It was a great pleasure to be a part of this new study from @halinlab.bsky.social focusing on the #Lymphatics in human skin!

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.

#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! πŸ§ͺ

After 7 years and a lot of memories, I've finally decided to retire Zebrafish Rock! on social media. I really want to say it was always positive but I've had a tumultuous experience with the account. Those that make the community more toxic continue to be promoted to positions of power. 1/4
