Hepatocytes are the main functional cells of the liver and play a crucial role in various processes such as metabolism, detoxification, and production of proteins. Research in the field of hepatocytes focuses on understanding their structure, function, and regulation in health and disease. This includes studying their role in liver diseases such as hepatitis, cirrhosis, and liver cancer, as well as exploring potential therapeutic strategies targeting hepatocytes for the treatment of liver disorders. Techniques such as cell culture, genetic manipulation, and imaging are commonly used in this research area to investigate the physiology and pathology of hepatocytes.
