胎儿发育可能受到母体和胎儿之间胎盘界面不良事件的影响。然而,目前尚不清楚母亲和胎儿之间是如何通过胎盘进行交流的。人类胎盘屏障的体外模型可以帮助我们理解并重建具有生物功能和血管系统的三维(3D)结构,但尚未报道。在这里,我们提出了一个三维血管化的人原发性胎盘屏障模型,可以在1天内构建。我们说明了我们的模型与妊娠早期人类胎盘的相似之处,无论是在结构上,还是在对改变的氧气做出反应的能力上,以及在分泌导致包括胚胎皮质神经元在内的屏障损伤细胞的因素上。我们使用这个模型来强调胎盘内的滋养细胞和内皮细胞可能在胎母对话中发挥作用的可能性。
Fetal development may be compromised by adverse events at the placental interface between mother and fetus. However, it is still unclear how the communication between mother and fetus occurs through the placenta.In vitro- models of the human placental barrier, which could help our understanding and which recreate three-dimensional (3D) structures with biological functionalities and vasculatures, have not been reported yet. Here we present a 3D-vascularized human primary placental barrier model which can be constructed in 1 day. We illustrate the similarity of our model to first trimester human placenta, both in its structure and in its ability to respond to altered oxygen and to secrete factors that cause damage cells across the barrier including embryonic cortical neurons. We use this model to highlight the possibility that both the trophoblast and the endothelium within the placenta might play a role in the fetomaternal dialogue.
