The zoo of the gene networks capable of pattern formation by extracellular signaling

The Takeaway
We used to think the way cells organize into complex patterns was as chaotic and diverse as life itself. It turns out that despite the millions of ways genes could interact, researchers mathematically proved there are only three fundamental classes of networks capable of creating a biological pattern. This means nature isn't just winging it; it’s following a strict set of universal mathematical rules. By understanding these three classes, we could eventually learn to grow complex tissues or even organs to order. It’s like finding out every building on Earth is actually based on just three simple blueprints. This discovery brings us one step closer to truly 'programming' biological life.
From the abstract
A fundamental question of developmental biology is pattern formation, or how cells with specific gene expression end up in specific locations in the body to form tissues, organs and, overall, functional anatomy. Pattern formation involves communication through extracellular signals and complex intracellular gene networks integrating these signals to determine cell responses (e.g., further signaling, cell division, cell differentiation, etc.). In this article we address two question: 1) Are there
