(A) Section of human fetal prostate at 14 weeks of gestation. The red dots indicate the proximal origin of a prostatic duct and the first branch point, respectively. The distance between these two points is ~250µm. (B) A thick (0.5mm) coronal section of a 17-week human fetal prostate photographed with transmitted light. Red dots are placed on 3 prostatic ducts depicting ductal length to the first branch point. In all three cases the distance is ~1000μιm. The thin white line above the scale bar in (B) is ~1000μιm.
