Innovative USask 'Mini-Brains' Could Revolutionize Alzheimer’s Treatment

In testing, Wenzel's "mini-brains" more accurately reflect a fully-fledged adult human brain, so they can be used to more closely examine neurological conditions of adult patients, such as Alzheimer disease.

And for those “mini-brains” created from the stem cells of individuals who have Alzheimer’s, Wenzel determined that the artificial organ displayed the pathology of Alzheimer’s – just on a smaller scale.

“If stem cells have the capacity to become any cell in the human body, the question then came ‘could we create something that resembles an entire organ?’” Wenzel said. “While we were developing it, I had the crazy idea that if these truly are human brains, if a patient had a disease like Alzheimer’s and we grew their ‘mini-brain,’ in theory that tiny brain would have Alzheimer’s.”

Wenzel said this technology has the potential to change the way health services are provided to those with Alzheimer’s, particularly in rural and remote communities. This groundbreaking research has already received support from the Alzheimer Society of Canada.

If Wenzel and his colleagues can create a consistent way to diagnose and treat neurological conditions like Alzheimer’s using only a small blood sample – which has a relatively long shelf life and can be couriered – instead of requiring patients to travel to hospitals or specialized clinics, it could be a tremendous resource savings for the healthcare system and a burden off of patients.

“In theory, if this tool works the way we think it does, we could just get a blood sample shipped from La Loche or La Ronge to the university and diagnose you like that,” he said.

The early proof-of-concept work on the “mini-brains” has been extremely promising – which means the next step for Wenzel is expanding the testing to a larger pool of patients.

The researchers are also interested in trying to expand the scope of the “mini-brain” research. According to Wenzel, if they can confirm the “mini-brains” accurately reflect other brain diseases or neurological conditions, they could potentially be used to speed up diagnoses or test the efficacy of drugs on patients.

As an example, Wenzel pointed to the substantial wait times to see a psychiatrist in Saskatchewan. If the “mini-brains” could be used to test which antidepressant works best on a patient suffering from depression, it could dramatically reduce the time required to see a doctor and receive a prescription.

A former high school science teacher who made the move into the world of research and academia, Wenzel said it’s the “nature of research” to come up with a hypothesis and hit close to the mark in an experiment that excites him his work.

The astounding success of the early “mini-brains,” however, has been so staggering that Wenzel admitted he still struggles to wrap his own brain around it.

“I’m still in disbelief, but it’s also extremely motivating that something like this happened,” Wenzel said. “It gives me something that I think will impact society and have actual relevance and create some change … it has a strong potential to shift the landscape of medicine.”
