WebCrypt formation originates within the basal part of the villi as new luminal structures form and extend into the underlying mesenchyma and eventually fuse with the intestinal lumen by an upward migration. Initially, cell proliferation occurs along most of the luminal epithelium, but once villi form it is restricted to the intervillus spaces.
