Fig. 2From: Chemopreventive effects and anti-tumorigenic mechanisms of Actinidia arguta, known as sarunashi in Japan toward 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK)- induced lung tumorigenesis in a/J mouseNNK-induced pulmonary lesion (group I) in the A/J mouse at 30 weeks of age. Figure 2a, higher magnification of the tumor in Fig. 1a and 1d. Tumor cells with prominent nuclei with mitotic figures (white head) are observed. Figure 2b, high magnification of alveolar area from another portion from the same slide, a wide range of alveolar area shows hyperplasia/atypical adenomatous hyperplasia.
