Disease Stem Cells Models and Embryology

Research focus

Our research activities are focused on disease modeling using induced pluripotent stem cells (iPSC) from patients and their CRISPR-Cas9 gene edited controls. We have a specific disease-oriented focus on Alzheimer’s disease (AD) Frontotemporal dementia (FTD), Glaucoma, Epilepsy and Schizophrenia.


Within these diseases we are investigating cell type specific pathologies in neurons, astrocytes and microglia. We are conducting those studies in 2D and in 3D organoid structure. We are especially keen on understanding overlapping dysfunctions amongst different types of dementia and identification of key players in disease pathways. We believe that comprehensive understanding of such molecular commonalities may provide opportunities for novel interventions that are beneficial for an array of related diseases facilitating cost effective drug development. Furthermore, our lab is working in early embryology and epigenetic alterations leading to developmental abnormalities and infertility.

Current projects

Our main research focus is on Alzheimer’s disease (AD). Recently, we are focusing more on idiopathic AD where we are investigating the role of RhoA and genetic risk single nucleotide polymorphisms in iPSC derived neurons, astrocytes, and microglia (“RhoAD” funded by the Novo Nordisk Foundation). Additionally, we are investigating posttranslational modifications (PTM), miRNAs and early changes in synaptic pruning in cerebral organoids derived from both familial AD patient iPSC and their isogenic controls as well as idiopathic AD patient iPSC (“Developnoid” funded by the Lundbeck Foundation). This project is a collaborative grant with partners at the University of Copenhagen (Martin Røssel-Larsen) and at Cambridge University (Madeline Lancaster).

Within the Developnoid collaborative consortium, we are, furthermore, establishing iPSC from epilepsy patients and will perform PTM and miRNA analyses on cerebral organoids to map affected biological pathways, which can be pharmacologically targeted to interfere into the disease pathology.

Funded by the Velux Foundation and Øjenforeningen, we are investigating the role of mitochondria in development and progression of Glaucoma implementing iPSC derived retinal organoids. Here we are interested in two main questions. 1) Can patient fibroblasts be surrogate measures for Glaucoma prediction and 2) How do mitochondria deficits arise and can we identify pharmacological intervention strategies. This project is in close collaboration with Miriam Kolko (Rigshospital and Dep of Pharmacology and Drug Design, UCPH).

Funded by the Danish Research Council, we are participating in a project led by Jan Gorodkin, UCPH investigating epigenetic implications in human iPSC and their impact on CRISPR-Cas9 on and off target efficiency.

Additionally, we are investigating the consequences and treatment options in rare childhood epilepsies in collaboration with Rikke Møller at the Danish epilepsy center and Jakob Balslev Sørensen. Within this project we have generated via CRISPR-Cas9 precision gene editing loss and gain of function mutations in disease relevant genes (funded by the Lundbeck Foundation & “PREMED” Novo Nordisk Foundation).

Finally, we are working with the generation of animal iPSC, and we have successfully generated porcine iPSC and canine iPSC-like cells. The canine iPSC work has been focused on establishing dogs with canine cognitive dysfunction (CCD) as natural models for human AD (funded by the Danish Research Council). The porcine iPSCs have been implemented in studies to generate non-immunogenic iPSC (collaboration with LifePharm and the Novo Nordisk Stem Cell Department). We are currently embarking on the generation of capuchin monkey iPSC to include into our comparative neurodevelopmental studies in schizophrenia and epilepsy, but also to study brain evolutionary aspects (collaboration with Fabianna Bressan, University São Paulo)

The EggSphere project is a FP1 project funded by the Danish Council for Independent Research/Natural Sciences, and it investigates the function of the oocyte’s nucleolus in embryonic development. The pig, in which the egg’s morphology and biology resembles its human counterpart, will be used to study the content of the nucleolus as well as the developmental competence conveyed by this structure.
