Abstract: The Image-Pro Plus 3.0 morphometric program was used to study the region-specific organization of the human fetal intestine across the radial axis of the gut at weeks 12 and 18 of gestation. The thicknesses of the epithelium, the submucosa, the muscular layers and the myenteric ganglia were measured in resin-embedded semithin sections. Statistical analysis of the collected data was performed by using the two-way ANOVA, the SNK test and the Pearson correlation. The structural changes relating to the gut morphogenesis within this developmental period were followed both light and electron microscopically. The various tissues forming the radial axis of the intestinal tube exhibited different trends concerning their individual development. The thickness of the epithelium did not change in the fetal period investigated, although the epithelial surface displayed characteristic ultrastructural changes. The thickness of the submucosal layer increased significantly, but with different dynamics along the longitudinal axis, whereas the increases in size of the muscular layers and the myenteric ganglia did not differ significantly along the longitudinal axis of the embryonic intestine. The Pearson correlation revealed a significant correlation between the development of the circular muscle layer and that of the myenteric plexus along the whole length of the intestinal tube. The epithelium, the submucosa and the longitudinal muscle layers developed independently between weeks 12 and 18 of gestation.
