Carnegie Stage
Feature
Week 4

11
hepatic diverticulum development (ductal plate)
12
cell differentiation

septum transversum forming liver stroma

hepatic diverticulum forming hepatic trabeculae

13
epithelial cord proliferation enmeshing stromal capillaries
Week 5

14
hepatic gland and its vascular channels enlarge

hematopoietic function appeared

Week 7

18
obturation due to epithelial proliferation

bile ducts became reorganized (continuity between liver cells and gut)

Week 7-8

18 to 23
biliary ductules developed in periportal connective tissue

produces ductal plates that receive biliary capillaries
