Hi BlueSky! For my first #FluorescenceFriday, here's my intro 👋 I study how intestinal neurons and immune cells interact under environmental chemical exposure, using zebrafish larvae as model organism. Check out these #Macrophages and #EntericNeurons! 🐟✨

Meiner Meinung nach ist die Mikroskopie eine der coolsten Methoden in der Wissenschaft, weil sie es uns ermöglicht, das „Unsichtbare“ sichtbar zu machen. Sie hat etwas wirklich Künstlerisches an sich, das wir mit der Gesellschaft teilen können. Seeing is believing. 1/3
