Bi/ond joins forces

Bi/ond joins forces with the Eindhoven University of Technology and Luxembourg
University to develop a Midbrain-on-a-Chip model for Parkinson’s disease

Parkinson’s disease (PD) is the second most prevalent neurodegenerative disorder in the ageing
population. It is characterized by the progressive loss of dopaminergic neurons in the substantia
nigra region of the brain. Despite intensive research, the cause of the disease is still elusive, and
there is currently no disease-modifying therapy for its treatment. Therefore, it is crucial to achieving
a better understanding of the mechanisms underlying neuronal degeneration. A major shortcoming
toward this goal is the lack of human-specific predictive models for PD.
A promising approach is the development of human brain organoids, self-assembled from
induced pluripotent stem cell (iPSC), as systems to better mimic in vivo physiology. However,
maintaining these organoids alive for extended periods in standard in vitro conditions is extremely
challenging. Due to their structural complexity and large size, these three-dimensional tissue models
often suffer from suboptimal oxygen and nutrition supply, which severely limits their viability.
