} | Liver stem cells, also known as oval cells, are primarily located in the **periportal regions** of the liver, particularly near the **canals of Hering**. These cells are found within the **periportal area**, which is the region surrounding the portal tracts that contain the portal vein, hepatic artery, and bile ducts.
