Take a break from doom-scrolling and watch this cool membrane animation!

1/4 Our @biorxivpreprint, 'Origin of Ewing Sarcoma by Embryonic Reprogramming of Neural Crest to Mesoderm' is now available on bioRxiv! In this study, we explore the enigmatic origin of Ewing sarcoma using our zebrafish genetic cancer models. We revealed that neural crest cells

PI3K dependent rearrangement of the actin cytoskeleton following the addition of Class I PAK kinase-inhibitor. Please read about it in our pre-print!

The next Ethel Browne Harvey Postdoc Seminar is Friday, October 11 at 3 pm Eastern Time with Leah Greenspan @LJGreenspan @NIH and Ben Cox @beeeencox @ucdavis. Register today and join us. https://t.co/cn6m4sLVvL #SDBPostdocSeminar

Registration is LIVE! We are very excited to announce the Inaugural Quantitative Fluorescence Lifetime Imaging Microscopy (QFLIM) workshop at NIH in Bethesda co-organized by Jay Knutson (NIH) and Chris Combs (NIH), on November 7th, 2024. Registration here; https://t.co/a5yM1G2Mud

It's #MicroscopyMonday, so let's take a look into the 🔬 with this @NikonSmallWorld image of an adult transgenic zebrafish head. Blood vessels (blue), lymphatic vessels (yellow), and the skin and scales (magenta). 4x magnification Credit: Daniel Castranova and Brant Weinstein

“Chronic disease”? After we debunked MMR-autism links he went to thimerosal; when that fell he went to overwhelming the immune system; next alum; then infertility; out of desperation he made up chronic disease, even he doesn’t know what that is. It’s all fake pseudoscience.

We love to see #NikonSmallWorld images making the rounds in the real world! Some of our winners' incredible images have been featured by the @USPS in its #LifeMagnifiedStamps collection. Have you seen or used any of these stamps to send a letter? Let us know in the comments! 📬

The newest lymphoid structure in teleosts (the axillary lymphoid organ) has just been reported by @dancastranova @vg_biomarina Aurora Kraus et al led by the Weinstein lab. Check this paper with stunning imaging (as always)!

Take a look at our preprint for more cool images and movies. A HUGE thanks to Brant, @ZebrafishMK and @aurora_kraus, as well as all of our AWESOME collaborators and coauthors, some are on Twitter - @vg_biomarina @DNLumbantobing @m_marvel @KedarNarayan2 @TFordRobertson

Finally, in fish with T-cell acute lymphoblastic leukemia, ALO’s become highly infiltrated with leukemic cells. A big thanks to Kimble Fraser’s group for this!

We looked at several different immune cells in the ALO, here are B-cells.

Here is a movie showing immune cells crawling along the reticular network in the ALO.
