<p>A. Negative staining in normal bronchial epithelium in non-cancerous lung tissue. B. Negative staining in normal pneumocytes in the alveoli of non-cancerous lung tissue. C. TRIM24 immunostaining was negative in bronchial epithelium adjacent to lung adenocarcinoma. D. Negative TRIM24 staining in a case of Stagel, moderately differentiated squamous cell carcinoma. E. Negative staining in Stagel, well differentiated lung adenocarcinoma. F. Positive TRIM24 staining in a case of Stage II, poorly differentiated squamous cell carcinoma. G. Positive TRIM24 staining in a case of Stage III, moderately differentiated adenocarcinoma. H. Negative control using rabbit immunoglobulin.
