Statistical values of the comparison of WNT4 gene expression in thymic epithelial tumors (TETs), including thymomas and thymic carcinomas, with normal childhood thymuses (A, n = 6) and normal adults thymuses (B, n = 15) as represented in Figure 1 (two-tailed Student’s t-test was applied for statistical analysis). Here, WNT4 is linked to thymoma.
