| Outline of Final Research Achievements |
We examined the self-organization mechanism underlying the cellular patterning. When the cells express different combination of nectins and cadherins, heterophilic trans-interaction between nectins preferentially recruits cadherin to heterotypic junctions, and the differential distributions of cadherins between junctions promote cellular intercalations, resulting in the formation of the mosaic pattern. These observations are confirmed by model cell systems, and various cellular patterns are generated by the combinatorial expression of nectins and cadherins. Collectively, the synergistic action of nectins and cadherins generates mosaic pattern, which cannot be achieved by a single mechanism.
