The authors regret that the published version of this article contained error in Figure 7. In both Figure 1D and Figure 7B, Kaplan-Meier estimate was used to analyses survival rates of OSCC patients. The Kaplan-Meier survival curve in Figure 7B was inadvertently presented with the same image as Figure 1D. We have accordingly corrected and replaced the image in Figure 7B. This change does not affect the interpretation of Figure 7. The corrected Figure 7 is given below. The error has no influence the conclusions of the work.
Figure 7.
Overexpression of podoplanin and MT1-MMP in OSCC tissues is related to shorter survival. A. Representative photographs of immunostaining for podoplanin and MT1-MMP in normal epithelium, dysplasia epithelium, microinvasive OSCC, primary OSCC and nodal metastasis. Small and large black frames indicate the original and the magnified areas, respectively. Scar bar =100 μm. B. The Kaplan-Meier estimate of 5-year survival rate in 73 OSCC patients according to podoplanin and MT1-MMP expression.
