项目摘要

Project Summary The development of the thyroid gland from anterior endoderm is an essential step in development that allows for the production of thyroid hormones around week 12 in utero in humans. Unfortunately, in about 1/4000 births genetic mutations that affect this development pathway lead to congenital hypothyroidism requiring lifelong thyroid hormone replacement therapy. Thus, a better understanding of thyroid follicular cell development could lead to a process where genetic editing and cellular therapy could provide treatment for congenital hypothyroidism (CH). Our work in this area has utilized a directed differentiation approach and has identified bone morphogenic protein and fibroblast growth factor as key mediators of thyroid follicular cell lineage development across species resulting in functional murine thyroid follicular cells that can rescue athyreotic mice. In this proposal, we now turn our attention exclusively to human thyroid follicular cell development and propose three Specific Aims that will allow for the pre-clinical development of functioning human thyroid follicular cells derived from human induced pluripotent stem cells (iPSCs), In the first Aim we will utilize a novel lineage tracing methodology to understand how developing human thyroid follicular acquire their cell fate and to ensure that the process in iPSC parallels that in vivo. In the second Aim we will prove that the human thyroid follicular cells derived from iPSCs are fully able to produce thyroid hormones in vitro and can be transplanted into immunodeficient athyreotic mice to rescue their hypothyroidism. Finally, in the third Aim we will demonstrate pre- clinically that derived iPSCs from a patient with CH can be genetically corrected and re-introduced via transplant to function normally. Together completion of these Aims will provide key insight into the possibilities of iPSC derived cellular therapy for the treatment of CH and enhance our understanding of the development endodermal- derived tissues in humans.

项目摘要甲状腺从前内胚层的发展是开发的重要步骤，可以甲状腺激素在人类的子宫内的第12周左右生产。不幸的是，大约有1/4000个出生影响这种发育途径的基因突变导致先天性甲状腺功能减退症需要终身甲状腺激素替代疗法。因此，更好地了解甲状腺卵泡细胞的发育可能导致遗传编辑和细胞疗法可以为先天性提供治疗的过程甲状腺功能减退症（CH）。我们在这一领域的工作采用了定向分化的方法，并确定了骨形态发生蛋白和成纤维细胞生长因子作为甲状腺卵泡细胞谱系的关键介体跨物种的发展，导致功能性鼠甲状腺卵泡细胞，可以挽救肌动蛋白小鼠。在此提案中，我们现在将注意力专门转移到人类甲状腺卵泡细胞的发展上并提出三个特定的目的将允许人类甲状腺卵泡细胞的临床前发展源自人类诱导的多能干细胞（IPSC），在第一个目的中，我们将利用一种新型的谱系跟踪了解人类甲状腺卵泡如何获得细胞命运并确保 IPSC中的过程与体内相似。在第二个目标中，我们将证明人甲状腺卵泡细胞源自IPSC的能力完全能够在体外产生甲状腺激素，并且可以移植到免疫缺陷的静脉小鼠可营救其甲状腺功能减退症。最后，在第三个目标中，我们将证明临床上可以通过移植对CH患者衍生的IPSC进行遗传校正和重新引入正常功能。这些目标共同完成将为IPSC的可能性提供关键的见解衍生的细胞疗法，用于治疗CH并增强我们对内皮胚层发育的理解人类中的组织。
