✨Jeffrey Farrell is a Stadtman Investigator at the NIH. He has led seminal work constructing single-cell RNAseq atlases for entire embryos using zebrafish. We are excited to host Jeffrey at the #2026SDB in Las Vegas! 🔬

Today on #ModelMonday we have a spotty squid hatchling! 🦑 The longfin inshore squid has huge axons which allowed Hodgkin and Huxley to discover nerve impulses propagate by action potential. Today they are an important model for cephalopod development. 🔬 📷 by Rita Alonaizan

✨ Excited to host invited speaker Roberto Mayor at #2026SDB in Las Vegas! 🎰🃏 His research explores morphogenesis, focusing on how cells migrate, interact, and generate diverse cell types during development. 🧬✨ #devbio

✨ Excited to host invited speaker Alexandra Joyner (@ALJoyner21) at #2026SDB in Las Vegas! 🎰🃏 Her research explores the genetic regulation of development and how signaling pathways shape tissue patterning and organ formation. 🧬✨ #devbio

What can we learn from model organisms? 🧬 🧫 Regeneration (Hydra, Stentor) 🌱 Stem cell niches (plant meristems) 🌸 Patterning (Mimulus) 🐟 Novel structures (sea robins) Diverse systems + fundamental questions. 🔗 doi.org/10.1016/j.ydbi… #ModelMonday

A window into early development! 🔬 2-photon image: Ciona neurula embryo reveals a nuclear SoxB1 (grey) and a membrane Msxb reporter, color-coded along the anterior–posterior axis, highlighting the organization of the developing NS. 📷: Laurence Lemaire #FluorescenceFriday

🧬✨ At #2026SDB in Las Vegas, join us for a talk by Lee Niswander 🎰 Her lab uses mouse embryonic development to uncover how the nervous system, limbs, and other organs form, and how disruptions in these processes lead to major birth defects 🐭🔬

🪱✨ Join us at #2026SDB in Las Vegas to hear from Ricardo Zayas! 🎰 His lab uses freshwater planarians to study how entire organisms regenerate from tiny body fragments 🌱🧬, focusing on adult pluripotent stem cells (neoblasts) that drive tissue renewal and regeneration. 🔬

🐻🦠 Tardigrades💧✨ These microscopic animals can survive extreme conditions by entering a dormant state called cryptobiosis, making them a fascinating model to study stress tolerance, desiccation, DNA repair, and the limits of life. 🧬🚀📸 Bob Goldstein Lab. #ModelMonday

🌳Like a glowing tree in the making ✨ The embryonic mouse kidney is already building an intricate network of tubules 🩵 while interstitial cells 🟡 help shape the surrounding landscape 🔬 📷 Image by Ewa Langner #FluorescenceFriday

❤️✨ Excited to welcome invited speaker Deborah Yelon to #2026SDB in Las Vegas! 🎰 Her lab studies how the vertebrate heart forms and functions, using zebrafish to understand the cellular and genetic mechanisms that drive cardiac development and regeneration. 🐟🫀🔬✨

🧠✨ Excited to welcome invited speaker Helen Willsey to #2026SDB in Las Vegas! 🎰 Her lab studies how autism-associated genes influence embryonic development and contribute to neurodevelopmental disorders and related conditions. 🧬🐸🔬✨

🐟 Nothobranchius furzeri ⏳ The African turquoise killifish lives fast and develops faster! Its embryos can enter diapause, making it a powerful model to study developmental arrest, environmental adaptation and aging 🧬✨ 📸 Image by Alexander Schier lab. #ModelMonday #DevBio

✨ We look forward to hosting Lesley Weaver from Indiana University at the #2026SDB in Las Vegas! 🎰 Her lab studies how inter-organ communication and hormone signaling regulate adult stem cells and maintain tissue homeostasis. 🪰✨ #devbio #drosophila 🪸

✨ We look forward to hosting Alfredo Varela-Echavarria from the Universidad Nacional Autónoma de México at the #2026SDB in Las Vegas! The Varela-Echavarria lab studies the mechanisms of regeneration in garden slugs. 🐌 ✨ #devbio #regeneration 🪸

The sea urchin, Lytechinus variegatus, is a model for development. One urchin produces a ton of gametes and embryos are easy to manipulate in the lab for experiments.🔬 📸 Credit: Kristen Boddy from the University of North Carolina Wilmington #ModelMonday #DevBio 🪸

For this #FluorescenceFriday we have something a bit different. An SEM image of a sterlet sturgeon neurula embryo labelled with SOX9 which decorates the cranial neural crest - a transient embryonic tissue that shapes vertebrate faces. 🔬 #DevelopmentalBiology 📸: Jan Štundl

✨ Looking forward to hearing from Paul Trainor at #2026SDB in Las Vegas! Paul’s work at the Stowers Institute on neural crest development in mammals (sometimes fish and chameleons) has helped bring attention to understudied craniofacial conditions. 🔬 #devbio #Stowers25
