A Guide to Using Microscopy for Drosophila (Fruit Fly) Research

The fruit fly, typically Drosophila melanogaster, has been used as a model organism for over a century. One reason is that many disease-related genes are shared between Drosophila and humans. It is…

A Guide to Zebrafish Research

To obtain optimal results while doing zebrafish research, especially during screening, sorting, handling, and imaging, seeing the fine details and structures is important. They help researchers make…

Essential Guide to Ultramicrotomy

When studying samples, to visualize their fine structure with nanometer scale resolution, most often electron microscopy is used. There are 2 types: scanning electron microscopy (SEM) which images the…
Developing embryos of different species at different stages during the elongation of their posterior body axis, from left to right in developmental time. The labelled regions in red depict a region of undifferentiated cells called the tailbud, with the corresponding region generated from that tissue shaded in grey. Upper row: lamprey; middle row: catshark; bottom row, zebrafish. This figure has been adapted from the following publication: Steventon, B., Duarte, F., Lagadec, R., Mazan, S., Nicolas, J.-F., & Hirsinger, E. (2016). Species tailoured contribution of volumetric growth and tissue convergence to posterior body elongation in vertebrates. Development, 2016. 143(10):1732-41
