总结(总体)
该计划项目的总体目标是更好地了解
气管-食管出生缺陷(TEDs),以提高我们的病因学知识,加强
诊断,改善治疗,并为从人类多能干细胞产生TE组织的策略提供信息
气管和食管(TE)起源于肺动脉高压,
在早期胎儿发育过程中共同的前肠管分离。 TE形态发生的缺陷导致
一系列危及生命的TED,阻止新生儿正确的呼吸和喂养。 TED包括
食管闭锁(EA)和气管-食管瘘(TEF)通过侵入性新生儿手术纠正,
通常与长期并发症有关。TED的病因,发生在约1:3500出生,是不好的,

仅在全球约12%的TED病例中发现。 此外,即使在少数情况下,基因参与

英文摘要
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
