Enzyme-histochemistry of the foreskin microvasculature using fructose-1,6-diphosphatase

Microvascular capillaries (blood and lymph) in human foreskin were examined for staining characteristics for fructose-1,6-diphosphatase (FDPase). Based on enzyme-histochemistry and electron microscopy, both blood and lymph vessels and microvessels as well as dermal smooth muscle all stain positively but with varying intensity for FDPase.
