ABSTRACT
Objectives of this study were to establish a leukemia mouse model in the Balb/c mouse based upon the A20 cell line (murine B-lymphoma/leukemia cell line, H-2d). Here we demonstrate for the first time that A20 cells were infiltrated into tissue and bone marrow, thereby evaluate the feasibility of using A20 leukemic cells as a leukemia model. In the study, changes of behavior, survival rate and histological changes of major organs after intravenous injection of A20 cells (1x105, 1x106 or 1x107) into Balb/c mice were observed. After inoculation of 1x106 cells, animals survived up to 38.3 days, although there were no significant correlation between the number of injected cells and life-span. At 21 and 28 days post-injection, both hematoxylin-eosin and CD45R immunohistochemical stains showed diffuse large B-cell lymphoma in the liver. FACS analysis was performed after injection of fluorescent nanomaterial (MNPs@SiO2 RITC)-labeled A20 cells. The labeled A20 cells were detected in bone marrow from 6 hours post-inoculation, indicative of the cellular infiltration. This is the first study that demonstrated the invasion of A20 cells into the bone marrow of Balb/c model using A20 cells. With the occurrence of systemic lesions following metastasis of the cells into lymph nodes and neighboring tissues via bone marrow infiltration, it is suggested that the A20 cell-inoculated Balb/c miouse could be an animal model of acute lymphocytic leukemia.
