On day 95 of LMB365 we have a picture by Katja Röper in the Cell Biology Division. This image shows the flat epithelial patch of cells in the Drosophila embryo that will form the tubes of the salivary glands over a the time span of a few hours. The cell membranes are labelled and the image shows cell outlines at three different depths through the cells, each depth in a different shade of colour. This visualisation therefore allows an appreciation of 3D cell shapes.
