Figure 1

Immunohistochemical staining for HIF-2α, TWIST, and CXCR4. Columns correspond to immunostaining for HIF-2α, TWIST, and CXCR4, respectively. The first row exhibits weak staining of nodular hyperplasia tissues with the indicated antibody ((a)–(c)); the succeeding rows show moderate staining ((d)–(f)) and strong staining ((g)–(i)) of HIF-2α, TWIST, and CXCR4 in PTCs. All the pictures are in high-power fields (×400).
