Fig. 4From: The growth inhibitory effect of human gingiva-derived mesenchymal stromal cells expressing interferon-β on tongue squamous cell carcinoma cells and xenograft modelGMSCs/IFN-β promoted the apoptosis of CAL27 cells in vitro. Flow cytometry analysis showed that GMSCs/IFN-β significantly promoted cell apoptosis compared with the DMEM, GMSCs or GMSCs/vector group. All data are shown as mean ± SD. *P < 0.01 versus the DMEM group, #P < 0.01 versus the GMSCs/vector groupBack to article page
