Figure 1. Schematic of intestinal changes in X.laevis during metamorphosis. The larval (tadpole) intestine is comprised of a single layer of fully differentiated epithelial
cells (55,56). There is a single fold in the intestine called the typhlosole. During metamorphosis extensive remodeling occurs to create the adult frog intestine (9,10).
The first stage of this process is the death of larval epithelial cells followed by adult epithelial cell proliferation and differentiation. In addition, there is an increase
in the connective and muscle tissue. By the end of metamorphosis, the adult frog intestine consists of multiple epithelial folds, highly resembling the intestines of other
vertebrates. bb, brush border of EP. EP, epithelial cells; CT, connective tissue. Image published in: Stolow MA and Shi YB (1995) Copyright © 1995.
