Fish close-up

Picture of the week This group of cells represents an interesting example of organ formation where cells simultaneously move and change their shapes in a highly coordinated manner.

Tracing the origins of cells

Science Researchers from the Sharpe group at EMBL Barcelona have published a method to track the developmental history of a cell using the gene editing tool CRISPR–Cas9, but without the need to create transgenic organisms.

Skin mosaic

Picture of the week This beautiful mosaic of mostly hexagonal cells is the outer skin layer of a zebrafish larva as seen under a microscope. Each skin cell exhibits a unique pattern of actin ridges. Actin is a family of globular multifunctional proteins found in almost all eukaryotic cells. Actin forms microfilaments,…

The zebrafish earned its stripes

Picture of the week Despite missing the characteristic stripes one would expect from a zebra – or a zebrafish – the fractals in this Picture of the Week show a zebrafish; or at least some cells in a zebrafish embryo, a few hours after fertilisation. Zebrafish are not only popular aquarium fish, they are also an…

Without a trace

Science Migrating cells, it seems, cover their tracks not for fear of being followed, but to keep moving forward. Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have now shown that cells in a zebrafish embryo determine which direction they move in by effectively…

Digital Embryo gains wings

Science The scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, who ‘fathered’ the Digital Embryo have now given it wings, creating the Fly Digital Embryo. In work published today in Nature Methods, they were able to capture fruit fly development on film, and were the…
