EMT and GREM1 expression are induced in CC tissues. a Immunohistochemical staining of GREM1, E-cadherin, N-cadherin and Vimentin in the adjacent and CC tissues (scale bar = 100 um; black square is CC tissue, and yellow square is adjacent tissue); b positive rate of GREM1, E-cadherin, N-cadherin and Vimentin in the adjacent and CC tissues; the protein expression = positive cells/total cells × 100%, the experimental data were expressed as percentage and analyzed by χ² test; n = 109; *p < 0.05 vs. the adjacent tissues.
