The rat possesses hemochorial placentation with deep intrauterine trophoblast cell invasion and trophoblast-directed uterine spiral artery remodeling; features shared with human placentation. Recognition of these similarities spurred the establishment of in vitro and in vivo research methods using the rat as an animal model to address mechanistic questions regarding development of the hemochorial placenta. The purpose of this review is to provide the requisite background to help move the rat to the forefront in placentation research.
大鼠具有血绒毛膜胎盘,其特点是深层的宫内滋养细胞浸润和滋养细胞定向的子宫螺旋动脉重塑;这些特征与人类胎盘的特征相同。对这些相似性的认识促使人们建立了使用大鼠作为动物模型的体外和体内研究方法,以解决关于血绒毛膜胎盘发育的机制问题。本文综述的目的是提供必要的背景知识,以帮助推动大鼠在胎盘研究中发挥主导作用。
