“…There were clear structural differences between the arrangements of the cells in these two anatomical distinct areas. These differences in the superficial pineal gland have occasionally been described by others (Calvo and Boya, 1981a,b; Reiter, 1990; Alvarez‐Uría et al., 1991). This is the first time scanning electron microscopy has been used to describe the cortical and medullary regions of the rat pineal gland.…”

“…The pineal complex consists of three portions: (a) the deep pineal or lamina intercalaris, which extends toward (b) the pineal stalk, and (c) the pineal organ proper or superficial pineal. Among mammals, these three portions are distinguishable and show considerable variations in terms of their relative sizes (Alvarez‐Uría et al., 1991).…”

“…It remains controversial as to whether the superficial pineal gland of mammals possesses both a cortex and medulla; while some authors claim the existence of both a cortical and medullary region, other authors deny their existence (Matsushima and Reiter, 1975, 1978; Alvarez‐Uría et al., 1991).…”

The presence of a cortex and medulla in the superficial pineal gland has been a controversial point in the morphology of this structure in mammals. The published reports indicate contradictory data especially in rodents. In this study the pineal gland of 15-day-old male rats (Rattus norvegicus) were studied, using scanning electron microscopy, in an attempt to determine whether or not a cortex and medulla are apparent in the pineal gland of young rats. The superficial pineal gland of the 15-day-old rat exhibited both a cortex and a medulla; these areas exhibited different structural organizations. The cortex had a thickness of 40-80 microm and the cells did not show a particular arrangement. The center of the gland was composed of a medulla, which had a width of 1000-1200 microm, and consisted of cells arranged in cords; its morphology was distinctly different from that of the cortex.

The expression of somatostatin mRNA was investigated in rat pineal cells after 1 week in culture, using reverse transcription of mRNA into cDNA and the polymerase chain reaction. The positive expression in cultured pineal cells demonstrates the capacity of this gland to synthesize somatostatin in denervated cells. Thus, apart from the neural origin of pineal somatostatin, which has been described in detail in the bovine species, a parenchymal source is demonstrated.
