项目摘要
Summary (Overall)
The overarching goal of this Program Project is to better understand the Developmental Mechanisms of
Trachea-Esophageal Birth Defects (TEDs) in order to advance our knowledge of their etiology, enhance
diagnosis, improve treatment, and inform strategies to generate TE tissue from human pluripotent stem cells
(PSCs) that might ultimately be used for transplantation The trachea and esophagus (TE) arise from the
separation of a common foregut tube during early fetal development. Defects in TE morphogenesis cause a
spectrum of life-threatening TEDs that prevent proper breathing and feeding in newborns. TEDs including
esophageal atresia (EA) and trachea-esophageal fistula (TEF) are corrected by invasive neonatal surgery and
are often associated with long-term co-morbidity. The etiology of TEDs, which occur in ~1:3500 births, is poorly
understood. Although there is compelling evidence for a major genetic component, causative mutation are.
only known in ~12% of TED cases worldwide. Moreover, even for the few cases where the genes involved
have been identified, such as the HEDGEHOG (HH) and BMP signaling pathway genes, how these regulate
fetal TE morphogenesis, and hence the structural basis of TEDs, is unknown. The long-term goal of this project
is to determine the genetic and developmental mechanisms underlying TEDs in order to improve our
understanding of their etiology, enhance diagnosis, improve treatment, and inform strategies to generate
human tissue from pluripotent stem cells (PSCs) that might ultimately be used for transplantation. We have
assembled an experienced and highly collaborative multi-disciplinary team of clinicians, geneticists,
bioinformaticians, data scientists, imaging experts, developmental biologists and human stem cell biologists to
tackle this problem using an innovative combination of human genetics, neonatal MRI, animal modeling in
Xenopus and mouse, quantitative cell biology, genome editing and human PSCs derived esophageal
organoids. This will be a Multi-PI project centered at Cincinnati Children’s Hospital Medical Center (CCHMC) in
collaboration with Columbia University Medical Center. The Multi-PIs will be: Aaron Zorn PhD (contact PI;;
CCHMC), Paul Kingma MD PhD (CCHMC), James Wells PhD (CCHMC) and Wendy Chung MD PhD
(Columbia). These combined expertise and resources creates a synergistic program not found at any single
institution. We propose 3 innovative and highly synergistic projects and a Genomics Core to reveal the genetic,
molecular and cellular basis of TED
· Project-1: Comprehensive phenotypic and genetic assessment of TED patients.
· Project-2: Modeling the molecular and cellular mechanisms of TEDs in animals.
· Project-3: Modeling TE birth defects in human pluripotent stem cell (PSC)-derived fetal tissues.
· Integrated Genomics Core and Administrative Core
摘要(总体)
该计划项目的总体目标是更好地了解儿童的发展机制
气管-食管出生缺陷 (TED) 为了增进我们对其病因学的了解,增强
诊断、改善治疗并提供从人类多能干细胞生成 TE 组织的策略
最终可能用于移植的 (PSC) 气管和食管 (TE) 源自
胎儿早期发育过程中共同前肠管的分离导致 TE 形态发生的缺陷。
一系列危及生命的 TED 会妨碍新生儿正常呼吸和喂养,包括 TED。
食管闭锁(EA)和气管食管瘘(TEF)通过侵入性新生儿手术进行矫正
通常与长期合并症相关。TED 的病因学在约 1:3500 的出生中发生,目前尚不清楚。
尽管有令人信服的证据表明主要遗传成分是致病突变。
此外,即使对于少数涉及基因的案例,也只有约 12% 的 TED 案例才为人所知。
已经确定,例如HEDGEHOG(HH)和BMP信号通路基因,它们如何调节
胎儿 TE 形态发生以及 TED 的结构基础尚不清楚 该项目的长期目标。
是确定 TED 背后的遗传和发育机制,以改善我们的
了解其病因,加强诊断,改善治疗,并制定策略以产生
我们拥有来自多能干细胞(PSC)的人体组织,最终可能用于移植。
组建了一支经验丰富、高度协作的多学科团队,由精英、遗传学家、
生物信息学家、数据科学家、成像专家、发育生物学家和人类干细胞生物学家
使用人类遗传学、新生儿 MRI 和动物模型的创新组合来解决这个问题
非洲爪蟾和小鼠、定量细胞生物学、基因组编辑和人类 PSC 来源的食管
这将是一个以辛辛那提儿童医院医疗中心 (CCHMC) 为中心的多 PI 项目。
与哥伦比亚大学医学中心合作的多位 PI 将是:Aaron Zorn 博士(联系 PI;;
CCHMC)、Paul Kingma 医学博士 (CCHMC)、James Wells 博士 (CCHMC) 和 Wendy Chung 医学博士
(哥伦比亚)。这些专业知识和资源的结合创造了一个前所未有的协同计划。
我们提出 3 个创新且高度协同的项目和一个基因组学核心来揭示遗传、
TED 的分子和细胞基础
· 项目-1:TED 患者的综合表型和遗传评估。
· 项目-2:模拟动物 TED 的分子和细胞机制。
· 项目 3:在人类多能干细胞 (PSC) 衍生的胎儿组织中模拟 TE 出生缺陷。
· 集成基因组学核心和管理核心
