Maximum intensity projection showing dorsal vasculature of the first gill arch of a CUBIC-cleared adult kdrl:mCherry zebrafish. Fluorescent signal was pseudocoloured using the PBIYC lookup table in ImageJ. Analysis of this endothelial reporter enabled detailed mapping of gill vascular development and revealed distinct medial and lateral filament types. Credit text to the journal Development.

I used to get imposter syndrome when sharing other people’s stuff for #ZebrafishZunday. I got over it by thinking that if more people (whether it be a friend, family member or even a grant reviewer) see an awesome image and think zebrafish are cool, it collectively makes our lives/research easier.

The development of a single zebrafish retina captured on a light sheet microscope approx. every 12 hours from 1.5 days to 3.5 days after birth of the embryo. The retinal ganglion cells are labelled with Ath5:RFP (magenta) the amacrine and horizontal cells are labelled with Ptf1a:YFP (yellow) and the photoreceptors and bipolar cells are labelled with Crx:CFP (cyan). The image was created in the Norden lab at the MPI-CBG, Dresden. Credit text to Wikimedia Commons.
