Key advance in brain research

Australian neurobiologists and material scientists have teamed up to innovate the petri-dish to be able to grow and age live brain cells from patients with neurological disorders.

The key advance by experts at Flinders University and South Australian Health and Medical Research Institute (SAHMRI) is a critical element in achieving targeted drug treatments for individuals with neurological disorders and could enhance future studies on conditions ranging from dementia, Parkinson’s, epilepsy, autism and mental health.

Assisted by a recent $1 million injection of funding led by the Michael J Fox Foundation, Shake it up Foundation and The Hospital Research Foundation, the Bardy Lab has published the latest developments in Stem Cell Reports and will scale up the approach to test new potential treatments for Parkinson’s disease, brain cancer and a form a childhood dementia.

Flinders University PhD Bridget Milky and Associate Professor Cedric Bardy have been ‘reinventing’ the lab technique for growing brain tissue in the lab.

“Along with our patented BrainPhys medium, this new substrate will significantly improve laboratory testing on human brain cells. Advancing patient-specific pre-clinical research is so important for so many people both young and older who currently suffer from brain disorders and may not have time to wait for expensive and lengthy clinical trials with very slim chance of success,” says Associate Professor Cedric Bardy.

“I believe testing drugs on patient cells before enrolling clinical trials will be a game-changer for medical discoveries, but we need to get the model right. This study takes us closer to this goal,” he says.

“The new substrate applied to petri-dishes maintains complex electrical connections between neurons, allowing us to model the patient’s brain more accurately and determine the best treatment with more certainty,” says first author PhD candidate Bridget Milky.

An Adelaide biotech TekCyte Limited team led by company CEO Tony Simula was involved in developing the new substrate which will be manufactured at the TekCyte’s Mawson Lakes facility in South Australia.

“We look forward to improving the tools used for research and new drug discovery which could potentially shave precious years off finding the best treatment for people living with diseases such as Parkinson’s,” Dr Simula says.

The latest development is another building block on research focusing on turning patients’ skin cells into induced pluripotent stem cells and brain cells. Ongoing research is making this lab model as realistic and effective as possible.
