BDNF expression in bronchial and alveolar epithelium, SCC and ADC tissues by immunohistochemical staining. Hematoxylin was counterstained for nuclei. Weak expression of BDNF was shown in bronchial epithelial cells (a), and no expression was found in alveolar epithelium (d). SCC showed positive expression of BDNF (b and c), including the moderate staining of T1 stage (B), and intense staining of T3 stage (c). ADC showed positive expression of BDNF (e and f), including the moderate staining of T1 stage (e), and intense staining of T3 stage (f). (magnification, 400×)
