RESUMEN

Objective: To establish the transgenic mice-derived allografts (MDAs) so as to provide an appropriate experiment model of pancreatic cancer. Methods: By using the tissue fragments derived from transgenic mice with pancreatic cancer named LSL-KrasG12D/+; Trp53fl/+; Pdx1-Cre (KPC) mice and subcutaneous transplant technique, we constructed the MDAs. We evaluated the histopathological characteristics of MDAs and infiltration of immune cells by H&E staining, Masson's staining and immunohistochemical method. Results: MDAs could mimic the pathological morphology, proliferation and fibrosis of pancreatic cancer precisely. Besides, the infiltration of immune cells in MDAs tumor was the same as that of pancreatic cancer. Conclusion: MDAs are an effective model to mimic the development of pancreatic cancer.
