tert?/? tissues increase melanoma invasiveness and progression. (A) Hematoxylin and eosin (H and E) images of melanoma arising in a WT (Upper) or tert?/? recipient fish. Strong infiltration into other tissues was typical in tert?/? fish but not in WT (arrowheads). (B) Melanomas were staged according to histopathology into benign lesions (melanosis), noninvasive and invasive malignant tumors (P = 0.0269; WT n = 9; tert?/? n = 10). (C) Analysis of malignant tumors for cellular atypia (P = 0.0278; WT n = 5; tert?/? n = 7). (D) Representative immunofluorescence images of PCNA-positive cells (red) in melanoma (green) developed in WT chimeras and in tert?/? chimeras. Dashed lines locate the skin (no green fluorescence), squares show the place of amplification, and arrows indicate PCNA-positive cells. (E) Quantification of PCNA-positive melanoma cells in WT and tert?/? chimeras. Data are represented as mean � SEM. *P < 0.05; n = 3.
