An outstanding question in embryo development is how spatial patterns are formed robustly. In the zebrafish spinal cord, neural progenitors form stereotypic patterns despite noisy morphogen signaling and large-scale cellular rearrangements during morphogenesis. By directly measuring adhesion forces and preferences of three types of endogenous neural progenitors, we provided a direct proof of the differential adhesion model, mediated by differential cadherin expression, assisting tissue patterning in vivo. The unique combinatorial expression of N-cadherin, Cadherin 11, and Protocadherin 19 in each cell type ensures homotypic preference ex vivo and patterning robustness in vivo. The cell fate and adhesion codes are regulated by the Sonic hedgehog gradient. We propose that robust patterning during tissue morphogenesis results from a previously unappreciated interplay between morphogen gradient and adhesion-based self-organization. Pattern formation in the neural tube results from cellular self-organization based on a combinatorial adhesion code instructed by the morphogen Sonic hedgehog.
