UC Santa Barbara

(A) Embryonic tissues elongate via convergent extension, where cell polarization directs active stresses, driving rearrangements (T1 transitions). (B) Fluctuating stresses fluidize tissues, enabling morphogenesis. (C) Key cell processes—force production, polarization, and adhesion—are modeled in robotic units: actomyosin as motorized gears, chemoreceptors as photodiodes, and cadherins as rolling magnets. Polarity conventions differ from biology. (D) Photos of two robotic units (top and isometric views), showing gear rotation and applied forces. Scale bar: 5 cm.
