This study on Zebrafish liver development. Liver is one of the major interior organs in the body and its eminence for the metabolism, purification and homeostasis has been well recognized. In this analysis, I concise current growths in studying the liver initiation and growth through embryogenesis by zebrafish as the model system. We mostly focused on the topics connected to the requirement of hepatoblasts from the endoderm, the creation and development of the liver bud, the variation of hepatocytes and the bile duct cells from the hepatoblasts, and lastly the role of mesodermal indications in directing liver expansion in zebrafish.
