Abstrakt: Guanosine 3′,5′-monophosphate (cyclic GMP, cGMP) was localized in bone cells by the use of an immunoglobulin-enzyme bridge method. We observed that in cat alveolar bone most osteoblasts did not stain for cGMP, while adjacent periodontal cells displayed cytoplasmic as well as nuclear staining. Numerous osteocytes contained diffuse reaction products over most or all of the cellular area. The method used in this study may be helpful in identifying specific hard tissue cell types whose function(s) involve cGMP.
