Fig. 1: Immunohistochemical staining of pS6 ribosomal protein in pleural mesothelioma (PM).

A Hematoxylin and eosin stained TMA punches of epithelioid PM and corresponding immunohistochemical pS6 ribosomal protein staining. The immunohistochemical staining intensity reaching from 1 (weak), 2 (moderate) to 3 (strong). B Hematoxylin and eosin stained TMA punches of sarcomatoid PM and corresponding immunohistochemical pS6 ribosomal protein staining. TMA tissue micro array, PM pleural mesothelioma. Scale bar 200 µm.
