Figure 5: Levels of TGFβ and IL23 produced by premalignant oral lesion cells and HSNCC. Cells from enzymatically dissociated normal tongue epithelium, premalignant oral lesions and HSNCC were cultured for 36 hours. Levels of active TGFβ and IL23 in the conditioned media were then measured. **p<0.01. |
