Development of the gastrointestinal tract is a complex process that uses unique mechanisms and depends heavily on transcriptional activation. Here we discuss the regionalization of the primitive gut and formation of the intestine and liver. Anterior-posterior positioning in the primitive gut is important for establishing regions that will become functional organs. Coordination of transcription factors and signaling factors between the epithelium and mesenchyme is required for intestinal development and homeostasis. Liver development utilizes a complex transcriptional network that is required for organ domain establishment, cell differentiation, and adult function. Discussion of these transcriptional mechanisms gives us insight on how the primitive gut, composed of simple endodermal cells, develops into multiple diverse cell types that are organized into very complex functional mature organs.
