Introduction

This section of notes gives an overview of how the stomach and duodenum develops. The GIT is best imagined as a simple tube, the upper part being the foregut diverticulum, which is further divided into oesophagus and stomach.

During week 4 at the level where the stomach will form the tube begins to dilate, forming an enlarged lumen. The dorsal border grows more rapidly than ventral, which establishes the greater curvature of the stomach. A second rotation (of 90 degrees) occurs on the longitudinal axis establishing the adult orientation of the stomach.

Some Recent Findings

  • FGF4 and retinoic acid direct differentiation of hESCs into PDX1-expressing foregut endoderm in a time- and concentration-dependent manner.[1] "Retinoic acid (RA) and fibroblast growth factor 4 (FGF4) signaling control endoderm patterning and pancreas induction/expansion.'
  • FGF10 is required for cell proliferation and gland formation in the stomach epithelium of the chicken embryo. [2] "The development of digestive organs in vertebrates involves active epithelial-mesenchymal interactions. In the chicken proventriculus (glandular stomach), the morphogenesis and cytodifferentiation of the epithelium are controlled by the inductive signaling factors that are secreted from the underlying mesenchyme. ... FGF10 signaling, mediated by FGFR1b and/or FGFR2b, is required for proliferation and gland formation in the epithelium in the developing chick embryo."

Stomach Mesentery

In the second trimester, the ventral and dorsal mesenteries associated with the stomach are still anatomically different from the newborn. The figure shows a lateral view of this process comparing the early second trimester arrangement with the newborn structure.

Ventral Mesogastrium

Attached to the superior end of the stomach will form the lesser omentum. This structure will connect the lesser curvature of the stomach to the liver as a ligamentous structure.

Dorsal Mesogastrium

Attached to the inferior end of the stomach initially as an extended fold, this later fuses as a single "apron-like" structure, the greater omentum. Fusion will also incorporate the transverse colon part of the large intestine. This will also contribute the gastrosplenic ligament (gastrolienal ligament).

Greater-omentum.jpg The greater omentum hangs like an apron over the small intestine and transverse colon. It begins attacted to the inferior end of the stomach as a fold of the dorsal mesogastrium which later fuses to form the structure we recognise anatomically. The figure below shows a lateral view of this process comparing the early second trimester arrangement with the newborn structure.

Duodenum/Pancreas Rotation

Pancreas rotation cartoon After the stomach the initial portion of the gastrointestinal tract tube is the duodenum which initially lies in the midline within the peritoneal cavity.

This region, along with the attached pancreas, undergoes rotation to become a retroperitoneal structure.

This diagram shows the rotation with spinal cord at the top, vertebral body then dorsal aorta then pertioneal wall and cavity.

Stomach Hormonal Development

The gastrointestinal tract has its own complex entero-endocrine system (enterohormones) that regulates many regional tract functions.

Cells within the stomach express a range of peptide hormones known to regulate a range of gastric functions including secretion of digestive enzymes, mucous and the movement of the luminal contents. The list below shows the earliest detectible presence of specific hormone-containing cells in regions of the developing human stomach.

Hormonal Timecourse

8 weeks - Gastrin containing cells in stomach antrum. Somatostatin cells in both the antrum and the fundus.

10 weeks - Glucagon containing cells in stomach fundus.

11 weeks - Serotonin containing cells in both the antrum and the fundus.

Expression data based upon[4]

Other Gut Peptides

  • Cholecystokinin (CCK), pancreatic polypeptide, peptide YY, glucagon-like peptide-1 (GLP-1), oxyntomodulin (increase satiety and decrease food intake) and ghrelin

Mouse

The images below show differential gene expression of some selected markers during development (E10.5 and E13.5) of the mouse gastrointestinal tract.[5]
