IPSC and organoid models for unravelling brain disease mechanisms

image-2The use and generation of induced pluripotent stem cell (IPSC)-generated cells has increased exponentially. The possibility of generating patient-derived IPSC lines followed by differentiation into desired cell types has the promise to provide new and ground-breaking insights into disease mechanisms and can facilitate the development of therapeutic approaches. We use IPSC approaches to generate neurons and glial cells for different translational projects. For example, motor neurons for research into ALS, SMA and immune system-mediated motor neuron diseases. Differentiated cultures generated from control and patient IPSCs are subjected to numerous analyses, including electrophysiology (patch clamp, MEA), calcium imaging, immunocytochemistry and RNAseq.

Furthermore, genome editing approaches, such as CRISPR/CAS9, are used to generate isogenic controls or cell lines carrying specific mutations. IPSCs are also used to generate cerebral and cortical organoids allowing analysis of neuronal and glial cell morphology and function in a three-dimensional environment. Analysis of neuronal morphology is facilitated by Ultramicroscope lightsheet imaging present in our lab.

The IPSC, organoid and light-sheet imaging is organized in a research facility, the MIND facility. This facility is financially supported by the UMC Utrecht Brain Center, UMC Utrecht and Utrecht University.
