And it's off! Sepand @rastapopolus.bsky.social kicks off the 1st German Fish Meeting at the COS Heidelberg, with three days full of talks, chats and community-building 🧪🐟
An auditorium full of people. The pic is taken from the presenter's POV, so you can see Sepand and some of the public

Proud to share our new paper in EMBO Reports! 🧬 How does a cell "decide" to become lymphatic vs blood endothelium? Turns out it's not just which genes switch on — it's how the genome folds around them. 💥

The topologically associating domains (TADs) and chromatin accessibility of lymphatic endothelial cells diverge from those of blood endothelial cells. These differences underlie the activation of LEC-specific regulatory networks governing cell identity and involving genes linked to lymphatic disease.

Blood vessels guide immune cells to metastases: Researchers at DKFZ and Medical Faculty Mannheim of Heidelberg University have now identified specialized endothelial cells that enable an effective immune defense against cancer metastases in the liver.

Blood vessels guide immune cells to metastases
It has long been suspected that endothelial cells, the specialized cells lining the inner walls of blood vessels, play a key role in determining how the body’s immune system responds to tumors. Resear...

Whole-embryo spatial transcriptomics at subcellular resolution from gastrulation to organogenesis
Gene expression patterns underlie development, but their systematic detection in whole embryos has remained elusive. We introduce a whole-embryo imaging platform using multiplexed error-robust fluores...

Forschende vom DKFZ haben genauer entschlüsselt, wie Zellen Entzündungsreaktionen steuern. Sie zeigten, dass Zellen zwei unterschiedliche Strategien nutzen, um Entzündungsgene exakt zu steuern und damit die Entzündungsreaktion präzise zu dosieren. @karsten-rippe.bsky.social

#KnowYourZDM: In 2019, a 10-year-old patient w/ a life-threatening lymphatic disorder was losing hope. Zebrafish to the rescue! Scientists created zebrafish with the same gene mutation and found a melanoma drug that fixed the fish. Then, doctors used the same drug on the patient to save his life! 🧪
Zebrafish are an excellent model for studying the development and function of blood and lymphatic vessels. Research in zebrafish has even led to treatments for lymphatic disorders in people. This image, taken using a powerful microscope that uses lasers to illuminate the fish, shows blood vessels (magenta) and lymphatic vessels (green) in the eye and head of an anesthetized, 6-week-old, transgenic zebrafish.

It is with great sadness that we heard of John Gurdon’s passing this week. Not just one of our 100 extraordinary biologists, but truly one of a kind, he was a pioneer, whose vision and personality inspired biologists worldwide.
