Research focus

Using reprogramming to model diseases of the human brain

Reprogramming somatic cells to induced pluripotent stem (iPS) cells and directed differentiation opens up for in vitro studies of neurons from patients. The Falk group is focusing on questions in early human neurogenesis:

  • How do neural stem cells decide between self-renewal and differentiation? How are these decisions hampered in neurodevelopmental disorders? How are impaired neural stem cell proliferation, differentiation and migration resulting in less functional neurons?
  • Are in vitro human neurogenesis, migration and maturation in 2D and/or 3D systems mimicking development in health and disease?

To answer these questions we are building cellular models of the healthy and diseased human brain using reprogrammed patient cells. We derive patient specific iPS cells that are further differentiated into patient specific neuroepithelial stem (NES) cells. Both iPS and NES cell lines can be robustly expanded in culture and by applying efficient neuronal differentiation protocols we derive close to pure cultures of unlimited numbers of neurons for our studies. We use these cellular models to study proliferation, self-renewal, and differentiation potential as well as the function and subtype of derived neurons to uncover disease mechanisms.
