Anterior-posterior constraint on Hedgehog signaling by hhip in teleost fin elaboration
Summary: Mutation of hhip in zebrafish induces abundant radial bones of pectoral fins, analogous to those of basal fishes, suggesting the importance of Hedgehog signaling suppression by hhip in teleos...

Hello Bluesky: Long time listener, first time poster! Excited to share the first publication of my Ph.D. work studying the development of appendage shapes in @plosbiology.org! The zebrafish caudal fin is quite distinctive, and we examine the timing and mechanisms of how its shape might come to be!
Caudal fins show great variation in shape between diverse fish species. New research reveals that #developmental cues in embryonic tissues involving the Sonic hedgehog pathway imprint fin #morphology, highlighting a critical window for modulating appendage morphology. 🧪

We take for granted that our hands have two sides and can articulate in an endless number of ways. But what about a fish’s fin? Can a fish know something “like the back of its fin,” or have its future told with a fin palm reading? Check out this bluetorial to find out 👇🧪🧬🐟 doi.org/10.1101/2025...
