项目摘要
ABSTRACT/PROJECT SUMMARY
This application presents a five-year mentored research and training plan that will prepare Dr. Cathryn
Cadwell to be a leader in the field of cortical development and circuit assembly. Dr. Cadwell completed her MD
and PhD in Neuroscience at Baylor College of Medicine, where she studied the role of cell type and cell
lineage in shaping cortical circuits in the lab of Dr. Andreas Tolias, and is now completing her clinical fellowship
in Neuropathology at the University of California, San Francisco. Dr. Cadwell’s long-term career goal is to
advance our understanding of the pathological processes underlying neurodevelopmental and neuropsychiatric
disorders. This project will facilitate foundational discoveries for her independent research program, as she
seeks to delineate the mechanisms and functional consequences of cortical areal specification.
Different areas of the human brain give rise to unique cognitive abilities. For example, expansion of the
lateral prefrontal cortex (PFC) in humans is thought to underlie higher-order cognitive processes such as
decision-making, planning and working memory. Recent data has implicated retinoic acid (RA), a derivative of
vitamin A, as a key player in the early development of the PFC in humans; however, the precise mechanism by
which RA specifies PFC identities is unknown. This proposal leverages a human induced pluripotent stem cell–
derived cerebral organoid model, which recapitulates many aspects of early human brain development, to test
the hypothesis that RA acts in a cell type–specific manner to specify PFC identities. Using this model, Dr.
Cadwell proposes to 1) identify the nuclear receptors and gene regulatory elements that mediate RA signaling
in human cortical progenitors and 2) determine whether PFC-like areal fate is stable after RA induction. This
work will generate fundamental knowledge about the role of RA in patterning the cerebral cortex, and may
provide insights into neurodevelopmental disorders associated abnormal cortical areal specification.
The proposed career development plan includes training in cerebral organoid models, epigenetic
techniques and analysis of large-scale data sets. Dr. Cadwell will learn all of the skills needed for an
independent research career, including supervising trainees and staff, grant writing, and scientific
communication. She has assembled a world-class mentorship team with complementary expertise in
organoids and human brain development (Primary mentor, Dr. Tomasz Nowakowski), molecular mechanisms
of cortical development and patterning (Co-mentor Dr. John Rubenstein and Advisory Committee Member Dr.
Sam Pleasure), gene regulation (Advisory Committee Member Dr. Nadav Ahituv), analysis of large-scale
genomic data (Dr. Katie Pollard), and neuropathology of neurodevelopmental disorders (Dr. Eric Huang). Dr.
Cadwell, her mentors, and the Department of Pathology at UCSF are fully committed to this proposal and to
her goal of becoming an independent physician-neuroscientist by the completion of this training period.

旧金山加利福尼亚大学神经病理学博士。卡德威尔博士的长期职业目标是
增进我们对神经发育和神经精神病理过程的理解
失调。该项目将促进她的独立研究计划的基础发现,因为她
旨在描述皮质区域规范的机制和功能后果。
人脑的不同区域产生独特的认知能力。例如,扩展
人类的外侧前额皮质(PFC)被认为是高阶认知过程的基础,例如
决策、计划和工作记忆。最近的数据表明视黄酸 (RA) 是一种衍生物
维生素 A,作为人类 PFC 早期发育的关键参与者;然而,精确的机制是
哪个 RA 指定 PFC 身份尚不清楚。该提案利用了人类诱导多能干细胞——
衍生的大脑类器官模型,概括了早期人类大脑发育的许多方面,以测试
假设 RA 以细胞类型特异性方式发挥作用来指定 PFC 身份。使用这个模型,博士。
Cadwell 建议 1) 鉴定介导 RA 信号传导的核受体和基因调控元件
2) 确定人类皮质祖细胞中 PFC 样区域命运在 RA 诱导后是否稳定。这
这项工作将产生关于 RA 在大脑皮层模式化中的作用的基础知识,并且可能
提供对与异常皮质区域规范相关的神经发育障碍的见解。
拟议的职业发展计划包括大脑类器官模型、表观遗传学的培训
大规模数据集的技术和分析。卡德威尔博士将学习成为一名医生所需的所有技能
独立研究生涯,包括监督受训者和工作人员、资助写作和科学
