Research Interests

Neural stem cells (NSCs) generate new neurons throughout life (reviewed in: Denoth-Lippuner and Jessberger, 2021 Nature Reviews Neurosc). We use imaging-, genome editing-, and transgenesis-based approaches as well as cellular models of human diseases using pluripotent embryonic cells to study the molecular and cellular framework of NSC biology in the developing and adult brain. Aim of our research is to understand how physiologic and disease-associated alterations of neurogenesis are translated into stem cell-associated plastic changes in the developing and adult brain on a molecular, cellular, and behavioral level.

Cellular principles of stem cell activity in the brain

We pioneered intravital imaging of individual NSCs and their progeny in the mouse hippocampus and provided direct evidence for extended self-renewal of NSCs. Together with molecular tools (such as single cell RNA-sequencing), we currently use in vivo imaging to characterize the functional contribution of new vs. old granule cells for hippocampal circuit activity and how stem cell dynamics are affected by advancing age.

Consequences of previous cellular experiences and age on stem cell behavior

We provided the first description of a diffusion barrier in the endplasmic reticulum (ER) in mammalian cells that appears to be involved in the asymmetric segregation of cellular age. We currently aim to identify the molecular and behavioral consequences of previous cellular experiences (such as cell divisions and/or biological age) on somatic stem cells. We developed novel tools to identify the cell division history of stem cells in vivo (e.g., the iCOUNT system) and currently develop novel technology to visualize the cellular age of individual cells in complex tissues.

Molecular control of neural stem cell activity

Our previous work identified several pathways/genes that are critically involved in distinct development steps during neurogenesis. We pioneered work to characterize a critical role for lipid metabolism for neural stem cell behavior. We currently use mouse genetics and regionalized organoids derived from human embryonic stem cells (hESCs) to characterize NSC behavior in complex tissues. Experiments are based on mouse genetics, hESC genome-editing, long-term imaging, and single cell RNA-sequencing approaches.
