3D Cell Models for Fundamental and Applied Research

Based on 20 years of research on mouse skeletal muscle, neuromuscular junctions, their innervation by sympathetic neurones, and mechanisms of postsynaptic protein trafficking, we are now focusing on 3D-cell models for fundamental and applied pharmaceutical research, often in cooperation with academic and industrial partners. These cell-based models are mainly for neuronal or cancer research and range from spheroids over chip-based assays up to complex cocultures and organoids. Technological foci are on development of adequate cell culturing techniques, including 3D bioprinting, but also optical tissue clearing protocols, 3D and 4D confocal and light sheet microscopy, and AI-based automated image analysis. In the context of neurosciences, we have been concentrating on the establishment of models for the neuromuscular junction (NMJ).
