This image by MDI Bio Lab's Travis Carney is a #drosophila larval brain. Neural stem cells and neurons are marked, including axons that project into the brain. The flare in the center of each lobe is part of a learning and memory center in flies.

In developing embryos, cells move a lot! Plenty of that movement is random. Is random cell mixing a feature or bug for tissue patterning? Turns out, it’s both! Excited to share the 1st preprint from my postdoc w/ Sean Megason @seanemcgeary.bsky.social and Allon Klein. 1/20 doi.org/10.1101/2025...

How can we see the cells that make up a living organism? Membrane-localising tags can drive fluorescent proteins to the cell's outer membrane, making their outlines visible. But the tags don't work well in all organisms. How do you find one for your species of interest? 🧵

Cells can form patterns within themselves just like embryos do. How? Connie Yan's new preprint shows how the anterior-posterior cytoskeleton pattern in Stentor is dictated by regionalized scaffolding proteins

Branching morphogenesis is fundamental to animal development, shaping complex organs like lungs, kidneys, and vascular networks. Gills are another highly branched organ. Yet, the developmental processes behind gill formation in zebrafish remain poorly understood.
