Determination of the effect of IFN-γ injection on the tumor via tail-vein to validate the IFN-γ released from the wound model. A.) The tumor growth curves showing the double-phase in the IFN-γ injection group, the inhibition phase, and the inhibition missing phase. In the inhibition missing phase, the level of TGF-β increased significantly in the IFN-γ injection group as compared to that in the control (marked by *, p < 0.05). B.) The activity of MMP-2 and MMP-9 as detected by the gelatin zymography analysis showing the decrease in the inhibition phase of the IFN-γ injection group and the significant increase in the inhibition missing phase as compared to the control group (marked by *, p < 0.05).
