Fig. 2From: Emergent material properties of developing epithelial tissuesLinear response of apical strain under cyclic myosin loading. Strain–myosin loops across dorsal closure development, obtained by averaging the apical strain and myosin signals of individual cells over the instantaneous oscillation phase defined by the strain signal. Arrows indicate the direction of the cycle. We note that the loops are hysteretic and become elliptic, indicating a linear viscoelastic relation between strain and myosinBack to article page
