Enzyme-histochemical staining of dermal lymphatic capillaries by guanylate cyclase.
Human foreskins were examined for enzyme-histochemical staining of microvessels using guanylate cyclase, an enzyme similar to adenylate cyclase. Like 5'-nucleotidase (which hydrolyzes 5'-adenosine monophosphate to adenosine), and adenylate cyclase (which converts adenosine triphosphate to cyclic AMP), guanylate cyclase selectively stains positive for lymphatic capillaries and therefore may be another useful histochemical marker to differentiate dermal lymph from blood capillaries.
