The Schäfer Lab focuses on advancing novel stem cell-based technologies to push the boundaries for personalized research on human-specific brain disorders and to identify strategies for facilitating brain repair.
Studying prenatal human brain development remains a challenge due to limited access to live human brain tissue and ethical constraints on research using human embryos. Recent advances in stem cell biology have revolutionized the field of human developmental biology by allowing us to generate three-dimensional models that recapitulate structural organization of various organs, including the brain.
Personalized Human Disease Models to Study Brain Disorders. While specific phenotypes thought to be associated with neuropsychiatric disorders are currently the subject of active research, the question of whether such disease-associated changes represent the consequences of an ongoing and dynamically aberrant developmental process has received less attention. Our lab focuses on dissecting the cellular and developmental origin of mental disorders by using novel approaches that combine comprehensive clinical assessments with patient-specific biological phenotyping. We are particularly interested to dissect cell type-specific principles that govern the dynamic control of human brain development and at the same time introduce a selective vulnerability for human-specific disorders. Identifying “when” and “where” during development a disease signature first emerges has the potential to facilitate pre-symptomatic or, potentially prenatal, diagnosis and risk assessment. We envision that the novel strategies developed here will lead to advances i n mechanism discovery and diagnosis of mental disorders to ensure an early initiation of personalized treatment programs.
Advanced Neuro-Immune Models for Developing Therapies and Guiding Brain Repair. A specialized population of tissue-resident immune cells known as microglia are thought to play a central role in brain development, homeostasis and tissue repair. Our lab is particularly interested to develop technologies that allow us to study how these tissue-resident immune cells communicate with the human brain. We want to understand the cellular and molecular mechanisms by which microglia orchestrate developmental processes in order to devise targeted strategies for facilitating brain repair.
