Summary: Morphogenesis is a spatially and temporally regulated process involved in various physiological and pathological transformations. However, the driving force of morphogenesis initiation remains elusive. Here, it is shown that morphogenesis can be tuned by manipulating tissue fluidity, cell adhesion forces, and mechanical properties to influence the progression of compression gradient. Together, the dynamics of compression gradient arising from interfacial mechanical interaction provide a conserved mechanism underlying morphogenesis initiation and size control during tissue growth. HoloMonitor M4 was used for cell morphology changes including cell area, cell thickness, cell sheet area, and cell sheet thickness
