ABSTRACT Spontaneous preterm birth (PTB) affects approximately 11% of all births and is a significant contributor to neonatal mortalities and morbidities. Current interventions in PTB are designed to stop maternal uterine contractions to delay delivery but have limited success. Infection and host inflammatory responses are the major factors predisposing to PTB. Inflammation of the feto-maternal interface (FMi), specifically at the chorio- decidual interface, in response to various risk factors can compromise immune tolerance that maintains pregnancy, amplify inflammatory response, and trigger pathways of PTB. Multiple drugs in preclinical trials have shown that they can reduce inflammation and delay PTB. However, challenges in testing drug transport, metabolic changes, and teratogenicity have hindered PTB drug development. Unfortunately, current in vitro cell culture models and animal models have several limitations, and focus is given only to placental transport of drugs. To overcome these limitations, we have been successfully developing several tissue chip models of the FMi using primary human cells and have demonstrated that they can recapitulate the functions and responses of healthy and disease states of the FMis. However, our tissue chip models lack high-throughput screening (HTS) capabilities. This proposal will develop a high-throughput 3D bioprinted FMi tissue chip in a 96-well format, which can be used for HTS of large drug libraries, while keeping the key advantages of FMi tissue chips in mimicking in utero structure and functions. We will specifically focus on the chorio-decidua interface, motivated by two recent findings: 1) drug transport efficiently occurs through the chorio-decidual interface (FMi) like that seen in placenta, where previously it was thought that most transport occurs exclusively through placenta and 2) efficacy of Pravastatin (drug tested here) transported through this FMi is substantially higher than through placenta in reducing inflammation. In the UH2 phase, the healthy and disease (infection and inflammation-driven PTB) tissue chip model will be developed together with NCATS' intramural investigators, combining our expertise of PTB, FMi cells, tissue chip development, cell/ECM bioprinting, and high-throughput drug screening. In the UH3 phase, we will utilize the tissue chip to screen up to 1,000 drug compounds at NCATS, followed by further analysis of selected drugs of highest interest using our advanced (but lower throughput) FMi tissue chip model that is best suited for mechanistic studies. Our tissue chip model is expected to enable rapid testing of candidate therapeutics to bring epxperimental drugs more quickly to clinical trials.

抽象的 自发性早产 (PTB) 影响约 11% 的新生儿，是导致早产的重要因素 新生儿死亡率和发病率。当前 PTB 的干预措施旨在阻止产妇子宫收缩 宫缩以延迟分娩，但效果有限。感染和宿主炎症反应是 诱发PTB的主要因素。胎儿-母体界面（FMi）的炎症，特别是在绒毛膜处 蜕膜界面，响应各种风险因素可能会损害维持免疫耐受 妊娠、放大炎症反应并触发 PTB 途径。多种药物进入临床前试验 已表明它们可以减少炎症并延迟 PTB。然而，测试药物转运的挑战， 代谢变化和致畸性阻碍了 PTB 药物的开发。不幸的是，目前的体外细胞 培养模型和动物模型有一些局限性，并且仅关注胎盘转运 药物。为了克服这些限制，我们已经成功开发了几种组织芯片模型 FMi 使用原代人类细胞，并证明它们可以重现功能和反应 FMis 的健康和疾病状态。然而，我们的组织芯片模型缺乏高通量筛选 （高温超导）能力。该提案将在 96 孔中开发高通量 3D 生物打印 FMi 组织芯片 格式，可用于大型药物库的 HTS，同时保留 FMi 组织的关键优势 模仿子宫结构和功能的芯片。我们将特别关注绒毛膜-蜕膜界面， 受到两项最近发现的推动：1）药物转运通过绒毛膜-蜕膜界面（FMi）有效发生 就像在胎盘中看到的那样，以前人们认为大多数运输完全通过胎盘发生 胎盘和 2) 通过该 FMi 运输的普伐他汀（此处测试的药物）的功效显着更高 比通过胎盘减少炎症更有效。在UH2阶段，健康者和疾病者（感染和 炎症驱动的 PTB）组织芯片模型将与 NCATS 的壁内研究人员一起开发， 结合我们在 PTB、FMi 细胞、组织芯片开发、细胞/ECM 生物打印和高通量方面的专业知识 药物筛选。在UH3阶段，我们将利用组织芯片在以下时间筛选多达1,000种药物化合物 NCATS，然后使用我们先进的（但较低的 最适合机械研究的 FMi 组织芯片模型。我们的组织芯片模型预计 能够快速测试候选疗法，从而更快地将实验药物投入临床试验。
