摘要:Interferon-beta (IFN-beta) exhibits a tumor-killing effect; however, injection of IFN-beta alone for lung cancer is often accompanied by side effects. This study investigated the possibility of using umbilical cord mesenchymal stem cells (MSCs) as cellular carriers of IFN-beta.; Isolated umbilical cord MSCs were transfected with a lentivirus packaging IFN-beta-overexpression plasmid. A549 cells were subcutaneously injected into nude mice to establish a non-small cell lung cancer (NSCLC) mouse model. A total of 50 mice were randomly assigned to 5 different groups: a control group, IFN-beta group, IFN-beta-MSCs group, MSCs-lentivirus group, and MSCs group. Next, the IFN-beta-MSCs, MSCs-lentivirus, and MSCs were injected into the A549 lung cancer-bearing mice in the IFN-beta-MSCs, MSCs-lentivirus and MSCs groups, respectively. Mice in the control and IFN-beta groups were injected with solvent or IFN-beta solution. The tumors in nude mice in the IFN-beta and IFN-beta-MSCs groups grew at significantly slower rates than tumors in the control group, and tumors in the MSCs-lentivirus and MSC groups also grew slowly. The rates of tumor cell apoptosis in the IFN-beta and IFN-beta-MSCs groups were significantly higher than those in the MSCs-lentivirus and MSCs groups. The livers, lungs, and kidneys of nude mice in the IFN-beta group displayed hyperemia, exudation, and pathological lesions, while those of nude mice in the IFN-beta-MSCs group showed no abnormal changes. Both INF-beta-MSCs and INF-beta inhibited the growth of subcutaneously implanted lung tumors; however, INF-beta-MSCs specifically targeted the tumor cells, and did not produce the damage to internal organs caused by the use of INF-beta alone.
