🎄 Day 11 of the 24 Days of Development ✨🪸 Retinoic acid (RA) signalling is important in early heart development🫀🐟 The authors showed that inhibiting RA in embryos results in smaller ventricles, reduced smooth muscle and abnormal ventral aorta! https://t.co/SxPh0i3K5R

🎄 Day 10 of the 24 Days of Development ✨🪸 In developing zebrafish, the growth factors Mdka and Mdkb, act through the receptor Ptprz1b 🐟 This study reveals a novel mechanism where this trio coordinates neural plate circuit development 🧠🔬 https://t.co/CzSq1hDyEO

🎄 Day 9 of the 24 Days of Development ✨🪸 In Drosophila Robo3 guides axons independently of the canonical repellent, Slit. The authors' findings challenge current models moving the field deeper into understanding the nervous system development!  🪰🌟 https://t.co/IcXtZbyaWN

President Trump says it perfectly. A patchwork of 50 different state systems creates a maze of conflicting regulations, resulting in chaos. Follow me to join the conversation on leading the AI revolution.

🎄 Day 8 of the 24 Days of Development ✨🐟 The lower urinary tract may look simple… but its development is basically a molecular turf war between the bladder and the urethra 🧬💥 https://t.co/SbMjpy4KFF

🎄 Day 7 of the 24 Days of Development ✨🐟 Bone development usually follows a nice, orderly schedule… unless someone hits the fast-forward button. 🦴⏩ The result? Premature ossification, chunky bones and shortened skeletal elements 💀✨ https://t.co/qE5TQSnrVa

🎄 Day 6 of the 24 Days of Development ✨🐟 Intestinal villi don’t just grow, they engineer themselves 🏗️ through a careful balance of mechanical forces and tissue interactions ☯️ When that balance is off… things get interesting🔬🌟 https://t.co/cyR0vG7XB9
