摘要

胎盘是子宫内的一个短暂器官,只有在妇女怀孕时才会有一系列活动。它是一个由母体和胚胎成分组成的盘状杂交结构。胚泡着床后,它在子宫的系膜侧发育,以保持两个遗传上不同的实体——母亲和胚胎——分离但相连。胚泡着床后胎盘形成和发育的开始和进展与胚胎的时间发育阶段一致。它逐渐获得在母体环境中同步执行血管、呼吸、肝脏、肾脏、内分泌、胃肠、免疫和物理屏障功能的能力,这些功能对胎儿的发育、生长和安全至关重要。当胎盘对胚胎生长和存活的支持作用完成后,子宫将胎盘排出体外;这通常是婴儿的出生。尽管在胚胎着床后的妊娠过程中,它在胎儿发育和生存中起着不可替代的作用,但它是如何形成、成熟、执行所有活动并开始失效的,目前仍不清楚。因此,对胎盘正常发育、结构和功能方面的详细了解可以避免胎盘引起的妊娠问题。

Development of the Mouse Placenta.

Placenta forms as a momentary organ inside the uterus with a slew of activities only when the woman is pregnant. It is a discoid-shaped hybrid structure consisting of maternal and embryonic components. It develops in the mesometrial side of the uterus following blastocyst implantation to keep the two genetically different entities, the mother and embryo, separated but connected. The beginning and progression of placental formation and development following blastocyst implantation coincides with the chronological developmental stages of the embryo. It gradually acquires the ability to perform the vascular, respiratory, hepatic, renal, endocrine, gastrointestinal, immune, and physical barrier functions synchronously that are vital for fetal development, growth, and safety inside the maternal environment. The uterus ejects the placenta when its embryonic growth and survival supportive roles are finished; that is usually the birth of the baby. Despite its irreplaceable role in fetal development and survival over the post-implantation progression of pregnancy, it still remains unclear how it forms, matures, performs all of its activities, and starts to fail functioning. Thus, a detailed understanding about normal developmental, structural, and functional aspects of the placenta may lead to avoid pregnancy problems that arise with the placenta.

期刊介绍: "Advances in Anatomy, Embryology and Cell Biology" presents critical reviews on all topical fields of normal and experimental anatomy including cell biology. The multi-perspective presentation of morphological aspects of basic biological phenomen in the human constitutes the main focus of the series. The contributions re-evaluate the latest findings and show ways for further research.
