Abstract: Objective: To investigate the effect of human umbilical cord mesenchymal stem cells (HUC-MSCs) on the invasion and migration of Cal-27 cells in tongue squamous cell carcinoma. Methods: HUC-MSCs conditioned medium was prepared. Cal-27 cells were cultured and the effect of HUC-MSCs secreted factors on Cal-27 cell migration was detected by cell scratch test. The invasiveness and migration of Cal-27 cells before and after co-culture were compared in Transwell cells. Expression levels of genes related to invasion and migration of Cal-27 cells were detected by RT-PCR before and after co-culture. The changes of MMP2 and MMP9 protein expression in tumor invasion and metastasis-related protein molecules were detected by western blot. Results: The migration distance of Cal-27 cells was shorter than that of the control group. After co-culture, the number of invasion and migration of Cal-27 cells decreased. The expression levels of aggression-related genes and proteins were down-regulated. Conclusion: The co-culture of HUC-MSCs and Cal-27 cells can inhibit the invasion and migration of Cal-27 cells.
