[Establishment of A20 Murine B Lymphoma Transplantation Model Labeled with Luciferase].

Abstract

OBJECTIVE:

To establish the animal model of luciferase-transfected A20 murine B cell lymphoma, so as to provide experimental tools to explore the effect of graft versus tumor.

METHODS:

Luciferase- labeled A20 cells were cloned with puromycin selection. Transfected A20 cells and C57BL/6 bone marrow were inoculated into the irradiated BALB/c mice by injection in tailvein to establish the transplantation model. The bioluminescent imaging technique was used to monitor the tumor growth, and then the survival, body weight, tumor formation and pathological characteristics of target organs were observed.

RESULTS:

A20 cell line stably expressing luciferase gene was successfully obtained. The the bioluminicent imaging found that the tumor luminescence could be observed on day 8 of A20 cell inoculation, and the mean fluorescent intensity was increased along with the tumor growth. Compared with the BMT group, the survival rate and body weight of BMT+A20-Luc+ mice were decreased significantly. General anatomy showed the tumor mainly formed in the liver and spleen.

CONCLUSION:

A mouse transplantation model with luciferase- transfected A20 cells has been successfully established, thus laying a foundation for investigation of graft-versus-tumor.
