone (Control) or co-expressing GFP with OGT (OGT overexpression). Neurons were analyzed by triple immunofluorescence labeling for GFP (yellow), gephyrin (lilac), and vGAT (green). Scale bar, 5 μm (applies to all images). C. Quantification graphs of the effects of OGT overexpression in neurons on intensity, and size of gephyrin or vGAT puncta (Total, non-colocalization). D. Quantification of inhibitory synapse number (gephyrin and vGAT puncta) showing no significant changes following OGT deletion. E. Quantification of overlapped volume gephyrin and vGAT puncta, showing a significant increase in OGT overexpression neurons. Data are presented as S.E.M (*P < 0.05, **P < 0.01, ***P < 0.001; unpaired Student’s t test).

Figure Lengend Snippet: A. Representative images of cultured hippocampal neurons transfected at DIV7 with GFP alone (Control) or GFP + Cre (OGT-KO). Neurons were analyzed by triple immunofluorescence labeling for GFP (yellow), α-GABA A γ2 (magenta), and vGAT (green). Shown are single-plane and 3D-rendered views of γ2 and vGAT puncta along dendritic segments, with merged images illustrating their spatial relationship. Scale bar, 5 μm (applies to all images). B . Quantification of γ2 and vGAT puncta number per 10 μm dendrite in control and OGT-KO neurons, shown for total and non-colocalized populations. No significant differences were observed . C. Quantification of γ2 puncta intensity and volume (total and non-colocalized with vGAT) showed that OGT-KO neurons exhibited significant increases in γ2 intensity compared with controls. D. Quantification of overlapped γ2–vGAT puncta volume, showing significantly increased overlap in OGT-KO neurons. Data are presented as S.E.M. *P < 0.05, **P < 0.01, ***P < 0.001; unpaired Student’s t test.

Article Title: Timelapse-based 3D reconstruction of blastocysts reveals 3D morphologies of human blastocysts

doi: 10.1038/s41746-025-02028-9

Figure Lengend Snippet: The left panel shows the distributions of each parameter (y-axis: number of blastocysts; x-axis: units of the parameter). The middle panel lists the parameter numbers, names, and definitions. a–c On the right illustrate the definitions of selected 3D morphological parameters. a ICM minor-to-major axis ratio, indicating how elongated the ICM shape is. b Spatial distance between the ICM and TE: R denotes blastocyst radius; d is the distance from the ICM centroid to the blastocyst centroid, reflecting ICM displacement. c Corresponding to parameters 19 and 20, the blastocyst is divided into eight equal quadrants (Q1–Q8) around its centroid. The ICM quadrant (Q ICM ) is defined as the quadrant containing the ICM centroid. These two parameters describe the spatial relationship between the ICM location and the spatial density distribution of TE cells. TE, Trophectoderm; ICM, Inner Cell Mass.
