Two great new #Zebrafish preprints from the #WeinsteinLab using a new transgenic that reports epigenetic silencing and activation! Great to study epigenetic changes in vertebrates, and we even did an ENU screen. Excellent work by @mmarvel.bsky.social et al. 🧪

We recently described the Axillary Lymphoid Organ (ALO) in the #Zebrafish. It's on the OUTSIDE of the fish, making it great for imaging! Learn more by checking out our paper in @jem.org rupress.org/jem/article-...

Excited to see our work describing an external immune organ in the #zebrafish published in JEM! Big thanks to Aurora Kraus and @zebrafishmk.bsky.social and all of our other amazing collaborators including @edanfoley.bsky.social @biomarina-vg.bsky.social #WeinsteinLab rupress.org/jem/article-... 🧪

We were pulling them through the ice today! First time ice fishing in Maryland. Good to get outside. 🎣

Great opportunity! Research position in the Sheppard Lab at the NIH in Bethesda. Zebrafish + imaging + lymphatic vessels = AWESOME! 🧪🔬🐟

Lateral view of an adult transgenic zebrafish (facing left) shown in three colors. Autofluorescence is shown in gray, faintly showing the scale pattern, the fish outline, and more predominantly showing the fin rays (bones of the fins). Lymphatic vessels are shown in green, with a complex network around the head and eye of the fish, and a herring-bone pattern down the body. Neutrophils, a type of white blood cell, are shown in magenta as tiny speckles all over the fish, with a higher concertation around the eye, behind the operculum (gill cover), and at the base of the tail.

Looking down at the head of a transgenic 17-day-old #zebrafish, blood vessels in magenta, lymphatic vessels in green. Extended depth of focus #WeinsteinLab 🧪🔬
A highly detailed gray image of the dorsal view of a zebrafish head pointing to the left with two large black eyes on either side. A complex network of magenta blood vessels look like tangled spaghetti in the center (brain region) of the image. There are dozens of ameba-shaped green cells around the brain blood vessels and a few well-defined green lymphatic vessels on either side of the head. Protruding from the skin on each side of the head, to the right (posterior) to the eye, there are three volcano-like structures with long, transparent, hair-like projections. These are hair cells that the fish uses to sense changes in water flow.

One reason #Zebrafish are a great research model is because they spawn well in captivity. Eggs are externally fertilized allowing us to watch development as it happens. Here is a slo-mo look at zebrafish spawning. 🧪🐟

Bones, scales, and lymphatic vessels in juvenile #Zebrafish for #FluorescenceFriday #WeinsteinLab 🧪🔬
highly detailed dorsal view of three fish with scales and lymphatic vessels shown in different colors with curved bodies as if the fish were swimming. the two fish on the outside are facing downward, and the fish in the middle is facing upward. the left most fish has magenta scales and green lymphatic vessels, the center fish has blue scales and orange lymphatic vessels, and the right fish has green scales and purple lymphatic vessels.

The first 22 hours of #Zebrafish development. Blood vessels labeled in green #WeinsteinLab 🔬🧪

Glad to see so many scientists over here! 😀 Video: 2 day old #zebrafish dorsal aorta - Fish RBC's are nucleated #WeinsteinLab 🧪 🔬

Let's test out this video feature 🤓 The head and heart of a 2.5-day-old #zebrafish with transgenically labeled blood vessels in green, and red blood cells in magenta. #WeinsteinLab 🔬🧪

This is a max intensity projection of a volume taken with a confocal.  Out of focus light is blocked when optical sections are taken making it sharp.  For more details, check out a description by Hank Green at youtu.be/WsCAAqoJa6Q around 6:20. many software options for this- some free, some paid

Hello Bluesky! This is the eye of an adult #Zebrafish, blood vessels in red and lymphatic vessels in blue.
