Fig. 8. Prostate development in Fgfr2^cn and control mice was partially inhibited by neonatal castration. Left panels: gross tissue appearance of prostates from Fgfr2^cn and control mice at the indicated ages with or without neonatal castration. Right panels: the same tissues were micro-dissected to reveal detailed ductal structures. CN, Fgfr2^cn mice; F/F, Fgfr2^flox homozygous mice. Scale bars: 1 mm.
