From: Repeated exposure of the oral mucosa over 12 months with cold plasma is not carcinogenic in mice
Representative histological analysis of squamous cell carcinoma (SCC) formation in the mucosa. Haematoxylin–eosin staining of squamous cell carcinoma (SCC) of the oral mucosa of mice [(A, B): MWM + high dose dibenzo(a)pyrene (DBP); (C, D) ultraviolet (UV) 48 s + high dose DBP; (E, F): kINPen 10 s + high dose DBP]. SCCs showed an endophytic and plump invasive growth pattern with mostly mild to moderate atypia.
