Issue Information

Front cover: At first glance, it might seem to be a Japanese rock garden (karesansui) with wavy lines in the sand (samon); however, it is actually an electron microscopic photograph of Drosophila midgut epithelium taken with the freeze‐fracture method. The lines that look like samon are smooth septate junctions, which are a kind of occluding junction seen in invertebrates. We thank Prof. Mikio Furuse and Ms. Kyoko Furuse (National Institute for Physiological Sciences) for providing the data and sharing the idea of karesansui. Designed by TRAIS Co., Ltd. (Kobe, Japan).
