Abstract

Cardiac looping is a vital morphogenetic process that transforms the initially straight heart tube into a curved tube normally directed toward the right side of the embryo. A finite element (FE) model for the initial phase of looping was constructed to investigate possible mechanisms responsible for looping. The model includes realistic material properties, actin orientations, and geometry for the stage 10 chick heart (33hrs of 21 day incubation period). The model is used to select the correct distribution of morphogenetic forces (e.g. growth, cytoskeletal contraction, actin polymerization) responsible for the initial phase of c-looping. This is done by matching (1) experimental and model-predicted global shape changes and (2) experimental and model-predicted local morphogenetic stresses and strains.
