Abstract: Objective: To study the proliferation and migration of oral tongue squamous cell carcinoma HSC-4 cells induced by DVDMS-PDT. Methods: To detect the cytotoxicity of DVDMS and the uptake of drugs by cells, the cells were divided into control group and DVDMS-PDT treatment group with different concentrations (0.1, 0.5, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, and 8.0 mg/L, respectively). The laser energy density were 0.75, 1.50, 3.00, 6.00J/cm2. The effects of different drug concentrations and light energy density on cell viability were analyzed by CCK-8. Scratch assay and Transwell experiment were used to observe the changes of cell migration ability. Results: DVDMS toxicity experiments showed that the single drug had less cytotoxicity, and combined with laser irradiation, it could significantly inhibit the proliferation of HSC-4 cells (P<0.05). Compared with the control group, the healing rate of scratch assay was decreased,and the number of transwell penetrated cells was decreased (P<0.05). DVDMS concentration at 2.0 mg/L, 6 hours incubation, and light energy density above 3.00J/cm2 could effectively kill HSC-4 cells. Conclusion: DVDMS-PDT can effectively kill the tongue squamous cell carcinoma cell line and inhibit the migration of HSC-4 cells. Photosensitizer concentration, incubation time, and light energy density are important factors affecting the therapeutic effect.
