Bioprinting can produce living human tissues on demand, opening up huge possibilities for medical breakthroughs in both drug screening and developing replacement tissues. The Willerth lab was the first group in the world to use the cutting edge RX1 bioprinter from Aspect Biosystems to bioprint neural tissues similar to those found in the brain using stem cells derived from healthy patients. Similar tissues can be printed using stem cells derived from patients suffering from Parkinson's disease, recapitulating the disease phenotype in a dish. These highly customized, physiologically-relevant 3D human tissue models can screen potential drug candidates as an alternative to expensive pre-clinical animal models.

This project will bioprint both healthy and diseased neural tissues using our novel bioink in combination with Aspect Biosystems' novel trademarked Lab-on-a-Printer system and evaluate their function. We will then validate these tissue models as tools for drug screening by exposing them to compounds with known toxicity to brain tissues.

Dr. Willerth has over 16 years of experience in the area of biomaterials and tissue engineering, making her the ideal choice to lead this project. This project will lead to better health outcomes for patients suffering from neurological diseases and disorders, which account for 6.7% of the healthcare burden in Canada and improve the quality of life for B.C. residents suffering from such diseases.
