PG - 51-63 AB - Using NADPH-diaphorase histochemistry, the present study describes development of olfactory and vomeronasal systems in postnatal opossums, Monodelphis domestica. NADPH-dependent staining is absent at and around the time of birth. By 2 weeks of age and through adulthood, intense staining is seen along the luminal surface of the olfactory epithelium (OE) and of the vomeronasal sensory epithelium (VNE), as well as in Bowman's glands of the OE. Staining of the adult VNE is not homogeneous; it is restricted to the superficial 2/3 of the epithelium. At 2 weeks of age, staining in the brain is seen only at the surface of the ventricles and in blood vessels. At 1 month of age and through adulthood, staining of varying intensity is seen in individual olfactory bulb glomeruli, although the incoming olfactory axons are relatively unstained. Interestingly, whereas at 30 days of age, staining of the accessory olfactory bulb (AOB) glomeruli is uniform, 2 weeks later and in the adult, NADPH staining is concentrated in the rostral half, with little or no staining observed in the posterior portion. Darkly stained periglomerular cells are seen throughout the extent of the differentially-stained glomerular layer. From 30 days of age and through adulthood, intense NADPH staining is also observed in the islands of Calleja, as well as in cells of the dorsal cortex, often associated with the path of the rostral migratory stream.
