Outline of Final Research Achievements

Measurement of biophysical parameters of living tissues such as rigidity often requires exogenous manipulation on the tissues, but such a manipulation perturbs spontaneous morphological processes undesirably. Here, we developed a non-invasive statistical method to estimate biophysical parameters. Our strategy is to model the tissue as a continuum mechanical system, and to use time-lapse imaging data of tissue dynamics in order to compute the maximum likelihood estimates of model parameters. We validated our method on epithelial spreading of Madin-Darby canine kidney cells, a well-known model system for collective migration.
