Fig. 6. Expression of the androgen receptor in Fgfr2^cn prostates. Prostates were harvested from 6-week-old mice before (0 day) and at the indicated days after the castration. Expression and cellular localization of the AR were assessed with immunostaining with anti-AR antibodies. Notice that a considerable amount of AR in Fgfr2^cn prostates remained in the nuclei at day 14 after the castration. ap, anterior prostate; dp, dorsal prostate; lp, lateral prostate; vp, ventral prostate; F/F, homozygous Fgfr2^flox mice; CN, Fgfr2^cn mice.
