Microscopy image sequences and annotated kymographs of laser ablation experiments in Drosophila embryos
<p><strong>Content</strong></p> <p>This dataset contains 15 2D time-lapse fluorescence microscopy image sequences recorded with confocal laser-scanning microscopy. Each movie shows an epithelial tissue laser nanoablation experiment conducted in a Drosophila embryo.</p> <p>For each sequence, the dataset contains kymographs (one-dimensional space-time plots) of a supracellular cable that is cut during the ablation, and manually created tracks of visible features, such as the resulting cut ends. These tracks allow to estimate, for instance, recoil velocities of the cut tissue and may be used to evaluate automated methods for estimating said velocities.</p> <p>This dataset is used in the manuscript to evaluate various variational approaches for joint motion estimation and source identification:</p> <p>L. F. Lang, N. Dutta, E. Scarpa, B. Sanson, C.-B. Schönlieb, and J. Étienne. Joint Motion Estimation and Source Identification using Convective Regularisation with an Application to the Analysis of Laser Nanoablations. 2019.</p> <p><strong>Description</strong></p> <p>The movies depict a square region of approximately <span class="math-tex">\(42.2 \times 42.2 \, \mathrm{\mu m}^{2}\)</span> at a spatial resolution of <span class="math-tex">\(250 \times 250\)</span> pixels. A typical sequence contains between 60 and 100 frames. They temporal interval between recorded frames was <span class="math-tex">\(727.67 \, \mathrm{ms}\)</span>.</p> <p>Each sequence features cell membranes labelled with E-cadherin:GFP and shows a single plasma-induced laser nanoablation. The destructed tissue region is roughly of <span class="math-tex">\(2 \, \mathrm{\mu m}\)</span> length. This ablation is expected to have a width of the order of the size of one pixel. During the ablation the acquisition is paused, resulting in a black image.</p> <p>For the used microscopy techniques and for the preparation of flies, as well as for the details of the laser ablation method, see the paper:</p> <p>E.
