Morris Hepatoma is a type of liver cancer that was named after the American cancer researcher, J.B. Morris. The spelling of "Hepatoma" is pronounced /hɛpəˈtoʊmə/ according to the International Phonetic Alphabet (IPA), which represents the sounds of spoken language. The "hepa-" in the word refers to the liver (hepat/o), while "-toma" refers to a tumor composed of tissues derived from embryonic mesodermal germ layer. Accurate spelling and pronunciation of medical terms like Morris Hepatoma are essential for clear communication among healthcare professionals and patients.
Morris Hepatoma, also known as the Morris Hepatoma 7777, is a specific type of cancerous tumor developed in the liver of rodents. It was first discovered and extensively studied by Dr. Joseph Charles Morris, an American scientist, in the 1950s. This particular hepatoma model, derived from a strain of male Fischer 344 rats, has since been widely used in cancer research and is considered a valuable tool in studying liver cancer and its underlying mechanisms.
Morris Hepatoma is characterized by the excessive growth and proliferation of hepatocytes, the primary cells of the liver. The tumor is typically malignant and can exhibit invasive behavior, meaning it has the potential to infiltrate surrounding tissues or metastasize to distant parts of the body. Researchers utilize this model to investigate various aspects of liver cancer, including tumor development, progression, and response to treatments.
The Morris Hepatoma 7777 has been extensively studied due to its ability to reproduce many of the characteristics observed in human liver cancer, making it a valuable model for preclinical research. It has been used to study the mechanisms of tumorigenesis, explore potential therapeutic agents, and evaluate different treatment strategies in order to improve overall understanding and management of liver cancer.
Overall, Morris Hepatoma serves as an essential tool in liver cancer research and has significantly contributed to advancements in our knowledge and treatment options for this particular type of cancer.
