"This research gives us hints to looping morphogenesis, how organs form from a single tube to the rotating structure of intestines," said Natasza Kurpios, assistant professor of Molecular Medicine at the College of Veterinary Medicine at Cornell. Kurpios co-authored the study, "On the growth and form of the gut" in the current issue of Nature. Her co-authors are Thierry Savin, Amy E. Shyer, Patricial Florescu, Haiyi Liang, L. Mahadevan and Clifford J. Tabin, all of Harvard Medical School and Harvard University.
Kurpios and her co-authors developed a model that mimics how developing intestines in vertebrates form the characteristic looped pattern in the body cavity. That model not only provides a template for organ asymmetry; it also could lead to better diagnosis of veterinary and human maladies such as malrotation of the intestines in babies and gastric torsion in large-breed dogs such as Labrador retrievers. "By understanding the patterns of loops, we could better identify and more accurately diagnose these conditions," Kurpios said. "This also gives us hints to the formation of other organs, such as the heart and the vascular system."
