Abstract

The invention provides an animal model constructing method for studying epithelial and stromal hyalinosis of hepatocellular carcinoma. The method is characterized by the following steps: inoculating cancer cells to liver of an experimental animal in situ under guidance of ultrasonic equipment; and dynamically observing related index changes and lung metastasis conditions of epithelial and stromal hyalinosis. The method has the advantages that: the manufacturing process is simple and easy, has high success rate, and can be widely popularized and applied; and the manufactured animal mode can truly simulate the pathological process of clinical metastasis of hepatic carcinoma, and can dynamically reflect the developing process of the epithelial and stromal hyalinosis of the hepatic carcinoma.

Description

Technical field [0001] The present invention relates to constructing an animal model for studying the dynamic process of hepatocellular carcinoma epithelial mesenchymal transformation. The present invention can also become an ideal verification platform for the development of targeted anti-tumor drugs for the hepatocellular carcinoma epithelial mesenchymal transformation process. Background technique [0002] Primary liver cancer is one of the highly malignant tumors, and its mortality rate ranks second among malignant tumors in my country. Most deaths of liver cancer patients are related to liver cancer recurrence and metastasis. Studies have shown that the recurrence and metastasis of liver cancer is a complex process involving multiple genes and multiple steps, including tumor cell adhesion, migration, and tumor cell degradation of extracellular matrix. At present, the molecular mechanism of its occurrence is not fully understood. Further research The molecular mechanism of li...
