The ultrastructure of the dog pineal gland from the first postnatal day to the seventh month is described. In the first postnatal stages, pineal parenchyma only shows immature proliferative cells with abundant cytoplasmic glycogen. Nerve fibers are seen in the pineal connective tissue spaces. The differentiation of the dog pineal cell types begins in the first postnatal week. Both pinealocytes and pigmented cells are first seen on the fourth postnatal day. The pineal astrocytes are observed on the tenth day. Immature cells are still found in the pineal gland of 1 mo-old dogs. The differentiation of the dog pineal cell types is completed by the second postnatal month.
描述了从出生后第一天到第七个月的犬松果体超微结构。在出生后的最初阶段，松果体实质仅显示具有丰富细胞质糖原的未成熟增殖细胞。在松果体结缔组织间隙中可见神经纤维。犬松果体细胞类型的分化始于出生后的第一周。松果体细胞和色素细胞最早在出生后第四天出现。松果体星形胶质细胞在第十天被观察到。在1月龄犬的松果体中仍可发现未成熟细胞。犬松果体细胞类型的分化在出生后第二个月完成。
