Electron micrographs of synapses in frogs
<p>This dataset contains transmission electron micrographs of synapses of a frog.<br>It has been published in [1] and has been re-used to evaluate automated synaptic vesicle segmentation in [2].<br>To obtain the data, frog (Rana pipiens) cutaneous pectoris muscles were dissected and mounted in sylgard-lined chambers, in a frog Ringer buffer (115 mM NaCl, 2 mM KCl, 1.8 mM CaCl2, 2.4 mM NaHCO3, pH 7.2). Samples were fixed with 2% glutaraldehyde in frog Ringer, at -2°C for 40-60 minutes, followed by washing, post-fixing with 2% OsO4 in PBS, dehydration through a series of ethanol solutions and propylene oxide, and embedding in Epon resin. A proportion of the vesicles was labeled with precipitated di-amino-benzidine, using a photo-oxidation procedure. The blocks were then sectioned (80-90 nm thickness), and were post-stained with 2% uranyl acetate in a 1:1 ethanol-water mixture (1 minute incubation). Images were acquired using a CM-10 Philips electron microscope, using film negatives. These were enlarged 2.69-fold by transferring to photographic paper (Eastman Kodak Company, Rochester, NY). The paper was scanned at 300 dpi, to obtain the final images.<br>The data is or organized into two different subfolders "train_unlabeled" and "test" that were used for unsupervised domain adaptation and qualitative evaluation respectively.<br>Each folder contains hdf5 files with stacks of electron micrograph, with the image data stored in the internal dataset "raw".</p> <p>References:<br>[1] Rizzoli and Betz, The Structural Organization of the Readily Releasable Pool of Synaptic Vesicles, Science 2004, DOI: 10.1126/science.1094682<br>[2] Muth, Moschref et al., 2024, Preprint to be published</p>
Synapses in transmission electron micrographs
<p>This dataset contains 13 transmission electron micrographs of Schaffer collateral and mossy fiber synapses in organotypic hippocampal slices.<br>The data was published as part of the study [1]. It has been re-used for [2] to evaluate automated synaptic vesicle segmentation.<br>For this data, organotypic slices were prepared from the hippocampi of neonatal mice using the interface protocol and vitrified after 28 day in vitro in culture medium supplemented with 20% (w/v) bovine serum albumin using an HPM100 (Leica) high-pressure freezing device. Automated freeze-substitution and epoxy embedding was performed as previously described (Imig and Cooper, 2017)57. Ultrastructural analysis was performed on 60 nm-thick sections postcontrasted with 1% aqueous uranyl acetate and Reynold’s lead citrate. Electron micrographs were acquired at 20 000 x magnification (pixel size = 0.592 nm) with an 80 kV LEO 912-Omega transmission electron microscope (Zeiss) equipped with a slow scan dual-speed CCD camera “Sharpeye” (Tröndle, Moorenweis, Germany).<br>The data is organized in two different subfolders, "train_unlabeled", which was used for domain adaptation training and "test", which was used for evaluation.<br>Each folder contains the micrographs and, if present, corresponding annotation in hdf5 files.<br>The hdf5 files contain the following internal datasets:<br>- raw: The electron micrograph.<br>- labels/vesicles: The vesicle annotations, annotated in IMOD and export as instance masks (only for the files in "test")<br>- labels/mask: A mask annotation that marks the areas with annotated vesicles (only for ths files in "test")</p> <p>[1] Maus et al., Ultrastructural Correlates of Presynaptic Functional Heterogeneity in Hippocampal Synapses, Cell Reports, 2020, DOI: 10.1016/j.celrep.2020.02.083<br>[2] Muth, Moschref et al., 2024, Preprint to be published</p>
