Liver development

Liver development begins early in embryogenesis when cells from the developing gut tube form a small outpouching called the hepatic diverticulum. This structure grows into the surrounding mesenchyme, signaling liver cells to differentiate and proliferate. As development progresses, the liver expands, forming structures like blood vessels and bile ducts to support its functions. By the end of fetal development, the liver is a fully functioning organ responsible for blood filtration, nutrient processing, and bile production. This complex process involves coordinated genetic signals and cellular interactions to shape a vital organ essential for survival after birth.
