Figure 2

Growth pattern of WT and Tg(K6b-E6/E7) cervix during the estrous cycle. Ki67 determination (a) and 2-h BrdU incorporation (b) during the growth phases in transformation zone, and inner and outer cervix showed that oncogenes added suprabasal proliferating cells to those regularly present in the basal layer. Note the basal to suprabasal K5 distribution gradient, particularly evident in the outer cervix. Some basal (b), parabasal (p) and suprabasal (s) cells are indicated. (c) A histological comparison between WT and Tg(K6b-E6/E7) cervix of 9-week-old mice showed similar tissue appearance at each estrous cycle phase but a thicker epithelium during the growing phases in the latter than in the former, in some cases evidenced as epithelia invading the stroma (arrows). Scale bar, 100 μm.
