One mouse with remission showed shrinkage in the palpable tumor after necropsy, and pan-cytokeratin (reactivity with 1, 2, 5, 6, 7, 8, 10, 11, 14,17, 18 and 19 cytokeratins) and vimentin IHC staining verified the presence of carcinoma, which was under the control of the immune system. Here, VIM is linked to neoplasm.
