The digestive tract exhibits region-specific morphology and cytodifferentiation along the anteroposterior axis. We analyzed the spatial expression patterns of Hox genes belonging to the HoxA and HoxB cluster (Hoxa-4∼a-9, Hoxb-5∼b-9) in the developing chick digestive tract. The expression domains of these Hox genes correlated with morphological subdivision of the digestive tract along the anteroposterior axis. Copyright © 2001 Elsevier Science Ireland Ltd.
