Scientists find new window into the heart

Patient has scanScientists we fund in Edinburgh have developed a new tracking technique which could benefit future stem cell treatments for people suffering from heart failure.

Heart failure affects more than 750,000 people in the UK.  The condition can leave patients fighting for breath and unable to do even simple tasks like making a cup of tea.  

Scientists want to find a way to repair the heart muscle of patients with heart failure. By injecting stem cells into patients scientists hope to help their hearts beat strongly again. But they have no way of seeing where the injected cells end up in the heart.

A Sat Nav for cells  

Scientists at our Centre of Research Excellence at the University of Edinburgh may have found an answer. They discovered that by labelling immune cells with tiny iron filings they can track their movements using a powerful magnetic resonance imaging (MRI) scanner.

The MRI scanner works much like a Sat Nav by mapping the magnetic cells as they move through the body

If stem cells behave like immune cells when carrying the tiny magnetic particles, researchers think they could also follow their journey to damaged areas of the heart.

Our Research Advisor Dr Hélène Wilson, said:

“The MRI scanner works much like a Sat Nav by mapping the magnetic cells as they move through the body.”

“Scientists have shown the MRI scanner can track labelled immune cells as they move in the bloodstream, but it is important to find out whether it can do the same with injected stem cells. If successful, this opens exciting new avenues to stem cell treatments for patients with heart disease” 

Mending Broken Hearts

Our Mending Broken Hearts Appeal funds pioneering research like this into stem cell therapies and other new ways to repair the heart. We aim to literally ‘mend broken hearts’ by supporting ground-breaking research to cure heart failure.

The findings were published in the journal Circulation: Cardiovascular Imaging.
