The mammillary bodies are already shaped in the last stages of the fetal development, and you can differentiate clearly in them the medial mammillary nucleus (MMN) and lateral mammillary nucleus (LMN). All this allow to study the variations in cellular density, the relation between neuronal and glial cells, so as the number of nucleoli present in the neuronal cells and the nucleolar area variations through the postnatal development (0N, 2N, 4N, 8N, 16N and adult). The results show, demonstrate a different behaviour in the cellular stabilization and migration of the MMN and LMN, so as a cellular differentiation after 4N in both nucleus. All this is discussed with the data obtained from the nucleolar activity, as an index of synthesis and reflection of the neuronal maturing.
乳头体在胎儿发育的最后阶段已形成,在其中可以清楚地区分内侧乳头核(MMN)和外侧乳头核(LMN)。所有这些都有助于研究细胞密度的变化、神经元细胞与神经胶质细胞之间的关系,以及神经元细胞中核仁的数量和核仁面积在出生后发育过程(0N、2N、4N、8N、16N和成年期)中的变化。结果表明,MMN和LMN在细胞稳定和迁移方面表现出不同的行为,并且在4N之后两个核中都出现了细胞分化。所有这些都结合从核仁活性获得的数据进行了讨论,核仁活性作为神经元成熟的合成指标和反映。
