Resumen: The ontogenesis of the pineal gland of 20 bovine embryos (Bos taurus) has been analysed from 160 days of gestation to birth by means of optical microscopy and immunohistochemical techniques. For this study, the specimens were grouped into two stage in accordance with the most relevant histological characteristics: Stage 1 (160 to 200 days of prenatal development) and Stage 2 (220 days of prenatal development to birth). At 160 days of gestation some rounded structures with a central lumen, which we refer to as glandular rosettes, begin differentiation from the epithelium of the pineal recess, experiencing an extraordinary increase in number and size at 200 days of intrauterine life. In the interior of the pineal parenchyma we observed some morphologically rounded cells with oval euchromatic nuclei and a well-differentiated nucleolus that we refer to as the pinealoblasts. We also observed other cells characterised by the presence of low cytoplasm and rounded and highly stained nuclei th...
