Abstract

The aim of this study was to investigate and describe basic features of Pan_02 murine pancreatic ade- nocarcinoma tumor model. Pan_02 has very low sensitivity to chemotherapeutics therefore it is very similar to human pancreatic cancers. Mice were subcutaneously injected with different number of cells and tumor growth was measured. Tumors were also investigated with ultrasonograph VEVO2100 in doppler mode to detect viable and function- al blood vessels. Collected tumor samples were investigated to asses necrosis and blood vessel permeability. We found substantial differences in tumor growth depending on a number of inoculated tumor cells. Mice injected with 0.5 × 106 cells gave the most consistent pattern of growth. All tumors showed substantial vascularisation but bigger tumors were more likely to develop larger blood vessels instead of a more dense network. Murine Pan_02 cancer model shares many features with human PDAC cancers and therefore it is a good model to study new drugs. Injection of 0.5 × 106 cells gives consistent results although it requires more time for the tumor to grow. It also allows the immune system to adapt. Owing ta good vascularisation, Pan_02 is a good model to study chemotherapy against pancreatic aden...Continue Reading

Bartonellosis

Bartonellosis is an infection caused by bacteria in the genus Bartonella and can present as a variety of diseases depending on the organism involved. While asymptomatic infection has been reported, immunocompromised individuals are more susceptible to severe infection. Find the latest research on bartonellosis here.
