It has been observed that NSCLC adenocarcinoma is a more mesenchymal-like tumor type, since it has been observed that vimentin, a marker of mesenchymal cells, was overexpressed in well differentiated adenocarcinomas and in the H23, A-549 and HCC-44 cell lines, but not detected in SCC tissues [21], [22]. Here, VIM is linked to adenocarcinoma.
