This section of notes gives an overview of gall bladder and hillary tree development, histology and abnormalities associated with the biliary system. In the adult, the gall bladder is a site of bile salt storage and concentration, to then be released into the duodenum where they act to solubilize dietary lipids by their detergent effect. Bile salts are a cholesterol derivative (breakdown product).
The transverse septum differentiates to form the hepatic diverticulum and the hepatic primordium, these two structures together will go on to form different components of the mature liver and gall bladder.
The hepatic diverticulum divides into two parts: pars hepatica (larger cranial part, primordium of the liver) and pars cystica (smaller ventral invagination, primordium of gall bladder).
The pars cystica vacuolates and expands, the stalk becoming the cystic duct. This structure is initially hollow, then solid (by proliferation of epithelial lining), and then recanalized occurs by vacuolation of this expanded epithelium. There are several opinions as to whether the duct has a solid phase or remains patent throughout development.

Gall-bladder Human Embryo (CRL)
- 7.5 mm - epithelium is surrounded by a layer of mesenchyma, and the entire structure is so imbedded in the under surface of the liver that it causes only a slight swelling of the peritoneal surface. Above and on the sides the mesenchyma is in direct relation with the hepatic trabecular, and it receives a few prolongations of the venous capillaries. Below it is covered by the peritoneal epithelium except on the left, where that layer is reflected to the abdominal walls in connection with the falciform ligament. In later stages the gall-bladder is separated from the hepatic trabecular on either side, and is attached to the liver only along its upper surface.
- 16 mm mesenchyma surrounding the gall-bladder is still undifferentiated.
- 22.8 mm forms two broad concentric zones, of which the inner is darker and more compact than the outer.
- 29 mm certain cells in the peripheral part of the dark zone form a third layer, which is thin and somewhat interrupted. As seen in later stages these cells are myoblasts, so that at 29 mm all three layers of the adult gall-bladder are indicated. These are the mucosa, muscularis, and serosa. The layers become gradually less distinct toward the hepatic duct.
These mainly relate to postnatal infections. Recent studies in the mouse have identified that gastrointestinal tract listeria infections can relocate to the gall bladder and reside there, leading to later reinfection of the gastrointestinal tract.
