His work showed that certain cells can direct the fate of other cells—an idea that changed developmental biology forever. 👉 Read more on Britannica.com

💡 Impact today:

It laid the foundation for developmental biology, explaining how complex organisms form from a single fertilized egg. It inspired regenerative medicine and stem cell research 🌱, where cells can be guided to become specific tissues.

📌 His discovery: organizer cells in the embryo can create a second body axis and form complete structures—a key concept for understanding how life is built. (nobelprize.org). 

From embryos to modern medicine: ideas that continue to move science forward. 🔬✨
