Abstract

Recent evidences suggested that Mesenchymal stem cells (MSCs) may be involved in tumor formation by modulating of the tumor microenvironment, but it is still unclear the potential of MSCs in the malignant transformation of oral mucosa. Using a chemically-induced oral carcinogenesis model by 4-nitroquinoline-1-oxide (4NQO), we generated precancerous lesions and cancerous lesions in the oral cavity of rats. Flow cytometric analysis on lesions derived single cell suspension revealed an increase in the proportion of MSCs and a decreased proportion of T cell during oral mucosa malignancy. Moreover, MSCs showed increased immunosuppression capacity on T cell proliferation during mucosa malignancy. At last, we demonstrated that higher frequency of lesions resident MSCs was correlated with more Ki67 expression in the lesion, which indicated higher cellular proliferative status in the lesions. Our study demonstrated that MSCs may play an important role in oral mucosa malignant transformation through regulating T cell proliferation.
