Radboud university medical center
Researchers of the Radboud university medical center (Radboudumc) focus on today’s scientific health challenges as well as keeping an eye on emerging diseases of the future. With the mission ‘to have a significant impact on healthcare’ and a strategic focus on personalized healthcare through ‘the patient as partner’, the core activities of patient health care, research and education are bundled in 17 disease-oriented research themes in which fundamental researchers and clinicians meet regularly and integrate their knowledge and expertise to realize important improvements in patient-directed science, diagnosis and treatment. The disease-oriented research themes include cancer development, rare cancers, digestive tract, urological and women’s cancers, infectious, inflammatory, mitochondrial and alzheimer’s diseases, renal, sensory, neurodevelopment and stress-related disorders, and vascular damage. Radboudumc consists of 11.000 colleagues, 50 departments, 3000 students and 1000 beds.

Embedding Organ-on-Chip technology in research policy
For many themes, the Organ-on-Chip technology forms the interphase between molecular studies and physiological studies in patients. Therefore, the Stem Cell and Differentiation Technology Center has been set up and is sponsored by the department of Human Genetics and Radboudumc. In the human movement theme, all projects involve the use of Brain on Chip technology in which neuronal networks of individual patients are phenotyped with the ultimate aim to perform drug screening for individual patients rather that disease specific, i.e. getting to personalized medicine. To increase Organ-on-Chip research and collaboration with the UTwente, the Radboudumc and UTwente provided 4 collaborative TURBO grants.
