Results from computational model for folding of inner splanchnopleure (iSPL). Top row: Ventral view of the model at stages HH5-10, divided into three phases. Phase 1: differential growth between SPL layers; Phase 2: contraction along anterior intestinal portal (AIP, green); Phase 3: growth of heart field (HF, red). Middle row: Cross-sections from the model at locations indicated by the dashed black lines. Bottom row: Schematics of the same cross-sections [based on drawings from Kirby (2007)]. Although there are some morphological differences, the model captures the evolving shapes of the foregut (FG) and heart tube (HT) reasonably well.
