From Embryology
Human Embryonic Liver Development
Week
Carnegie Stage
Feature
Week 4

Carnegie stage 11
hepatic diverticulum development (ductal plate)
Carnegie stage 12
cell differentiation

septum transversum forming liver stroma

hepatic diverticulum forming hepatic trabeculae

Carnegie stage 13
epithelial cord proliferation enmeshing stromal capillaries
Week 5
Carnegie stage 14
hepatic gland and its vascular channels enlarge

hematopoietic function appeared

Week 7
Carnegie stage 18
obturation due to epithelial proliferation

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

Week 7 to 8
Carnegie stage 18 to Carnegie stage 23
biliary ductules developed in periportal connective tissue

produces ductal plates that receive biliary capillaries
