HUMAN HEALTH

Partner with U of T Engineering

Advances in engineering and technology — from public sanitation to antibiotics — have enabled humans to live longer, healthier lives than ever before, yet many challenges remain.

Heart disease, neurodegenerative conditions and many types of cancer have few reliable treatments. The diseases that we can control still take far too many lives because of uneven distribution of technology around the world.

U of T Engineering researchers have a track record of success in working at the intersection of medicine, life sciences and engineering to prevent illness, treat disease and improve quality of life. We are creating tissue patches that can repair damaged hearts and other organs. We are optimizing surgical schedules and finding the best places to install artificial external defibrillators (AEDs). And we are developing low-cost, point-of-care diagnostics that enable developing countries to provide better care for everyone.

U of T has established strong partnerships with 10 world-class research and teaching hospitals in Toronto, including many within walking distance of our downtown campus. Together with doctors, medical researchers, policymakers and industry, we are helping people around the world live longer, healthier lives.

RESEARCH IMPACT

Mending broken hearts

 

After a heart attack (myocardial infarction) entire sections of heart tissue die. Currently, there is no way to replace this lost tissue, but that may be about to change.

Biomedical engineering professor MILICA RADISIC (left), Canada Research Chair in Functional Cardiovascular Tissue Engineering, and her team specialize in growing human tissues outside the body. They use a polymer that is both biocompatible and biodegradeable to create mesh-like scaffolds that can be seeded with human cells. In a few days, the cells then begin to grow just as they would in a human: the team has produced pieces of heart tissue that beat with a regular rhythm and liver tissue that can metabolize certain biomolecules. Eventually, these tissue patches can be re-implanted into the body to repair damage.

Even in their current state, these lab-grown constructs are tremendously useful for screening potential drug molecules and eliminating those that may have negative effects on heart or liver tissues. Radisic has created a startup, TARA Biosystems Inc., which has licensed the technology and is working with pharmaceutical manufacturers on this application.

Coffee shops and ATMs could be life savers

 

When a patient suffers cardiac arrest, every second counts — the chances of survival decrease by 10 per cent each minute. Automated external defibrillators (AEDs) can help by shocking a heart back to life, but they are only effective if they are located somewhere accessible.

Industrial engineering professor TIMOTHY CHAN (right), Canada Research Chair in Novel Optimization and Analytics in Health and director of the Centre for Healthcare Engineering, and PhD candidate CHRISTOPHER SUN (left) studied data on cardiac arrests and availability of AEDs across Toronto, accounting not only for location, but also time of day. Their research indicates that 21.5 per cent of cardiac arrests took place near inaccessible AEDs (e.g., locked inside a closed building).

The team then created a “Top 10” list of prime spots to place AEDs. Coffee shops and ATMs topped the list due to their even spatial distribution and the fact that many are open 24 hours a day. By optimizing the locations where AEDs are deployed, the team’s research could lead to more lives being saved.

Living heart valves from stem cells

 

Today, a baby born with a faulty heart valve can receive a synthetic replacement. But as the child grows, so does the size of the valve required. This means more surgical operations, increasing the risk of complication.

Professor CRAIG SIMMONS (middle), U of T Distinguished Professor of Mechanobiology and director of U of T’s Translational Biology and Engineering Program (TBEP), is working on a solution. Using stem cells from a child’s own umbilical cord, he and his team aim to grow replacement heart valves made of living tissue. These valves would grow as the patient grows, and the use of stem cells reduces the risk that the body will reject the implant. A similar approach could be taken with blood vessels and other tissues that need to grow over time.

Simmons’ work could also accelerate the arrival of personalized medicine by helping doctors choose which treatments will be most likely to benefit a particular patient. They are growing models of heart tissue and other organs from stem cells in the lab, which can be used to screen a library of drugs and select the most effective one for a given patient’s genetic makeup.

Point-of-care testing for remote communities

 

In many parts of the world, diagnosing, monitoring and screening for infectious diseases is a complicated task. Fully equipped medical laboratories are few and far between, and patients could take weeks to get a diagnosis, during which time their symptoms often worsen.

ChipCare is a company based on research from Professor STEWART AITCHISON and his graduate student JAMES DOU (above) in Electrical and Computer Engineering. The company has created the Polyvalent Analyzer (PAx) platform, which consists of a portable, easy-to-use analyzer and low-cost, disposable microfluidic cartridges. Based on a patented optical detection method, the system provides lab-quality results in as little as 15 minutes. The rugged design does not require refrigeration, enabling it to be deployed in remote locations without access to electricity.

While the initial design was created with HIV in mind, the platform can perform tests for a range of diseases. The company has raised more than $8 million in venture capital and is now scaling operations to bring its first-generation product to market.

“The discovery of pluripotent stem cells by UofT scientists James Till and Ernest McCulloch in the early 1960s opened up the possibility of using the body’s natural mechanisms to repair damage. Today, our tissue engineers are building on that legacy, developing new therapies for conditions from heart failure to neurodegenerative disease.”

THE FUTURE OF HUMAN HEALTH RESEARCH

Commercializing stem cell technology

 

In January 2016, Prime Minister Justin Trudeau visited U of T to announce the federal government’s $20-million grant to the Centre for Commercialization of Regenerative Medicine (CCRM) to establish and operate a new Centre for Advanced Therapeutic Cell Technologies. GE Healthcare also committed $20 million to the new centre.

CCRM is the commercialization partner of Medicine by Design. The new Centre will be the first such facility in the world to use a collaborative approach between research institutions and industry to solve cell therapy manufacturing challenges. By scaling up the manufacture of stem cells and derived products, the new partnerships will accelerate potential new therapies for a wide variety of conditions, including cancer, heart disease, and autoimmune diseases.

Building the bioproducts industry

 

In the future, biotechnology companies will produce designer cells, tissue and organs for a variety of purposes, from drug testing to treatment of degenerative disease.

How do you train highly qualified personnel to work in an industry that is still developing? One strategy is to teach them how to translate their own research into successful startups. That is the goal of the Training Program in Organ-on-a-chip Engineering and Entrepreneurship, headed by Professor Milica Radisic. Funded by an NSERC Collaborative Research and Training Experience (CREATE) grant, the program includes 11 primary investigators from U of T.

Another CREATE grant in the bioproducts space is Manufacturing, Materials and Mimetics (M3), headed by University Professor MOLLY SHOICHET, Canada Research Chair in Tissue Engineering. M3 focuses on cell manufacturing, biomaterials and tissue mimetics. In partnership with the CCRM, the program will produce graduates with the scientific and business acumen to advance this knowledge to industrial application.

SPECIALIZED EDUCATIONAL OFFERINGS IN HUMAN HEALTH

The Institute of Biomaterials & Biomedical Engineering (IBBME) — a multidisciplinary research community of engineering, medicine and dentistry investigators — offers research-based graduate programs at both the Master’s and Doctoral levels, as well as a Master of Health Science (MHSc) in Clinical Engineering and a one-year Master of Engineering (MEng) that focuses on the design of biomedical devices.

At the undergraduate level, engineering students can minor in Biomedical Engineering, and Engineering Science students can major in Biomedical Systems.
