Fig. 7. Fgfr2cn prostates responded only weakly to androgen
replenishment. (A) Gross tissue appearance of dorsolateral
prostates from Fgfr2cn and control mice 2 weeks after
castration or uncastrated mice at the same age. (B) HE staining of dlp
dissected from the mice 2 weeks after castration (0 day) and at the indicated
days after the androgen replenishment. (C) Sections were immunostained
with anti-PCNA antibodies to reveal the proliferating cells. Inserts:
high-magnification views of the same tissue. (D) The mean percentage of
PCNA-positive cells in regenerating prostates was calculated from three
samples. Data represents means of triplicate samples. CN,
Fgfr2cn mice; F/F, Fgfr2flox
homozygous mice.
