Description
During gastrulation, an early stage of embryonic development, cell migration is crucial for the formation of germ layers that eventually develop into tissues and organs. We develop a continuum mechanical model of dual layer cell migration during gastrulation that includes intercalation of cells between the mesenchymal and epithelial cell layers. Approximate Bayesian computation with sequential Monte Carlo (ABC-SMC) and sensitivity analysis are used to obtain parameter estimates and to compare between various model formulations. A goal of this work is to determine the functional form of intercalation and cell layer growth that best reflects the experimental data from spreading aquatic frog Xenopus laevis tissue.
